1 Introduction Overview This manual describes how to install, set up, and use the FCArray Assistant Client/Server software on HP NetServers using Microsoft’s Windows NT 4.0 Workstation and Server operating systems. The FCArray Assistant software is delivered on the CD-ROM accompanying the hardware. However, diskettes must be created to install the software. Refer to Chapter 2, "FCArray Assistant Software Installation," for Server and Client installation, respectively.
Chapter 1 Introduction Figure 1-1. FCArray Assistant Client Monitoring Functions The FCArray Assistant Server software collects and disseminates information on disk array status and resource utilization. If the goal is monitoring and simple maintenance or messaging, FCArray Assistant Server is sufficient for these tasks. The FCArray Assistant Client software, an additional component available from Hewlett-Packard, accesses this information and then organizes it through an intuitive graphical display.
Chapter 1 Introduction The RAID Assistant is an intuitive, wizard-like utility that can automatically configure the disk arrays. In Automatic Configuration mode, the utility operates interactively with the user to answer a few simple questions and then automatically configures the disk arrays. The Assisted Configuration and the Manual Configuration modes provide more control over drive group setup or individual configuration parameters.
Chapter 1 Introduction ensure a successful installation. The FCArray Assistant software is delivered on the CD-ROM accompanying the hardware.
Chapter 1 Introduction Client Software • Appropriate network drivers for the installed network interface card • An installed and functioning FCArray Assistant Server software component on at least one server on the network, under Windows NT 4.0, is required to install the FCArray Assistant Client software component • Microsoft Windows NT 4.
2 FCArray Assistant Software Installation Software Preparation The HP NetServer Navigator CD-ROM is run on the HP NetServer to create the diskette(s) used to install the FCArray Assistant software. After the diskettes are created, the HP NetServer Navigator CD-ROM is no longer needed. The diskette(s) are then used to install the FCArray Assistant software from within Windows NT 4.0, on both the managed server and the remote management workstation.
Chapter 2 FCArray Assistant Software installation software updates since the creation of the CD-ROM and indicates if updates are required and how to obtain the updates. Each version of the CD-ROM has a four-digit Document Number printed on the disk. Obtain the Status Report for the CD-ROM in one of the following ways: • FAX: Call HP’s FAX system at 1-800-333-1917 (or 1-208-344-4809 from your FAX machine).

Chapter 4 Configuration NOTE For a Simplex controller configuration it is important to duplicate the entries on Controller 0/Port 0 and Controller 0/Port 1. See Figure 4-45. For a Dual Active controller configuration, the load should be balanced across the two controllers. In the event of a failure to either controller, the surviving controller will activate its failover port and transparently take over the workload of the failed controller. See Figure 4-46. 1.
Chapter 4 Configuration Figure 4-45. LUN Mapping in Simplex Mode Consider the following points. ◊ The Clear All button sets all LUN assignments to None. You can then select individual assignments more closely while allowing several assignments of "inaccessible." WARNING DO NOT leave all assignments at None. This indicates there are no logical drives accessible to any port on any controller. ◊ The Set Sequential button sets all LUN assignments sequentially on all available ports.
Chapter 4 Configuration ◊ The Cancel button cancels the entire configuration, including what was set up under the Disk Arrays, Logical Drives, and LUN Mapping tabs. NOTE HP requires LUN 0 on each active port, however, the order and value of LUNs on each port is flexible. See Figures 4-45 and 4-46 for examples. Figure 4-46. LUN Mapping in Dual Active Mode 6. Click Apply when ready to accept the entire RAID Controller configuration you’ve specified across all Manual Configuration tabs.
Chapter 4 Configuration Special Features in Manual Configuration This section describes the special features only available in RAID Assistant’s Manual Configuration.

This option is only available in Manual Configuration mode. See Figure 4-48 1. Click RAID Assistant.. in the Administration menu, to access the Expand Array function. See Figure 4-47. Figure 4-47.
Chapter 4 Configuration Figure 4-48. Accessing Manual Configuration Button The Manual Configuration Dialog box appears. See Figure 4-49. Figure 4-49.
Chapter 4 Configuration 4. If the Expand Array button is gray and cannot be selected, one of the following conditions exist: a. There are no arrays to expand. b. All of the existing arrays have the maximum permissible number of drives. c. There are no un-configured drivers available. d. The FCArray Controllers are operating in a Dual-Active configuration. If the FCArray Controllers are operating in Dual-Active mode, you will need to temporarily operate in failover mode to expand an array.
Chapter 4 Configuration ◊ Add Logical Drive (or Add LUN) - This option adds additional physical drives in an existing single or multiple LUN array. It may also be used to add new logical drives to increase the number of LUN arrays. The RAID level of the existing Logical Drives may change to accommodate re-striping. The existing array can not be spanned or contain more than 7 physical drives and must contain only one logical drive. Data integrity is maintained during this process. 7.

6 Maintenance Processes Introduction FCArray Assistant Client maintenance processes include the activities listed below. These activities may be required occasionally to maintain arrays that use redundancy and/or fault tolerance, or to maintain the most up-to-date firmware maintenance releases: • Running a consistency check on a logical drive to examine (and optionally restore) consistency (parity). Encountered errors may be written to the Error Table.
Chapter 6 Maintenance Processes Figure 6-1. Controller View Selection The Controller View window appears on screen. See Figure 6-2. 2. Double-click the desired logical drive in Controller View window. The logical drives are located on the right side of the Controller View window. The Logical Drive Information dialog box appears on screen. See Figure 6-3. Figure 6-2.
Chapter 6 Maintenance Processes 3. Click the Consistency Check button in the Logical Drive Information dialog box. See Figure 6-3. Figure 6-3. Logical Drive Information Dialog Box A message is displayed asking if you would like consistency restored in the event of errors. See Figure 6-4. 4. Click No if you just want to carry out the consistency check. There is no risk of data loss if No is selected. Errors will still be reported to the Error Table, but no attempt will be made to correct them.
Chapter 6 Maintenance Processes Figure 6-4. Consistency Check Error Action Message Consistency Check starts and the Consistency Check Status box appears. See Figure 6-5. Figure 6-5. Consistency Check Status Box 6. Close the Logical Drive Information dialog box and continue, or leave the dialog box open until Consistency Check has completed.
Chapter 6 Maintenance Processes If you need to carry out a device rebuild, perform the following procedure: 1. Reinsert the original drive responsible for the failure, unless it has failed. 2. Or, replace the failed drive with a new drive of equal or greater capacity. 3. Double-click the relevant physical device in the Controller View window. See Figure 6-6. Figure 6-6.

A Error Codes Overview FCArray Assistant classifies the events it records into five severity levels described in the following table. Table A-1. Severity Level Priorities and Descriptions Severity Type Description 0 Critical Controller failure. 1 Serious The failure of a major component within the array enclosure. For example, a power supply, fan or physical drive. 2 Error A consistency check fails, or a rebuild on a drive stopped because of errors.
Appendix A Error Codes 272 Power supply failure. 274 Power supply failure. 288 Over temperature. Temperature is above 70 degrees Celsius. 291 Over temperature. 517 Lost connection to server, or server is down. Errors (Level 2) 9 Rebuild stopped with error. 10 Rebuild stopped with error. New device failed. 11 Rebuild stopped because logical drive failed. 18 Expand Capacity Stopped with error. 131 Consistency check on logical drive error. 132 Consistency check on logical drive failed.
Appendix A Error Codes 389 Controller has been reset. 393 Battery Power Low. 399 Controller’s partner is gone; controller is in failover mode now. Information (Level 4) 1 A hard disk in array changed status. 2 A hard disk been added as hot spare. 5 An automatic rebuild has started. 6 A manual rebuild has started. 7 Rebuild is over. 8 Rebuild is cancelled. 13 A new physical device has been found. 14 A physical device has been removed.
Appendix A Error Codes 144 Logical drive initialization started. 145 Logical drive initialization done. 146 Logical drive initialization cancelled. 148 A new logical drive has been created. 149 A logical drive has been deleted. 150 Expand Capacity Started. 151 Expand Capacity Completed. 153 Bad Blocks found. 154 System drive size changed. 155 System drive type changed. 257 Fan has been restored. 259 No Message. 273 Power supply has been restored. 275 No Message.
B Glossary Active/Active Mode See "Dual-Active (Duplex) Mode." BBU See "Battery Backup Unit." Bad Block Table (or Bad Data Table) There are two bad-block tables that the controller automatically maintains. The Rebuild Bad Block Table stores information on bad blocks encountered during a rebuild or consistency check process. The Write-Back Bad Block Table stores information on all irrecoverable write-back errors that occur.
Appendix B Glossary Consistency Check Refers to a process where the integrity of redundant data is verified. For example, a consistency check of a mirrored drive will make sure that the data on both drives of the mirrored pair is exactly the same.
Appendix B Glossary Dual-Active (Duplex) Mode This is a method of interconnecting multiple RAID controllers that share a common set of drives. In addition to increasing overall performance, this method allows a surviving controller to take over resources of a failed controller. This "failover" process is transparent to the host. Duplex Mode See "Dual-Active (Duplex) Mode." Error Table See "Bad Block Table (or Bad Data Table).
Appendix B Glossary assignments are per host port and are independent of the assignments on other host ports. Logical drives may be assigned only one LUN per host port. By not assigning a LUN to a logical drive on a particular host port, that logical drive is made inaccessible to that host port. Logical Drive States The state of a logical (system) drive can be either ONLINE, CRITICAL, or OFFLINE. Notice that the same term "online" is used for both physical and logical drives.
Appendix B Glossary Mirroring Refers to the 100% duplication of data on one disk drive to another disk drive. Each disk will be the mirror image of the other. Pack See "Drive Groups (or Drive Packs)." Parity See "Rotated XOR Redundancy." Physical Drive States Refers to a drive’s current operational status. At any given time, a drive can be in one of four states: ONLINE, STANDBY, DEAD, or REBUILD. The controller stores the state of the attached drives in its non-volatile memory.
Appendix B Glossary Rebuild: A disk drive is in a “rebuild” state... While it is in the process of being rebuilt. During this process, data is regenerated and written to the disk drive. This state is sometimes referred to as "Write-Only" (WRO). RAID RAID stands for Redundant Array of Independent Disks. Several different forms of RAID implementation have been defined. Each form is usually referred to as a "RAID level.
Appendix B Glossary Level 5 Data is "striped" across several physical drives. For data redundancy, drives are encoded with rotated XOR redundancy. Level 0+1 Combines RAID 0 striping and RAID 1 mirroring. This level provides redundancy through mirroring. Levels 00, 10, 30, and 50 Multi-layer RAID levels, which span RAID levels 0, 1, 3, and 5 by striping data across, drive groups (RAID Drives). JBOD Sometimes referred to as "Just a Bunch of Disks.
Appendix B Glossary Replacement Table A replacement table contains information regarding which devices have been replaced by others through standby replacement. Rotated XOR Redundancy This term (also known as "parity" or "consistency data") refers to a method of providing complete data redundancy while requiring only a fraction of the storage capacity of mirroring.
Appendix B Glossary • A "standby" disk drive of identical or larger size is found attached to the same controller. • All of the system drives that are dependent on the failed disk are redundant system drives, for example, RAID 1, RAID 3, RAID 5, and RAID 0+1. NOTE The automatic rebuild will only happen on the SAME controller, never across controllers. A "Hot Spare" disk can be created in one of two ways: a.
Appendix B Glossary into blocks. Block 1 of the data will be stored on drive 1, block 2 on drive 2, block 3 on drive 3, block 4 on drive 1, block 5 on drive 2 and so on. This storage method increases the disk system throughput by ensuring a balanced load among all drives. System Drive Affinity See "LUN Mapping." System Drives See "Logical Drives." Target ID A target ID is the ID of a device attached to a controller.
