Introduction This chapter describes the integrated HP NetRAID controller and its SCSI channels, hardware, firmware, and features. This chapter also tells you about this guide and other information sources. Integrated HP NetRAID Controller The integrated HP NetRAID controller in the HP NetServer provides an integral disk array storage system. The controller uses the PCI (Peripheral Component Interconnect) standard to control data transfers on SCSI channels.
Chapter Introduction Table 1-1.
Chapter Introduction Mass storage channels SCSI A and SCSI B support the internal and external storage devices as listed in Table 1-2. Table 1-2.
Chapter Introduction Integrated HP NetRAID Controller Hardware The integrated HP NetRAID controller includes the following hardware, which is described in Table 1-3: • IOP: The IOP (I/O Processor) for the integrated HP NetRAID controller directs all functions of the controller, including command processing, PCI and SCSI bus transfers, RAID processing, drive rebuilding, cache management, and error recovery.
Chapter Introduction Integrated HP NetRAID Firmware The integrated HP NetRAID controller firmware handles all RAID and SCSI command processing and also supports the following functions: • Disconnect/Reconnect feature optimizes SCSI Bus seek. • Tagged Command Queuing allows multiple commands to be sent to the controller, thus improving random access. • Scatter/Gather supports multiple address/count pairs.
Chapter Introduction The integrated HP NetRAID controller allows disk modules to be moved to an HP NetRAID Series adapter listed above without losing data readability. They can also be moved to integrated HP NetRAID channels in the following HP NetServers without losing data readability: • HP NetServer LH 3/3r • HP NetServer LH 4/4r • HP NetServer LH 3000/3000r • HP NetServer LH 6000/6000r • HP NetServer LT 6000r NOTE HP recommends backing up data before moving disk drive modules.
Chapter Introduction Changing Capacity and RAID Levels The integrated HP NetRAID controller can expand capacity and change RAID levels of logical drives without powering down the server. • Online Capacity Expansion: You can add a physical drive to a RAID 0, 3, or 5 logical drive. This can be an online operation if you are running Novell NetWare 4.2 or 5 or Microsoft Windows NT or Windows 2000.
Chapter Introduction About This Guide This Integrated HP NetRAID Controller Configuration Guide helps you plan and configure your HP NetRAID system. It guides you through power-up, launching the HP NetServer Navigator software, configuring the HP NetRAID system, and installing a NOS-specific configuration utility. It contains a glossary, and an appendix contains worksheets to use in planning the configuration of physical and logical drives.
Chapter Introduction You should also consult the following HP NetServer documentation: • Readme file for your HP NetServer on the HP NetServer Navigator CD-ROM • Your HP NetServer installation road map (if one was supplied with your system) • Your HP NetServer user guide or HP NetServer installation guide • Technical Reference Cards or labels on the HP NetServer system chassis (for cables and SCSI ID switch settings) • Internet site: http://www.hp.
2 RAID Overview This chapter summarizes concepts and terminology used to describe RAID systems. It describes the different RAID levels available with the integrated HP NetRAID controller. For definitions of terms not introduced here, see the Glossary. RAID Overview The integrated HP NetRAID controller lets you link multiple hard disk drives together and write data across them as if they were one large drive.
Chapter 2 RAID Overview Arrays can combine disk drives that are all on one channel, or they can combine disk drives from one or two different channels. Hot Spares A hot spare is a powered-on, stand-by disk drive that is ready for use should another disk drive fail. When a disk fails, the HP NetRAID firmware can automatically rebuild the data from the failed disk onto the hot spare. The system administrator can then replace the failed disk and designate the replacement as the new hot spare disk.
Chapter 2 RAID Overview The nine physical drives are in three arrays (A0, A1, and A2) with one global hot spare. Figure 2-3. Sample Configuration with Three Arrays and Three Logical Drives Understanding RAID Levels During installation, you configure your logical drives by running a disk array configuration utility. Each of the logical drives you define must have an assigned RAID level. Each RAID level has different advantages in terms of performance, redundancy, and capacity.
Chapter 2 RAID Overview Arrays with No Redundancy: RAID Level 0 RAID 0: Striping In RAID 0 configurations, data is distributed among hard disks in the array via an algorithm called striping. Data written to a logical drive is divided into pieces called blocks. RAID 0 provides no data redundancy. If one hard disk fails, the data is lost from the entire logical drive and must be retrieved from a backup copy.
Chapter 2 RAID Overview Non-spanned Arrays with Redundancy: RAID Levels 1, 3, and 5 RAID 1: Mirroring In RAID 1 configurations, data on one disk is completely duplicated on another disk. This is called mirroring. RAID 1 must be configured on a two-disk array. (The array cannot contain more than two disk drives.) With this algorithm, if either of the two disks fail, data is available from the duplicate disk.
Chapter 2 RAID Overview RAID 3: Striping with Dedicated Parity In RAID 3 configurations, each data stripe generates one parity block to provide redundancy and data protection. The parity block is encoded information that can be used to reconstruct the data on that stripe if one of the disks fails. RAID 3 configurations dedicate one disk in the array to store all parity blocks.
Chapter 2 RAID Overview RAID 5: Striping with Distributed Parity RAID 5 is the most common configuration because it provides good overall performance and data protection with a minimum loss of storage capacity. RAID 5 distributes the parity blocks equally among all disk drives to achieve better overall performance than if a dedicated parity disk is used (RAID 3).
Chapter 2 RAID Overview Spanned Arrays: RAID Levels 10, 30, and 50 Array spanning allows the capacity of two, three, or four arrays to be combined into a single storage space. A spanned array configuration must have the same number of disk drives in each array: each array can have two disks, three disks, four disks, and so on. RAID 10: Spanning with Mirrored Arrays A RAID 10 configuration uses two, three, or four pairs of mirrored disks, spanning two, three, or four arrays, respectively.
Chapter 2 RAID Overview RAID 30: Spanning with Dedicated Parity Drives In RAID 30 configurations, parity blocks provide redundancy to a logical drive that spans two, three, or four arrays. (RAID 30 is a RAID 3 configuration with array spanning.
Chapter 2 RAID Overview RAID 50: Spanning with Distributed Parity In RAID 50 configurations, parity blocks are distributed throughout the logical drive that spans two, three, or four arrays. (RAID 50 is a RAID 5 configuration with array spanning.

3 Configuration Overview To configure your integrated HP NetRAID controller, you need to perform the following steps. Steps A through M are described in Chapters 4 through 7 of this guide. Step A. Plan Your Hardware (Chapter 4 and Worksheet A) Step H. Decide I2O Operation or NonI2O Operation (Chapter 6) Step B. Plan Arrays and Logical Drives (Chapter 4 and Worksheets A and B) Step I. Use HP NetServer Navigator CD-ROM to Prepare Diskettes (Chapter 6) Step C. Verify Hardware Setup (Chapter 5) Step J.
4 Planning Overview Before configuring your disk array subsystem, you should invest some time in planning the configuration that best suits your computing environment. The options you choose depend on factors such as the host operating system used and your requirements for data protection, performance, and capacity. This chapter guides you through the planning process. • Step A, Plan Your Hardware, is the first step. • Step B, Plan Arrays and Logical Drives, is the second step.
Chapter 4 Planning Sample Worksheet A Figure 4-1 shows a sample Configuration Worksheet A. (See Appendix B for a complete explanation of this example.
Chapter 4 NOTE Planning SCSI ID 7 is reserved for the integrated HP NetRAID controller. For internal mass storage in HP NetServer LH 3000/3000r, LH 6000/6000r, and LT 6000r, SCSI ID 5 is reserved for the SAF-TE (SCSI Access Fault-Tolerant Enclosure) processor that manages the hot-swap mass storage cage. For an external mass storage enclosure with a SAF-TE processor, a SCSI ID is reserved for that processor. The number of the reserved SCSI ID varies with the type of external enclosure.
Chapter 4 Planning Table 4-1.
Chapter 4 Planning Detailed descriptions of the SCSI channels are as follows: • HP NetServer LH 3/3r and LH 4/4r: ◊ SCSI A has these characteristics: ∗ By default, SCSI channel A is connected to the hot-swap mass storage cage that was shipped with your HP NetServer. ∗ By default, the integrated HP NetRAID subsystem is enabled for SCSI A. ◊ SCSI B has these characteristics: ∗ By default, SCSI channel B is connected to the non-hot-swap devices.
Chapter 4 Planning • HP NetServer LH 3000/3000r and LH 6000/6000r: ◊ SCSI A has these characteristics: ∗ By default, SCSI channel A is connected to the internal hot-swap mass storage cage that was shipped with your HP NetServer. ∗ By default, the integrated HP NetRAID subsystem is enabled for SCSI A. ◊ SCSI B has these characteristics: ∗ By default, SCSI channel B is not connected. An optional internal hot-swap mass storage cage or external enclosure could be connected to it.
Chapter 4 Planning LUNs, and you want to operate in HP NetRAID mode, you must connect the device to a SCSI controller accessory board. ∗ If integrated HP NetRAID is enabled and you plan to use a tape backup device, you must connect the device to a SCSI controller accessory board. HP NetRAID Channels The integrated HP NetRAID controller refers to channels as 0 and 1. l For HP NetServer LH 3/3r and LH 4/4r, if only one HP NetRAID channel is enabled, it becomes Channel 0.
Chapter 4 Planning How to Handle Non-Hot-Swap Devices Non-hot swap devices in HP NetServer LH 3/3r and LH 4/4r are on SCSI channel B (unless they have been connected to a separate SCSI controller accessory board). Non hot-swap devices in HP NetServer LH 3000/3000r and LH 6000/6000r are independent of integrated HP NetRAID channels.
Chapter 4 Planning SCSI Transfer Rate ! On Worksheet A, record the SCSI transfer rate for each channel. The default SCSI transfer rate is Ultra2 because the internal hot-swap mass storage cage supports Ultra2 disk drive modules. However, you can change the SCSI transfer rate to Fast or Ultra if the channel is connected to an external mass storage enclosure.
Chapter 4 Planning • For each array, automatic configuration looks to see if you have asked to implement redundancy (checked the Redundancy box). If you are not using redundancy, all logical drives are assigned RAID level 0. • If an array contains two drives and you checked Redundancy, the logical drive is assigned RAID level 1. • If a group contains three to five drives and you checked Redundancy, the logical drive is assigned RAID level 5.
Chapter 4 Planning • Decide the rebuild rate • Plan logical drives Plan Your Non-Hot-Swap Devices ! For HP NetServer LH 3/3r and LH 4/4r, if you plan to enable integrated HP NetRAID on SCSI B, you need to decide how to use any non-hot-swap SCSI devices on the SE connector. For HP NetServer LT 6000r, you need to decide how to use any non-hot-swap SCSI devices on the external SCSI B channel. For each of these non-hot-swap devices, log its array number in Worksheet A.
Chapter 4 Planning When you create your arrays, you should look ahead toward the logical drives that you will configure later. (Logical drives are discussed in "Plan Logical Drives" later in this chapter.) Here are some considerations about logical drives that might impact how you set up your arrays: • Consider what RAID levels you will need. ◊ Different RAID levels require different minimum numbers of physical drives.
Chapter 4 Planning Figure 4-2. Two Logical Drives Where Whole Arrays Appear on Different Channels Figure 4-3 shows the same configuration, except Array A0 contains physical drives from both Channel 0 and Channel 1. Figure 4-3.
Chapter 4 Planning Plan Hot Spares (Optional) ! On Worksheet A, log any hot spare disk modules and indicate whether each is global or dedicated to a particular array. A hot spare is a powered-on, stand-by disk that is ready for use should another disk fail. When a disk fails, the HP NetRAID firmware can automatically rebuild the data from the failed disk onto the hot spare. Unless a rebuild occurs, a hot spare does not contain user data.
Chapter 4 Planning Plan Logical Drives Logical drives are virtual drives configured within an array or across arrays. Logical drives can take three forms: • A logical drive can use all of the storage capacity of one array. • A logical drive can use less than the available storage capacity of one array. The remaining capacity can be used by one or more logical drives. • A logical drive can span arrays by using capacity in two, three, or four different arrays.
Chapter 4 Planning ◊ Although each drive in an array must have the same capacity, one logical drive can span two or more arrays with different capacities. For example, one array might contain three drives of 2 GB each, and the second array might contain three drives of 4 GB each. One logical drive can span both of these arrays. ◊ Spanned arrays must be numbered consecutively.
Chapter 4 Planning Logical Drives, RAID Levels, and Array Spanning ! On Worksheet B, logical drives are numbered LD0 through LD7.
Chapter 4 Planning Write Policy ! When the IOP writes to disk, the data is first written to the cache on the assumption that the IOP will read it again soon. The two Write policies are: • Write-Through: In a write-through cache, data is written to disk at the same time it is cached. This setting provides better security because entries are always copied to disk. This is the default setting. • Write Back: In a write-back cache, data is written to disk only when it is forced out of the cache.
Chapter 4 Planning Cache Policy ! HP NetRAID lets you choose one of two cache policies: • Cached I/O: Reads are always cached regardless of randomness. The selected Read policy (Read-Ahead, Normal, or Adaptive) and Write policy (Write-Through and Write-Back) always apply. This is the default setting. • Direct I/O: First reads to a new location always come directly from the disk. If a location is read repeatedly, then the Read policy as selected will apply and the read data will be cached.
5 Configuration Overview This chapter covers Steps C, D, E, F, and G of the installation procedure. You should already have completed Step A, "Plan Your Hardware," and Step B, "Plan Arrays and Logical Drives," in Chapter 4. Step C. Verify Hardware Setup Verify that your hardware setup matches the plans you sketched in Worksheet A.

Go to Step 7. • If the drives configuration is not correct, answer No. • If neither configuration is correct (or if you tried the steps above and the configuration mismatch persists), follow Steps 6, 7, and 8 to clear configuration information from integrated HP NetRAID NVRAM and exit. Then restore from a backup. 6.
Chapter 5 Configuration 3. If a power-on password has been set, provide it when prompted. 4. When the Setup Utility menu is first displayed, the Configuration menu is also displayed. (If the Configuration menu is not displayed, use the left arrow key to highlight Configuration on the Main menu.) The system time and system date are displayed. If either needs to be changed, use the down arrow on the keyboard to highlight the item. Then follow the instructions on the screen. Verify Boot Order 5.
Chapter 5 Configuration 11. The Embedded LAN and SCSI Settings submenu is displayed. If HP NetRAID/LVD SCSI is not already highlighted, use the up and down arrows to highlight it. Read the values in the brackets to determine whether HP NetRAID is enabled. ◊ Enable LVD SCSI indicates that LVD SCSI is enabled and HP NetRAID is disabled. This is the setting for non-RAID operation of the mass storage connected to SCSI A and B on the I/O board.
Chapter 5 Configuration Step E. Launch HP NetRAID Assistant Start HP NetServer Navigator CD-ROM To launch HP NetRAID Assistant, start the HP NetServer that you are configuring from the HP NetServer Navigator CD-ROM. Ensure that all the external SCSI devices power up before or at the same time as the host computer.
Chapter 5 Configuration HP NetRAID Assistant Figure 5-1. HP NetRAID Assistant Figure 5-1 shows a typical configuration of HP NetServer LH 3/3r or LH 4/4r where SCSI A is included in the HP NetRAID subsystem and SCSI B is excluded. If you include both SCSI A and SCSI B, you see two channel columns of physical devices. NOTE For HP NetServer LH 3000/3000r, LH 6000/6000r, and LT 6000r, HP NetRAID Assistant always displays two channel columns.
Chapter 5 Configuration The HP NetRAID Assistant window contains the following features from top to bottom: • Menu bar: The menu bar activates pull-down menus for Configuration, Adapter, Physical Drives, Logical Drives, Progress, and Help. • Toolbar: The toolbar icons are separated into four categories of functions: Configuration, Properties, Miscellaneous, and Other. They provide shortcuts to access the menu options. Figure 5-2.
Chapter 5 Configuration NOTE For internal mass storage in HP NetServer LH 3000/3000r and LH 6000/6000r, and LT 6000r, SCSI ID 5 is reserved for the SAF-TE processor that manages the hot-swap mass storage cage. For an external mass storage enclosure with a SAF-TE processor, a SCSI ID is reserved for that processor. The number of the reserved SCSI ID varies with the type of external enclosure.
Chapter 5 Configuration Select Adapter to Configure If you installed one or more HP NetRAID Series adapters, look in the Adapter box to see if the integrated HP NetRAID controller is displayed. The integrated HP NetRAID controller is always defined as Adapter 0. If not, select it from the pull-down list. Clear Configuration You should clear the configuration to prepare it for the new configuration. To clear the existing configuration: 1. Select the Configuration menu. 2. Choose Clear Configuration. 3.
Chapter 5 Configuration Assign Global Hot Spares NOTE Refer to Worksheet A when assigning hot spares. To assign any physical drives to the global hot spare pool: 1. Click on a Ready physical drive in the Physical Devices box. This drive must have capacity that is at least as great as any drive it will replace. You can select more than one Ready drive if you want to create more than one global hot spare. Clicking on a Ready drive either selects it or deselects it. 2.
Chapter 5 Configuration Figure 5-3. HP NetRAID Assistant Wizard Starting Window 3. Click one of the following configuration modes: ◊ Select Custom if you want to define the arrays and logical drives and set their parameters. ◊ Select Automatic if you want the HP NetRAID Assistant Wizard to define the arrays and logical drives (and set their parameters) for you automatically.

The HP NetRAID Assistant Wizard Array Definition window appears, displaying the Physical Devices and Logical Devices configured on your system. It will be similar to the display shown in Figure 5-4 depending on your configuration. The "new array" in the Logical Devices box shows where a new array can be defined. Figure 5-4.
Chapter 5 Configuration 4. When the array is complete, click the Accept Array button. All physical drives assigned to arrays display their array numbers to the right of the SCSI ID. The numbering is zero-based. For example, A0 designates a physical drive assigned to Array 0. 5. The next new array appears. Assign physical drives to it as described above. Be sure to click the Accept Array button to close the array. To assign physical drives to an existing (not new) array: 1.
Chapter 5 Configuration 2. Click the Reclaim button to convert the hot spares to Ready physical drives. When you are finished defining arrays and dedicating hot spares: Click the Next button. Define Logical Drives NOTE Refer to Worksheet B when defining logical drives. After you finish defining arrays and dedicating hot spares, and click Next, the HP NetRAID Assistant Wizard Logical Drive Definition window appears. A sample window is shown in Figure 5-5. Figure 5-5.
Chapter 5 Configuration The window is ready for you to define Logical Drive 0. • The Logical Drive Parameters box shows the number of the logical drive being defined and has boxes to set its RAID level and size. • The Span Arrays check box turns array spanning on or off. • The Advanced button leads to more parameters, which are preset but can be changed. • The Logical Devices box depicts the arrays, the logical drives on each array, and the global hot spare pool.
Chapter 5 Configuration NOTE The arrays to be spanned must have sequential array numbers and each array must contain the same number of physical drives. HP NetRAID Assistant will attempt to span up to four arrays. Array spanning will stop when: • It has created a logical drive of the size you specify in Step 2 below. • The next sequentially numbered array has a different number of drives. (Spanned arrays must contain the same number of drives in each array.
Chapter 5 Configuration Preview Configuration NOTE Refer to Worksheets A and B when checking the configuration. The HP NetRAID Assistant Wizard Configuration Preview window, shown in Figure 5-6, displays the configuration proposed for the physical and logical drives. Figure 5-6.

Chapter 6 HP NetRAID Software Step I. Use HP NetServer Navigator CD-ROM to Prepare Diskettes In this step, you will use the HP NetServer Navigator CD-ROM to create the diskettes you need to install the HP NetRAID drivers and the HP NetRAID configuration utility specific to your NOS. The diskettes that you need to create may depend upon whether you plan to use Installation Assistant's automatic mode of NOS installation, or whether you plan to install the NOS manually.
Chapter 6 HP NetRAID Software • For IBM OS/2, SCO UnixWare, or SCO OpenServer, create the diskette(s) containing the HP NetRAID drivers and instructions for installing the NOS. The NOS-specific configuration utility will also be copied to the drivers diskette(s). Check Latest Versions To ensure that you have the latest versions of the software, obtain the current Status Report for your HP NetServer Navigator CD-ROM.
Chapter 6 HP NetRAID Software Using a Separate Workstation to Create Drivers Diskette and Instructions To use a separate PC workstation to create the diskette(s) containing the drivers for your NOS and the instructions for installing the NOS, do the following: 1. Turn on the workstation and monitor, if they are not already on, and log on if necessary. 2. Insert the HP NetServer Navigator CD-ROM into the drive.
Chapter 6 HP NetRAID Software Using the HP NetServer to Create Drivers Diskette and Instructions To use the HP NetServer you are configuring to create the diskette(s) containing the drivers for your NOS and the instructions for installing the NOS, do the following: 1. Turn on the HP NetServer and monitor, if they are not already on, and insert the HP NetServer Navigator CD-ROM into the drive. Turn off the HP NetServer power, wait 10 seconds, and turn it back on again. 2.
Chapter 6 HP NetRAID Software Make NOS-specific Configuration Utility Diskette If you plan to install Windows NT, Windows 2000, or Novell NetWare, you must make another diskette containing the NOS-specific configuration utility. NOTE You can skip this step if you plan to install IBM OS/2, SCO UnixWare, or SCO OpenServer. The NOS-specific configuration utility was already copied to the drivers diskette(s). Go to "Print NOS Installation Instructions" later in this chapter.
Chapter 6 HP NetRAID Software Using the HP NetServer to Create NOS-specific Configuration Utility Diskette To use the HP NetServer to create the diskette(s) needed to install the NOSspecific utility for Windows NT, Windows 2000, or NetWare: 1. From the HP Navigator Main Menu, choose NetServer Utilities. 2. Choose Diskette Library. 3. From the Diskette Library, do the following: ◊ For Windows NT or Windows 2000, create the utility diskette by selecting NetRAID Software for Windows in the diskette library.
Chapter 6 HP NetRAID Software NOTE For I2O operation under NetWare 4.2 or 5, load the NOS manually, rather than using HP's automatic mode of NOS installation. Install HP NetRAID Series Driver Load the appropriate driver(s) as instructed in the NOS Installation Instructions that you printed in Step I earlier in this chapter. The driver names are listed in Table 6-2. NOTE For I2O operation under NetWare 4.
Chapter 6 HP NetRAID Software Step K. Install NOS-specific Configuration Utility In this step, you install the configuration utility specific to your NOS. • If you are using any version of Microsoft Windows NT or Windows 2000, you install the HP NetRAID Assistant utility. This is the Windows NT and Windows 2000 version of the utility you used to configure your system in Chapter 5. • If you are using Novell NetWare, IBM OS/2, SCO UnixWare, or SCO OpenServer, you install the HP NetRAID Config utility.
Chapter 6 HP NetRAID Software Microsoft Windows NT Terminal Server Edition NOTE Windows NT Terminal Server Edition must be operating in INSTALL mode when you install the HP NetRAID software for Windows NT. Otherwise, the administrator may see it as properly installed, but it may fail for other users. There are three relevant commands for the DOS prompt: • CHANGE USER /INSTALL = sets it to install mode. • CHANGE USER /EXECUTE = sets it to execute mode.

Chapter 6 HP NetRAID Software ◊ You do not need to set the SCSI transfer rate if you are using internal hot-swap mass storage only, since it is Ultra2. • To operate in I2O mode, set the PCI class code to I2O mode. NOTE Instead of using HP NetRAID Express Tools to change the PCI class code, you can use the Set Class utility in the "NetRAID Software for DOS" utility in the diskette library on the HP NetServer Navigator CD-ROM.
Chapter 6 HP NetRAID Software To Disable the HP NetRAID BIOS If you want to prevent the system from booting from the integrated HP NetRAID controller or from any of the following HP NetRAID Series adapters, you can disable the HP NetRAID BIOS: • HP NetRAID (D4943A) • HP NetRAID-1 (D4992A) • HP NetRAID-3Si (D5955A) • HP NetRAID-1Si (D2140A) To disable the HP NetRAID BIOS for all adapters in the system, choose Disable BIOS from the Tools Management menu. To Change the SCSI Transfer Rate 1.
Chapter 6 HP NetRAID Software To Change the PCI Class Code to I2O To support I2O operation, set the PCI class code to I2O on the integrated HP NetRAID controller and on all HP NetRAID Series adapters in the system, other than HP NetRAID and HP NetRAID-1 adapters, which do not support I2O. NOTE Instead of using HP NetRAID Express Tools to change the PCI class code, you can use the Set Class utility in the "NetRAID Software for DOS" utility in the diskette library on the HP NetServer Navigator CD-ROM.
7 Preparing for Online Capacity Expansion Step M. Prepare for Online Capacity Expansion The HP NetRAID Online Capacity Expansion feature allows you to add new storage capacity to drives controlled by an integrated HP NetRAID controller without rebooting the server. Online Capacity Expansion has these restrictions: • You can use Online Capacity Expansion with any logical drive of RAID level 0, 3, or 5.
Chapter 7 Preparing for Online Capacity Expansion Refer to one of the following sections in this chapter: • See "Preparing for Online Capacity Expansion Under NetWare 4.2" if you are using Novell NetWare 4.2. • See "Preparing for Online Capacity Expansion Under NetWare 5" if you are using Novell NetWare 5. • See "Preparing for Online Capacity Expansion under Windows NT" if you are using Microsoft Windows NT.
Chapter 7 Preparing for Online Capacity Expansion Under NetWare 4.2, you create a 144-GB partition, but within that partition you only create a logical drive totaling 12 GB or less. Since there is unused partition space, the physical storage of 12 GB can be expanded online by adding another hard disk drive, but the partition remains at 144 GB. Precautions When using the Online Capacity Expansion feature, it is very important that you do not create volumes that exceed the actual physical capacity.
Chapter 7 Preparing for Online Capacity Expansion NOTE SFT-3 and mirroring users: Novell's operating system, which provides system level fault tolerance by mirroring two systems, is not compatible with the Online Capacity Expansion feature. SFT-3 mirrors disk storage on a partition basis rather than a volume basis. Because of the virtual space created within the partition, SFT-3 cannot successfully mirror the partitions. This limitation also applies to regular mirroring (without SFT-3) of volumes.
Chapter 7 Preparing for Online Capacity Expansion Preparation Steps for NetWare 4.2 This section makes the following assumptions: • You have already configured your HP NetRAID system as discussed in Chapter 5. You should have created only one logical drive per array. • You have initialized your logical drives. NOTE It is important to initialize your logical drives.
Chapter 7 Preparing for Online Capacity Expansion 5. Choose Logical Drive from the Objects menu. 6. From the Logical Drives menu, choose the logical drive you want to prepare for expansion. 7. From the Logical Drive menu for the drive you want to prepare, choose Properties. 8. Choose Virtual Sizing. 9. On the Virtual Size Feature menu, choose Enable, and confirm your choice. 10. Press Esc twice to return to the Logical Drive menu.
Chapter 7 Preparing for Online Capacity Expansion III. Create the NetWare Volume How you create the NetWare volume depends on where you installed NetWare. • For drives that do not contain the NetWare 4.2 operating system, see "Create Volumes on Drives that do not Contain NetWare 4.2." • If NetWare 4.2 was installed on a disk array, see "Create Volumes on Drives That Contain NetWare 4.2." Create Volumes on Drives that do not Contain NetWare 4.
Chapter 7 Preparing for Online Capacity Expansion The new volume is now ready for use. Assume, for example, that the volume is called VOL1 and that its physical capacity is 12 GB. Its partition is 144 GB. Leave the remaining virtual storage space (144 GB minus 12 GB) as unused. You can write data up to 12 GB on the drive. Create Volumes on Drives that Contain NetWare 4.2 Sometimes it is desirable to have the network operating system reside on a disk array.
Chapter 7 Preparing for Online Capacity Expansion Preparing for Online Capacity Expansion under NetWare 5 About Capacity Expansion under NetWare 5 Normally, to add capacity you must shut down the server to reconfigure and then restore data, or you must add the new storage space as a new volume. The Online Capacity Expansion feature allows you to expand an existing logical drive without shutting down the server. The Online Capacity Expansion feature cannot be used if a logical drive spans multiple arrays.
Chapter 7 Preparing for Online Capacity Expansion In most installations, the operating system is installed on a SCSI drive connected outside of the HP NetRAID system. However, NetWare 5 can reside on a disk array in the HP NetRAID system to achieve redundancy. Preparation Steps for NetWare 5 This section makes the following assumptions: • You have already configured your HP NetRAID system as discussed in Chapter 5. You should have created only one logical drive per array.
Chapter 7 Preparing for Online Capacity Expansion 1. Restart the host HP NetServer, and watch for the message: Option: Experienced users may press for HP NetRAID Express Tools now. Firmware Initializing 2. When the message is displayed, press . When the system stops scanning, HP NetRAID Express Tools starts and displays the Tools Management menu. 3.
Chapter 7 Preparing for Online Capacity Expansion Preparing for Online Capacity Expansion under Windows NT About Capacity Expansion under Windows NT Normally, adding capacity requires shutting down the server to reconfigure or restore an existing volume or to add the new storage space as a new volume. Using the Online Capacity Expansion feature allows you to expand an existing logical drive without shutting down the server.
Chapter 7 Preparing for Online Capacity Expansion logical drive can be checked with the HP NetRAID Assistant under Windows NT. The Online Capacity Expansion feature cannot be used if a logical drive spans multiple arrays. Each array can contain only one logical drive. Reconstruction (for the purposes of adding a drive to an existing array) can only be done on an array having a single logical drive. It is also important to plan future storage expansion into your installation.
Chapter 7 Preparing for Online Capacity Expansion I. Enable Virtual Sizing NOTE Clearing a previous configuration does not reset the virtual sizing setting for a logical drive. Use the Reset to Factory Defaults option in HP NetRAID Express Tools to disable virtual sizing for all logical drives, or manually change the setting as described below. 1. Restart the host HP NetServer, and watch for the message: Option: Experienced users may press for HP NetRAID Express Tools now.
Chapter 7 Preparing for Online Capacity Expansion 12. To exit, press Esc until you see the Exit? box, and choose Yes. II. Start Windows NT and Enter the Disk Administrator Start Windows NT, and enter the Disk Administrator. Here you see the new logical drive shown as a single unpartitioned/unformatted drive of 500 GB. Although there might be only 12 GB of real storage space on the logical drive, the Online Capacity Expansion feature creates a virtual drive of 500 GB. III.
Chapter 7 Preparing for Online Capacity Expansion Partition and Format a Drive that Contains Windows NT Sometimes it is desirable to have the network operating system reside on a disk array. The advantage is that the NOS resides on a redundant drive. Virtual sizing can be used with a disk array that is used as the boot device and also contains user data. The key limitation is that Windows NT only allows a FAT boot partition size of 4 GB or less.
Chapter 7 Preparing for Online Capacity Expansion To actually expand capacity online in Basic Disk Mode, you will create a new volume with a new drive letter. Capacity can be expanded online again in the future. Refer to your Windows 2000 documentation for information about adding a new volume online to expand capacity online. Preparation Steps for Windows 2000 This section makes the following assumptions: • You have already configured your HP NetRAID system as discussed in Chapter 5.
Chapter 7 Preparing for Online Capacity Expansion To Disable Virtual Sizing NOTE Clearing a previous configuration does not reset the virtual sizing setting for a logical drive. Use the Reset to Factory Defaults option in HP NetRAID Express Tools to disable virtual sizing for all logical drives, or manually change the setting as described below. The factory default is that virtual sizing is disabled. If virtual sizing has been enabled, disable it as follows: 1.
Chapter 7 Preparing for Online Capacity Expansion 11. If you have installed one or more HP NetRAID Series adapters, press Esc to return to the Objects menu. Enable virtual sizing on the logical drives of all adapters as necessary. 12. To exit, press Esc until you see the Exit? box, and choose Yes.

Glossary Disk Array Terms and Technologies Array: An array of disk modules combines the storage space on the disk modules into a single segment of contiguous storage space. The integrated HP NetRAID controller can group disk modules on one or more of its SCSI channels into an array. A hot spare disk module does not participate in an array.
Glossary volume can then be expanded into the virtual space by adding a physical disk through reconstruction. Reconstruction is only permitted on a logical drive that occupies a single array and is the only logical drive in the array. You cannot use online capacity expansion on logical drives that span arrays (RAID levels 10, 30, or 50). Channel: An electrical path for the transfer of data and control information between a disk and a disk controller.
Glossary pass a Consistency Check. Arrays work without initializing, but they may fail a Consistency Check because parity fields may not have been generated. IOP: The IOP (I/O Processor) for the integrated HP NetRAID controller directs all functions of the controller, including command processing, PCI and SCSI bus transfers, RAID processing, drive rebuilding, cache management, and error recovery. Logical Drive: A virtual drive within an array, which may occupy more than one physical disk.
Glossary reconstruct one of the parent data sets; however, parity data do not fully duplicate the parent data sets. In RAID, this method is applied to entire drives or stripes across all disk drives in an array. Parity consists of Dedicated Parity, in which the parity of the data on two or more disks is stored on an additional disk, and Distributed Parity, in which the parity data are distributed among all the disks in the system.
Glossary • RAID 1 has mirrored redundancy. It requires two physical drives in an array. • RAID 3 has parity redundancy with a dedicated parity disk. It requires three or more physical drives in an array. • RAID 5 has parity redundancy distributed over all the disks in the array. It requires three or more physical drives in an array. RAID levels 10, 30, and 50 result when logical drives span arrays. Table 2-2 in Chapter 2 describes RAID levels for logical drives that span arrays.
Glossary SAF-TE: SCSI Access Fault-Tolerant Enclosure; a processor that manages a hotswap mass storage cage or enclosure. SCSI Channel: The integrated HP NetRAID controller controls the disk drives via SCSI-2 buses called "channels" over which the system transfers data in Fastand-Wide, Ultra SCSI, or Ultra2 SCSI mode. SCSI Disk Status: A SCSI disk module (physical drive) can be in one of five states: • Ready: a powered-on and operational disk that has not been configured.
Glossary Virtual Sizing: This setting, when enabled for a logical drive, causes the controller to report the logical drive size larger than the actual physical capacity. The "virtual" space allows for online capacity expansion. Write Policy: When the processor writes to disk, the data is first written to the cache on the assumption that the processor will probably read it again soon.
