1 Introduction HP NetRAID Series Adapters The HP NetRAID (HP D4943A), HP NetRAID-1 (HP D4992A), and HP NetRAID-3Si (D5955A) adapters provide an interface between the host system and a disk array storage system. The adapters use the PCI (Peripheral Component Interconnect) standard to control data transfers on one to three SCSI channels. The HP NetRAID Series adapters support the operating systems listed below, for which drivers are provided. Network Operating System Microsoft Windows NT 4.
Chapter 1 Introduction Features of the HP NetRAID Series Adapters The HP NetRAID, HP NetRAID-1 and HP NetRAID-3Si adapters are highperformance, intelligent PCI-to-SCSI host adapters with RAID control capabilities. The HP NetRAID Series adapters have SCSI channels with both internal and external connections. Channels and Devices HP NetRAID Series adapters support channels with both internal and external connections. For each channel, you can have either one internal, or one external connection.
Chapter 1 Introduction HP NetRAID-3Si External SCSI Cables Channel External SCSI Cable 0 D6020A(1) 1 D3637C or D6020A 2 D6020A(1) (1) External connections to both Channel 0 and Channel 2 at the same time require two D6020A SCSI Cables. The connectors for Channels 0 and 2 are very close together, and these cables have offset connectors that allow them to fit side-by-side. If the necessary cables were not supplied with your system, see HP's Order Assistant for ordering information.
Chapter 1 Introduction HP NetRAID Devices Per Channel Channel Internal Connection 0 6 External Connection* 6 or 8 1 6 6 or 8 2 6 ** * External storage with the HP Storage System/6 supports a maximum of six Fast/Wide SCSI devices, while external storage with the HP Rack Storage/8 supports a maximum of eight Fast/Wide or Ultra/Wide SCSI devices. ** The HP NetRAID adapter does not have an external connection for Channel 2.
Chapter 1 Introduction HP NetRAID-1 Devices Per Channel Channel Internal Connection 0 6 External Connection * 6 or 8 * External storage with the HP Storage System/6 supports a maximum of six Fast/Wide SCSI devices, while external storage with the HP Rack Storage/8 supports a maximum of eight Fast/Wide or Ultra/Wide SCSI devices.
Chapter 1 Introduction • For the HP NetRAID-1 adapter, cache memory resides in a 4 MB nonbattery-backed 60-ns FPM DRAM SIMM and cannot be upgraded. NOTE The HP NetRAID-1 adapter does not have a Battery Backup Unit. The HP NetRAID Series adapters support Direct and Cached I/O and Write Through or Write Back caching, which can be selected for each logical drive.
Chapter 1 Introduction New Features of HP NetRAID Series Adapters New features of HP NetRAID Series adapters include: • Enhanced Array Spanning • Enhanced Configuration Replication • Support for Clustering • I2O Support (HP NetRAID-3Si adapters only) Enhanced Array Spanning The HP NetRAID Series adapters allow up to four arrays to be spanned together as one logical drive, rather than the two-array maximum supported previously.
Chapter 1 Introduction I2O Support (HP NetRAID-3Si Adapters Only) HP NetRAID-3Si adapters support I2O (Intelligent Input/Output) with some operating systems. For a complete list of operating systems for which HP NetRAID I2O drivers are available, see the HP web site at www.hp.
Chapter 1 Introduction Changing Capacity and RAID Levels HP NetRAID Series adapters 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 Microsoft Windows NT or Novell NetWare; otherwise, capacity expansion is an offline operation only.
Chapter 1 Introduction The HP NetRAID Series Installation and Configuration Guide is intended to be used in conjunction with your HP NetServer documentation. Refer to your system documentation for details such as cable product numbers and I/O slot boot order. If you are setting up your HP NetServer for the first time, begin with the HP NetServer Installation Road Map that came with your system.
Chapter 1 CAUTION Introduction All HP NetRAID adapter cards are sensitive to static electricity and can easily be damaged by improper handling. Using a grounding strap is recommended. Read the following information carefully before you handle the accessory: • Leave the adapter card in the antistatic bag until you are ready to install it. • If possible, use an antistatic wrist strap and grounding mat.
2 RAID Overview This chapter summarizes concepts and terminology used to describe RAID systems. It describes the different RAID levels available with the HP NetRAID Series adapters. For definitions of terms not introduced here, see the Glossary. RAID Overview HP NetRAID Series adapters let 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 two or three different channels. Hot Spare 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 adapter's firmware can automatically rebuild the data from the failed disk onto the hot spare.
Chapter 2 RAID Overview 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. HP NetRAID Series adapters support both nonspanned array and spanned array configurations.
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 With HP NetRAID and NetRAID-3Si adapters, 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. NOTE With HP NetRAID-1, a single logical drive can span only two arrays and supports a maximum of six to eight physical drives.
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 Installation and Configuration Overview To install and configure your HP NetRAID Series adapter, you need to perform the following steps. Steps A through N are described in Chapters 4 through 7 of this guide. Step A. Plan Hardware (Chapter 4 and Worksheet A) Step H. Save Configuration and Initialize (Chapter 5)) Step B. Plan Arrays and Logical Drives (Chapter 4 and Worksheets A and B) Step I. Decide Which HP NetRAID Driver You Need (Chapter 6) Step C. Prepare the Adapter (Chapter 5) Step J.
4 Planning Overview Before attempting to install and configure 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 • Performance requirements • Storage capacity requirements • Whether you want hot spare capability Sample Worksheet A Figure 4-1 shows a sample Configuration Worksheet A. (See Appendix C for a complete explanation of this example.) Figure 4-1.
Chapter 4 Planning Multiple Adapters The disk array drivers and firmware will support up to six adapters, but your particular model of HP NetServer may have fewer PCI slots available. Be sure to check your system's PCI I/O slot availability and any slot restrictions before purchasing another adapter. If you will be configuring more than one adapter, make one photocopy of Worksheets A and B for each adapter.
Chapter 4 ! ! Planning Log the adapter's PCI slot on Worksheet A. Channels In this section you determine which physical devices will connect to each SCSI channel of the adapter. Record the SCSI ID number and physical capacity of each disk drive in the correct channel on Worksheet A. No two devices on a single channel can have the same SCSI ID. Physical drives on different channels can be assigned to the same array.
Chapter 4 Planning Step B. Plan Arrays and Logical Drives There are two ways to set up arrays and logical drives. • Automatic configuration is explained for those users who do not want to customize their arrays and logical drives. • Custom configurations permit you to create exactly the configuration that best suits your needs. Automatic Configuration Automatic mode defines the arrays and logical drives for you, and sets their parameters. It makes configuration easy.
Chapter 4 Planning Custom Configuration To plan a custom configuration, you will do the following: • Plan your arrays • Plan hot spares • Decide the rebuild rate • Plan logical drives ! Plan Your Arrays In this section you specify which physical drives are assigned to which arrays. For each physical disk drive that is assigned to an array, log its array number in Worksheet A. When creating your arrays, please consider the following: • Group together physical drives that have the same capacity.
Chapter 4 Planning • Consider what RAID levels you will need. ◊ Different RAID levels require different minimum numbers of physical drives. For example, RAID 1 requires exactly two physical drives, RAID levels 3 and 5 require at least three physical drives, and arrays with only one physical drive must be assigned RAID 0. ◊ Different RAID levels reserve different amounts of capacity to provide redundancy. • A single array can be divided into a maximum of eight logical drives.
Chapter 4 Planning Figure 4-2. Three Logical Drives Where Each Array Uses a Different Channel Figure 4-3 shows the same configuration, except Array A1 contains physical drives from both Channel 0 and Channel 1, and Array 2 contains physical drives on Channels 1 and 2. Figure 4-3.
Chapter 4 ! Planning Plan Hot Spares (Optional) On Worksheet A for each adapter, 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 disk array controller's 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 4 MB each, and the second array might contain three drives of 12 MB each. One logical drive can span both of these arrays. ◊ Spanned arrays must be numbered consecutively.
Chapter 4 Planning Figure 4-4. Sample Worksheet B ! Logical Drives, RAID Levels, and Array Spanning On Worksheet B, logical drives are numbered LD0 through LD7.
Chapter 4 ! Planning Logical Drive Size ! You can calculate the usable capacity to assign to each logical drive, or you can let the HP NetRAID Assistant Wizard specify it during configuration. If you calculate logical drive capacity, record it in Worksheet B. If you want a logical drive to occupy less space than is available on one array, you must enter the logical drive size. Stripe Size (Stripe Depth) Stripe size is the amount of data contiguously written to each disk in an array.
Chapter 4 Planning • Write Back: In a write-back cache, data is written to disk only when it is forced out of the cache. Write-back is efficient, because an entry may be written many times in the cache without a disk access. Write Back can be used if an Uninterruptible Power Supply maintains the data in cache memory in the event of a power failure. NOTE ! Write Back is not certified for any logical drive used as a Novell NetWare volume. For each logical drive, record the write policy in Worksheet B.
5 Installation and Configuration Overview This chapter covers Steps C, D, E, F, G, and H 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. Prepare the Adapter In this step you install the adapter into the HP NetServer.
Chapter 5 Installation and Configuration Remove the board extender now, before you connect the Battery Backup Unit. Save the board extender for future use if you move the adapter to another system. Figure 5-1. Remove Board Extender Before Installing the Adapter in HP NetServer LXr Pro Systems Install Additional Memory For the HP NetRAID adapter, cache memory resides in a 4 MB battery-backed 60-ns FPM (Fast-Page Mode) DRAM SIMM.
Chapter 5 Installation and Configuration Connect Battery Backup Unit NOTE The HP NetRAID-1 adapter does not have a Battery Backup Unit. The HP NetRAID and HP NetRAID-3Si adapters are shipped with the Battery Backup Unit for the cache memory. The Battery Backup Unit is installed and charged, but disconnected. Follow the directions below for your specific adapter to connect the Battery Backup Unit.
Chapter 5 Installation and Configuration HP NetRAID On the HP NetRAID adapter, the Battery Backup Unit is the mezzanine board already installed on the HP NetRAID adapter. Do not remove the Battery Backup Unit from the HP NetRAID adapter. To connect the battery pack, plug the connector on the wire in the lower-left corner into the connector at J2 as shown in Figure 5-2. The connector is keyed to make sure the proper connection is made. Figure 5-2.
Chapter 5 Installation and Configuration HP NetRAID-3Si The Battery Backup Unit is a battery pack already installed on the HP NetRAID3Si adapter. Connect it, as described below, before installing the adapter in the HP NetServer. To connect the battery pack, plug the connector on the wire in the lower-left corner into the connector at J21, as shown in Figure 5-3. The connector is keyed to make sure the proper connection is made. Figure 5-3.
Chapter 5 Installation and Configuration Step D. Install the Adapter In this step, you will: • Turn off the HP NetServer and remove the covers • Install the adapter Turn Off the HP NetServer and Remove Cover NOTE Before you begin, you may need to look up information about your HP NetServer in Information Assistant on the HP NetServer Navigator CD-ROM.
Chapter 5 CAUTION Installation and Configuration Follow the procedures in your system's road map or in Information Assistant to successfully remove and replace the power supplies. Failure to follow these procedures may result in breaking the power management board. 5. To remove an existing adapter, disconnect its SCSI cables first. Install the Adapter CAUTION Do not allow the adapter to contact any part of the HP NetServer other than the PCI slot during installation.
Chapter 5 Installation and Configuration Step E. Install Cables and Set SCSI ID Switches In this step you connect the adapter's SCSI channels to the physical drives listed in Worksheet A and set their SCSI ID switches. Connect Cables and Set SCSI ID Switches Install the cables to create the hardware setup you planned in Worksheet A. See Appendix D for sample cabling diagrams and default switch settings.
Chapter 5 Installation and Configuration Note the cable requirements for the HP NetRAID-3Si: • The external connectors for Channels 0 and 2 on the HP NetRAID-3Si are very close together and require D6020A cables with offset connectors. Some nonstandard cable configurations and switch settings are listed in the HP NetServer user guides. Refer to the mass storage section of your system documentation for details on HP NetServer configurations. Use the lowest SCSI ID numbers first.
Chapter 5 CAUTION Installation and Configuration Handle disk modules carefully. They are more susceptible to shock, vibration, and electrostatic discharge when they are not in the cabinet. When removing a module while the system is powered on, disengage the module and wait for it to stop spinning before removing it from its hot swap shelf. Also, do not touch the SCSI edge connector pins. The oils on your skin could impair the electrical connection.

Chapter 5 Installation and Configuration To assign physical drives to an existing (not new) array: 1. Click one or more Ready physical drives to select (or deselect) them. 2. Drag the drives into the existing array. All selected Ready drives will be added to the array. Drives cannot be removed selectively from an existing array, but the entire array can be undone. An array cannot be reclaimed if it has any logical drives defined. To remove an entire array: 1. Select the array.
Chapter 5 Installation and Configuration Define Logical Drives NOTE Refer to Worksheet B when defining logical drives. After you finish defining arrays and hot spares, and click Next, the HP NetRAID Assistant Wizard Logical Drive Definition window appears. A sample window is shown in Figure 5-8. The window is ready for you to define Logical Drive 0. Figure 5-8.
Chapter 5 ◊ Installation and Configuration The Logical Devices box depicts the arrays on the current adapter, the logical drives on each array, and the global hot spare pool for the adapter. Logical drives are labeled as new and as LD0 through LD7. Click on the + sign in the yellow diamond if the view is collapsed (logical drives are hidden). The HP NetRAID Assistant Wizard is ready for you to set the parameters of the new logical drive. To define a logical drive that does not span arrays: 1.
Chapter 5 Installation and Configuration To create a logical drive that spans two or more arrays: 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.
Chapter 5 Installation and 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 5-9, displays the configuration proposed for the physical and logical drives. Figure 5-9.

Chapter 6 HP NetRAID Series Software Enable Power Fail Safeguard The Power Fail Safeguard feature lets you protect a disk array during the reconstruction process should a power failure occur. When you use this feature, a copy of the data currently being reorganized always remains on disk, so there is no risk of losing data. To enable the Power Fail Safeguard feature: 1. Choose Objects from the Tools Management menu. 2. Choose Adapter from the Objects menu. 3.
Chapter 6 HP NetRAID Series Software 5. Save the configuration; the system will reboot. For backup purposes, we recommend that you save the EISA configuration on a diskette. Refer to the host system documentation for instructions on how to do this. Run the Setup Utility For details of the Setup utility on your HP NetServer, refer to your system documentation. On most systems, you launch the Setup utility by restarting the HP NetServer and pressing the F2 function key when prompted.
7 Preparing for Online Capacity Expansion Step N. Prepare for Online Capacity Expansion The HP NetRAID Online Capacity Expansion feature allows you to add new storage capacity to drives controlled by an HP NetRAID Series adapter without rebooting the server. Online Capacity Expansion has these restrictions: • Online Capacity Expansion has a maximum capacity of 82 GB. Online Capacity Expansion is not available if your physical capacity exceeds 82 GB.
Chapter 7 Preparing for Online Capacity Expansion This chapter is divided into two sections: • See "Capacity Expansion Under Novell NetWare" if you are using Novell NetWare. • See "Capacity Expansion Under Windows NT" if you are using Microsoft Windows NT. Online Capacity Expansion Under Novell NetWare Theory of Operation 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.
Chapter 7 Preparing for Online Capacity Expansion Although undesirable, NetWare allows you to create volumes into the virtual space. This is because during volume creation, NetWare only looks at the beginning of the volume and if there is real storage space there, the volume will be created. However, when writing to this volume, you cannot write beyond the physical limit and write errors will be generated when the physical space is filled.
Chapter 7 Preparing for Online Capacity Expansion Preparing for Online Capacity Expansion This section describes how to enable Virtual Sizing and set up your partitions to permit easy capacity expansion. For NetWare installations, plan ahead and consider your storage use. Since NetWare permits only one NetWare partition per logical drive, make the NetWare partition the size of the virtual logical drive in advance so that you can expand that volume.
Chapter 7 Preparing for Online Capacity Expansion NOTE It is important to initialize your logical drives. If the drives have been previously configured under an operating system, there can sometimes be residual partition/format information which subsequently causes misrepresentation of logical drives under NetWare's Install module. • You already installed NetWare as discussed in Chapter 5. 1. Enable Virtual Sizing. 1.
Chapter 7 Preparing for Online Capacity Expansion 11. If you have multiple 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, then choose Yes. NOTE Clearing a previous configuration does not reset the Virtual Sizing setting for a logical drive.
Chapter 7 Preparing for Online Capacity Expansion for use. Be sure not to exceed the actual physical capacity when creating the 12-GB volume and include other uses such as a Hot Fix area. The new volume is now ready for use. Assume for this example, the volume is called VOL1. Leave the remaining virtual storage space (81,917 MB minus 12 GB) as unused. You can write data up to 12 GB on the drive.
Chapter 7 NOTE Preparing for Online Capacity Expansion The additional capacity will have a different drive letter than the original logical drive. If the expanded capacity and the original capacity must share the same drive letter, you cannot expand capacity online and you must reboot NT. For more information about drive letters, see "Capacity Expansion" in the HP NetRAID Series User Guide in Information Assistant. Capacity Expansion is enabled separately on each logical drive.
Chapter 7 Preparing for Online Capacity Expansion Setting Up Your Array for Capacity Expansion This section makes the following assumptions: • You have already installed your drives and configured your adapter as discussed in Chapter 4. You should have created only one logical drive per array. For example, you might have four physical drives of 4 GB each connected to the adapter. You might have configured these four drives as a single RAID 5 logical drive.
Chapter 7 Preparing for Online Capacity Expansion 6. From the Logical Drive 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 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 Partition and Format Drives that do not Contain Windows NT Follow these instructions for drives that do not contain Windows NT. 1. Create a partition equal to (or less than) the real storage capacity. In our ongoing example, you would create a 12 GB partition. NOTE If you try to create a partition that is larger than the real storage capacity, the format operation will generate this message: Warning: NT was unable to complete the format. 2.
8 Upgrading to an HP NetRAID-3Si Adapter This chapter explains how to replace an existing adapter with an HP NetRAID3Si adapter. When you replace one adapter with another, you do not need to worry about data compatibility. Data created using any HP NetRAID Series adapter is compatible with any other HP NetRAID Series adapter. Further, data created using HP NetRAID non-I2O drivers is compatible with an adapter using I2O drivers.
Chapter 8 Upgrading to an HP NetRAID-3Si Adapter 2. Use the HP NetServer Navigator CD-ROM to prepare the diskettes you need to install the non-I2O drivers and the HP NetRAID configuration utility specific to your NOS.

Chapter 11 Troubleshooting Common Problems Without NetRAID Assistant, the client(s) and server(s) connect normally, but the NetRAID Assistant cannot connect to any servers For NetRAID Assistant to connect to a server, it must resolve the server via TCP/IP. Ping the server by name from the client or server that will run HP NetRAID Assistant. If this is unsuccessful, then the client or server that will run HP NetRAID Assistant cannot resolve the server using TCP/IP.
12 Warranty and Support The hardware warranty below applies to components purchased as accessories. If your component was factory-installed as part of an HP NetServer model, refer to the warranty statement provided with your system documentation. Hardware Warranty This HP NetServer accessory is covered by a limited hardware warranty for a period of one year from receipt by the original end-user purchaser.
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 HP NetRAID Series adapters 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. Array Spanning: Array spanning by a logical drive combines storage space in two, three, or four arrays of disk modules into the logical drive’s single contiguous storage space.
Glossary 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 adapter. Format: The process of writing zeros to all data fields in a physical drive (hard drive) and to map out unreadable or bad sectors. Because most hard drives are factory formatted, formatting is usually only done if a hard disk generates several media errors.
Glossary pass a Consistency Check. Arrays work without initializing, but they may fail a Consistency Check because parity fields may not have been generated. Logical Drive: A virtual drive within an array, which may consist of more than one physical disk. Logical drives divide up the contiguous storage space of an array of disk modules or a spanned group of arrays of disks. The storage space in a logical drive is spread across all the disks in the array or spanned arrays.
Glossary the system. If a single disk fails, it can be rebuilt from the parity of the respective data on the remaining disks. Physical Disk Roaming: The ability of an adapter to keep track of a hot swap disk module that has been moved to a different slot in the hot swap cages. Both slots must be controlled by the same adapter.
Glossary • 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. • RAID 10 results when a RAID 1 logical drive spans arrays. • RAID 30 results when a RAID 3 logical drive spans arrays. • RAID 50 results when a RAID 5 logical drive spans arrays.
Glossary 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. • Online: a powered-on and operational disk that has been configured. • Hot Spare: a powered-on, stand-by disk ready for use should a disk fail. • Not Responding: the disk is not present, not powered-on, or has failed. • Failed: errors on the disk have caused it to fail, or you have used an HP NetRAID utility to take the drive offline.
Glossary Write Policy: When the processor writes to main memory, the data is first written to the cache on the assumption that the processor will probably read it again soon. The two Write policies for HP NetRAID are: • Write Back: In a write-back cache, data is written to main memory only when it is forced out of the cache. Write-back requires the cache to initiate a main memory write of the flushed entry, followed (for a processor read) by a main memory read.
