About this guide
1 Installing and configuring Novell Netware for the XP disk array You and your HP service representative each play a role in installation. Your HP service representative is responsible for installing the disk array and formatting the disk devices. You are responsible for configuring the host server for the new devices with assistance from your HP service representative. Features and requirements Ask your HP service representative about the latest supported hardware and software.
Device emulation types The XP family of disk arrays supports these device emulation types: • OPEN-x devices: OPEN-x logical units represent disk devices. Except for OPEN-V, these devices are based on fixed sizes. OPEN-V is a user-defined size based on a CVS device. Supported emulations include OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.
Figure 1 SNMP configuration Installation roadmap Perform these actions to install and configure the disk array: 1. Installing and configuring the disk array 2. • Setting the host mode and host group mode for the disk array ports • Setting the System Option Modes • Configuring the Fibre Channel ports Installing and configuring the host 3.
Setting the host mode and host group mode for the disk array ports After the disk array is installed, you must set the host mode for each disk array port to match the host OS. Set the host mode using LUN Manager in XP Remote Web Console (shown), XP Command View, or XP Command View Advanced Edition Software. If these are not available, the HP service representative can set the host mode using the SVP. The host mode setting for Novell Netware is 0A.
CAUTION: Changing host group modes for ports where servers are already installed and configured is disruptive and requires the server to be rebooted. Setting the System Option Modes The HP service representative sets the System Option Mode(s) based on the operating system and software configuration of the host. Notify your HP representative if you install storage agnostic software (such as backup or cluster software) that may require specific settings.
connected by a fabric switch. Also, you must specify FC-AL or point-to-point in the “Mode” field of the Change Port Mode pane. The default is FC-AL. If you are using a fabric switch, consult the switch's documentation to determine whether FC-AL or point-to-point should be used. Some fabric switches require that you specify point-to-point to get the system running. For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide at: http://www.hp.com/go/sandesign.
NetWare Client software is required for the client system. After installing the software on the NetWare server, follow these steps: 1. Open the Novell Client Configuration dialog and click the Advanced Settings tab. 2. Change the following parameters: Give up on Requests to Sas: 180 Net Status Busy Timeout: 90 Configuring NetWare ConsoleOne NetWare 6.x Novell NetWare v6.x requires a tool called ConsoleOne to work in a storage environment.
Figure 3 Multi-cluster environment Within the Storage Area Network (SAN), the clusters must be homogeneous (all the same operating system). Heterogeneous (mixed operating systems) clusters are not allowed. How you configure LUN security and fabric zoning depends on the SAN configuration. Fabric zoning and LUN security for multiple operating systems You can connect multiple clusters with multiple operating systems to the same switch and fabric using appropriate zoning and LUN security.
Defining the paths Use XP Remote Web Console (shown), XP Command View (XP arrays only), or XP Command View Advanced Edition Software to define paths (LUNs) between hosts and volumes in the disk array. This process is also called “LUN mapping.

Record the device number for each new device on the worksheet in “Path Worksheet” on page 33. This information will be useful later during disk partitioning and volume creation. 4. Verify that all new disk devices are listed. Configuring disk devices Configure the disks in the disk array using the same procedure for configuring any new disk on the host.
9. Select Create NetWare disk partition again, and press Enter. 10. When the “Create NetWare Partition?” message appears, click Yes and press Enter to create the specified disk partition on the selected device. 11. Press Esc until you are returned to the Available Devices screen. Repeat steps 4 through 10 to create the disk partition on each new OPEN-x and LUSE device. 12.
3. Press Insert, then select a device where you want to create a partition. 4. Select “NSS” as the partition type. 5. Enter the size of the partition in bytes (B), kilobytes (KB), megabytes (MB), or gigabytes (GB) and click OK. Assigning the new devices to volumes A volume can span as many as 32 devices, so you can assign more than one device to a volume. The addition of new volumes to the NetWare server may require a memory upgrade. See the NetWare documentation or contact Novell customer support.
4. On the Create Logical Volume – Storage Information screen, select the desired pool/device, enter the desired Volume Quota, and click Next. 5. After you have created the pool, select Activate and Mount in the On Creation box, and then click Finish. NetWare 6.5 1. Enter NSSMU at the server console 2. In the main menu, select Pools. 3. Press Insert and enter a name for the new pool. 4. Select Activate and Mount in the On Creation box as desired. 5.
7. Map the created Logical Volume as the Network Drive. 8. Confirm the mapped drive. Netware 6.5 1. Enter NSSMU at the server console. 2. In the main menu, select Volumes. 3. Press Insert and enter a name for the new volume, then click Next. 4. Select the desired pool/device, enter the desired Volume Quota, then click Next. 5. Review and change volume attributes as necessary. 6. Select Create.
2 Middleware configuration The disk array supports many industry-standard middleware products which provide host failover and logical volume management. Available host failover products for the Novell NetWare server operating system include the Novell High Availability Server (NHAS), SFT III software products, Novell Clustering Services, and Novell Multipath Support.
3. Restart the server. 4.
MM Reset failover registry This command will delete all the failover entries in the registry, and recreate them again based on the current set of failover devices. As a path fails, it is automatically marked as a Down (offline) path, and the next highest priority path is automatically selected. When the device is reactivated, the state is automatically reset to an Up (online) state, and again the highest priority path is selected. Use the NWCONFIG NetWare utility to create partitions/Volumes for each LUN.
Click Browse. Highlight all of the servers that you want to add and click Add to Cluster. You may use the shift and control keys to select multiple nodes. After all servers in the cluster appear on the list, click Next. Wait while NWDeploy accesses each node. After all services have been accessed and added to the “NetWare Servers in Cluster” list, click OK. 7. Enter a unique IP address for the Master_IP_Address_Resource (for example, 10.1.1.5) in the Cluster IP Address Selection window and click Next. 8.
3. Press Insert and enter a name for the new volume, then click Next. 4. Select the desired pool/device, enter the desired Volume Quota, then click Next. 5. Review and change volume attributes as necessary. 6. Select Create.

3 Troubleshooting This section includes resolutions for various error conditions you may encounter. If you are unable to resolve an error condition, ask your HP support representative for assistance. See “Calling the HP support center” on page 32. Error conditions Depending on your system configuration, you may be able to view error messages (R-SIMS) as follows: • In XP Remote Web Console (Status tab) • In XP Command View Advanced Edition Software (“Alerts” window).
Error Condition Recommended Action The disk array performs a self reboot because the disk array was busy or it logged a panic message. Reboot the host. The disk array responds “Not Ready” or the disk array has displayed “Not Ready” and timed out. Contact HP. The host detects a parity error. Check the FCA and make sure it was installed properly. Reboot the host. The host hangs or devices are declared and the host hangs.

B Disk array supported emulations This appendix provides information about supported emulations and emulation specifications. Some parameters may not be relevant to your array. Consult your HP representative for information about supported configurations for your system. Supported emulations HP recommends using OPEN-V as the emulation for better performance and features that may not be supported with the legacy emulations (OPEN-[389LE]).
Emulation (Note 1) Category (Note 2) Product name (Note 3) Blocks (512 bytes) Sector size (bytes) OPEN-3*n SCSI disk OPEN-3*n 4806720*n 512 OPEN-8*n SCSI disk OPEN-8*n 14351040*n OPEN-9*n SCSI disk OPEN-9*n OPEN-E*n SCSI disk OPEN-L*n # of Cylinders Heads Sectors per track Capacity MB* (Note 4) 3338*n 15 96 2347*n 512 9966*n 15 96 7007*n 14423040*n 512 10016*n 15 96 7042*n OPEN-E*n 28452960*n 512 19759*n 15 96 13893*n SCSI disk OPEN-L*n 71192160*n 512 49439*
Note 3: The command device (used for XP Raid Manager) is distinguished by -CM on the product name (for example, OPEN-3-CM, OPEN-3-CVS-CM). Note 4: The device capacity can sometimes be changed by the BIOS or host adapter board. This may make actual capacity different from that listed in the table.
For an OPEN-V CVS LUSE volume with capacity = 49 MB and n = 4: # of cylinders = 49 × 16/15 × 4 = 52.26 × 4 = 53 × 4 = 212 Note 7: The capacity of an OPEN-3/8/9/E CVS volume is specified in MB, not number of cylinders. The capacity of an OPEN-V CVS volume can be specified in MB or number of cylinders. You set the volume size using XP Remote Web Console, XP Command View (XP arrays only), or XP Command View Advanced Edition Software.
Glossary AL-PA Arbitrated loop physical address. array group A group of 4 or 8 physical hard disk drives (HDDs) installed in an XP disk array and assigned a common RAID level. RAID1 array groups consist of 4 (2D+2D) or 8 HDDs (4D+4D). RAID5 array groups include a parity disk but also consist of 4 (3D+1P) or 8 HDDs (7D+1P). All RAID6 array groups are made up of 8 HDDs (6D+2P).
OPEN-E). The number of resulting LDEVs depends on the selected emulation mode. The term LDEV is often used synonymously with the term volume. LUN Logical unit number. A LUN results from mapping a SCSI logical unit number, port ID, and LDEV ID to a RAID group. The size of the LUN is determined by the emulation mode of the LDEV and the number of LDEVs associated with the LUN. For example, a LUN associated with two OPEN-3 LDEVs has a size of 4,693 MB.
VSC Volume size customization. Synonymous with CVS. WWN World Wide Name. A unique identifier assigned to a Fibre Channel device. XP Command View Advanced Edition Software HP StorageWorks XP Command View Advanced Edition Software, installs on the user-provided Device Manager server and provides a browser-based platform from which you can manage the SVS 200 and the XP family of disk arrays—even globally distributed arrays.
