1 Installing and configuring AIX 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.
Even though the interface is Fibre Channel, this guide uses the term “SCSI disk” because disk array devices are defined to the host as SCSI disks. Device emulation types The XP family of disk arrays and the SVS200 support 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. Supported emulations include OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.
Figure 1 SNMP configuration XP RAID Manager command devices HP StorageWorks XP RAID Manager manages HP StorageWorks XP Business Copy Software or HP StorageWorks XP Continuous Access Software operations from a host server. To use XP RAID Manager you must designate at least one LDEV as a command device. This can be done with XP Remote Web Console, XP Command View (XP arrays only), or Command View XP Advanced Edition Software to .
• Installing and formatting devices After these tasks are finished, you will use XP Remote Web Console, XP Command View (XP arrays only), Command View XP Advanced Edition Software, or XP Array Manager to complete the remaining tasks listed below. If you do not have these programs, your HP service representative can perform these tasks for you.
The following host group mode is available for AIX: Table 2 Host group mode (option) Host Group Mode 2 Function Default Comments VERITAS® Storage Foundation for Oracle RAC, DBE+RAC Database Edition/Advanced Cluster for Real Application Clusters or if VERITAS® Cluster Server 4.0 or later with I/O fencing function is used. Inactive Previously MODE186 Do not apply this option to Sun Cluster.
Fibre address In fabric environments, the port addresses are assigned automatically. In arbitrated loop environments, set the port addresses by selecting a unique arbitrated loop physical address (AL-PA) or loop ID for each port. For specific values, refer to the HP StorageWorks XP LUN Manager User's Guide applicable to your array. Fabric and connection parameter settings Set each array port to FABRIC ON or OFF with connections of POINT-TO-POINT or FC-AL as shown in the following figure and table.
Fabric Parameter Connection Parameter Provides ON Point-to-Point F-port (fabric port) OFF FC-AL NL-port (private arbitrated loop) OFF Point-to-Point Not supported Installing and configuring the host This section explains how to install and configure the host and host bus adapters (HBAs) that connect the host to the disk array. Loading the operating system and software Follow the manufacturer's instructions to load the operating system and software onto the host.
Figure 3 Multi-cluster environment Within the Storage Area Network (SAN), the clusters may be homogeneous (all the same operating system) or they may be heterogeneous (mixed operating systems). How you configure LUN security and fabric zoning depends on the operating system mix and the SAN configuration.
Defining the paths Use XP Remote Web Console (shown), XP Command View (XP arrays only), or Command View XP Advanced Edition Software to define paths (LUNs) between hosts and volumes in the disk array. This process is also called “LUN mapping.
#lsdev -Cc disk hdisk0 Available 10-60-00-5, 0 16 Bit SCSI Disk Drive hdisk1 Available 10-60-00-6, 0 16 Bit SCSI Disk Drive The example shows that Device hdisk0 is installed on bus 60 and has TID=5 and LUN=0. 4. Record the device file names for the new devices. You will use this information in changing the device parameters. 5. Use the lscfg command to find out the AIX disk device's corresponding array LDEV designation.
The recommended queue depth settings may not provide the best I/O performance for your system. You can adjust the queue depth setting to optimize the I/O performance of the disk array. Displaying the device parameters using the AIX command line At the command line prompt, enter lsattr -E -l hdiskx, where hdiskx is the device file name. Example # lsattr –E -l hdisk2 Changing the device parameters using the AIX command line 1. To change the R/W timeout parameter, enter: chdev –1 hdisk x 2.

2 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.
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 HBA and make sure it was installed properly. Reboot the host. The host hangs or devices are declared and the host hangs.

Note 3: 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.
Example 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 6: 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 Command View XP Advanced Edition Software.

Example When 37 MB is specified for the OPEN-3 CVS volume and the four volumes are concatenated, the number of cylinders of the OPEN-3 CVS can be calculated as follows: 37 × 1,024 / 720 × 4 = 52.62 × 4 = 53 × 4 = 212 The LUSE for the OPEN-3 CVS volume has 212 cylinders. Byte information table Values in this table assume that large files are stored in large volumes, and the maximum number of files stored in each device type is approximately the same for each device type.

Glossary AL Arbitrated loop. 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).
host mode Each port can be configured for a particular host type. These modes are represented as two-digit hexadecimal numbers. For example, host mode 08 represents an HP-UX host. LDEV Logical device. An LDEV is created when a RAID group is carved into pieces according to the selected host emulation mode (that is, OPEN-3, OPEN-8, OPEN-L). 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.
component separated by a colon. For example 00:00 and 01:00 are two uniquely identified volumes; one is identified as CU = 00 and LDEV = 00, and the other as CU = 01 and LDEV = 00; they are two unique separate virtual storage devices within the XP array. VSC Volume size customization. Synonymous with CVS. WWN World Wide Name. A unique identifier assigned to a Fibre Channel device.
