Preface
1 Installation 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. The disk array has the following features: • Storage capacity.
HP HP HP HP StorageWorks StorageWorks StorageWorks StorageWorks Cache LUN XP Auto Path XP Cluster Extension XP Performance Advisor XP Fibre Channel interface The XP family of disk arrays supports these Fibre Channel elements: • • • • • Connection speed of 1 Gbps and 2 Gbps Short-wave non-OFC (open fiber control) optical interface Multimode optical cables with SC or LC connectors Public or private arbitrated loop (FC-AL) or direct fabric attach Fibre Channel switches Even though the interface is Fibre C
SNMP configuration The XP family of disk arrays supports standard Simple Network Management Protocol (SNMP) for remotely managing the disk array. The SNMP agent on the SVP performs error-reporting operations requested by the SNMP manager. SNMP properties are usually set from the SVP but they can also be set remotely using Remote Web Console XP, Command View XP, or Command View XP Advanced Edition. Refer to the applicable user's guide for procedures.
Installation procedures Perform these actions to install and configure the disk array: 1. Install and configure the disk array • Setting the System Option Modes • Configuring the Fibre Channel ports • Setting the host mode for the disk array ports 2. Install and configure the host • Loading the OS and software • Installing and configuring the HBAs • Clustering and fabric zoning • Fabric zoning and LUN security for multiple operating systems 3.
Install and configure the disk array The HP service representative performs these tasks: • Assembling hardware and installing software • Loading the microcode updates • Installing and formatting devices After these tasks are finished, you will use Remote Web Console, Command View, Command View XP Advanced Edition, or LUN Configuration and Security 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.
Configuring the Fibre Channel ports Configure the disk array Fibre Channel ports by using Remote Web Console (shown), Command View, or Command View XP AE. Select the settings for each port based on your storage area network topology. Use switch zoning if you connect different types of hosts to the array through the same switch. Fibre Address In fabric environments, the port addresses are assigned automatically.
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 table and figures. For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide on the http://www.hp.com website.
Setting the host 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 Remote Web Console XP (shown), Command View XP, or Command View XP Advanced Edition. If these are not available, the HP service representative can set the host mode using the SVP. The host mode setting for SGI IRIX is 00.
For the XP1024/XP128 arrays, the host mode can also be set at the port information window in Command View XP AE.
Install and configure 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 OS and software Follow the manufacturer's instructions to load the operating system and software onto the host. Load all OS patches and configuration utilities supported by HP and the HBA manufacturer. Installing and configuring the HBAs Install and configure the host bus adapters using the HBA manufacturer's instructions.
Clustering and fabric zoning If you plan to use clustering, install and configure the clustering software on the servers. Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node. Multiple clusters compose a multi-cluster environment. The following example shows a multi-cluster environment with three clusters, each containing two nodes. The nodes share access to the disk array.
Fabric zoning and LUN security for multiple operating systems You can connect multiple clusters of various operating systems to the same switch and fabric using appropriate zoning and LUN security as follows: • Storage port zones may overlap if more than one operating system needs to share an array port. • Heterogeneous operating systems may share an XP array port if you use Secure Manager and set the appropriate host group and mode. All others must connect to a dedicated XP array port.
Connect the disk array The HP service representative connects the disk array to the host by: 1. Verifying operational status of the disk array channel adapters, LDEVs, and paths. 2. Connecting the Fibre Channel cables between the disk array and the fabric switch or host. 3. Verifying the ready status of the disk array and peripherals. Defining the paths Use Remote Web Console (shown), Command View, or Command View XP AE to define paths (LUNs) between hosts and volumes in the disk array.
In Command View XP AE, LUN mapping includes: • Configuring ports • Creating storage groups • Mapping volumes and WWN/host access permissions to the storage groups For details see the LUN Configuration and Security Manager User's Guide or the Command View XP Advanced Edition Device Manager Web Client User's Guide. Note the LUNS and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device configuration.
Verifying new device recognition To verify the devices on the newly installed disk array: 1. Power on the system. 2. Log in to the system as root. 3. Generate a file containing peripheral device information by entering # hinv –v > /tmp/hinv.info 4. Display peripheral device information by entering # more /tmp/hinv.info 5. Verify that all new devices on the disk array are listed.
Configure disk array devices Disks in the disk array are configured using the same procedure for configuring any new disk on the host. This includes the following procedures: 1. Creating device files 2. Partitioning and labeling the devices 3. Enabling command tag queuing 4. Creating the file systems 5. Creating and verifying the mount directories 6.
The pport# and nodename parameters are used to indicate the worldwide name (WWN) and the device port number (Fibre Channel disks have two ports). The vh and vol devices are in the rdsk directory only, because they are normally used only for ioctl and raw access. Fabric switch When the fabric switch is used, the WWN information is displayed by the nsShow command. The PortName (column 4) is the WWN, and the NodeName is the device port number.
Example # cd /dev # ./MAKEDEV dks find dsk rdsk \( -name ‘dks*d*s[0167]*’ -o -name ‘dks*d*s15*’ \ -o -name ‘dks*d*vol*’ -o -name ‘dks*d*vh*’ \) -print | xargs rm -rf umask 077; \ B_DKS=128; C_DKS=128; \ B_RAD=176; C_RAD=176; \ export B_DKS C_DKS B_RAD C_RAD; \ for NAME in ‘ls -1 MAKEDEV.d/DKS_* | grep -v ‘.[ON]$’‘ ; do \ $NAME ; \ done 3. Verify that the system has created the device files correctly, go to the /dev/dsk directory by entering: # cd /dev/dsk 4.
Partitioning and labeling the devices After new device recognition has been verified, partition the new SCSI disk devices using the fx utility. When the disk array is connected through a fabric switch, you must specify the device file when starting the fx utility. After setting the partitions for a device, verify the partitions using the prtvtoc command. The IRIX system controls disk devices using partitions. One LUN can be divided into a maximum of sixteen partitions (primary partition 0 through 15).
# fx –x Press Enter to label a disk. fx: "device-name" = (dksc) Enter the SCSI controller #. fx: ctlr# = (0) 8 Enter the SCSI TID. fx: drive# = (1) 0 Enter the LUN #. fx: lun# = (0) 15 ...opening dksc(8,0,15) ...drive selftest...OK OPEN-3 5244 Scsi drive type == HITACHI ----- please choose one (? For help, .. to quit this menu)----[exi]t [d]ebug/ [l]abel/ [a]uto [r]epartition/ [b]adblock/ [exe]rcise/ Enter r for partition menu.
CAUTION: Do not change partitions 8, 9, or 10. Set the partitions (except partition 10) so as not to partition on top of another partition. Because partition 8 usually uses parts between 0 and 6, set the base of the first partition to 6. Fibre Channel For connecting to a fabric switch, specify the device file directly: # fx -x -d /dev/rdsk/50000e10ff809999/lun2vol/ c8p50000e10ff809999 Example fx version 6.5, Jan 11, 2000 ...opening /dev/rdsk/50000e10ff809999/lun2vol/c8p50000e10ff809999 ...drive selftest...
Enabling command tag queuing SCSI command tag queuing must be enabled to optimize the performance of the disk array devices. Because command tag queuing is disabled by default in IRIX, you must enable it and set the queue depth for each disk array logical device (including Data Exchange devices) using the fx utility.
Example # fx -x "dksc(8,0,2)" fx version 6.5, Jan 11, 2000 ...opening dksc(8,0,2) ...drive selftest...OK fx: Warning: invalid label from disk driver, ignored OPEN-3-CVS 5244 Scsi drive type == HITACHI ...creating default bootinfo ...created default partitions, use /repartition menu to change ...creating default volume directory ----- please choose one (? for help, .. to quit this menu)----[exi]t [d]ebug/ [l]abel/ [a]uto [r]epartition/ [b]adblock/ [exe]rcise/ Set the device parameters.
Creating the file systems Create a file system for each new OPEN-x device. To overcome the size and speed limitations of a standard file system (EFS), you may choose to create an extended file system (XFS). The EFS file system creates one file system of 2 GB or less on a single device without the extended logical volume manager (XLV). The XFS file system creates a 64-bit file system capable of scaling to handle extremely large files and file systems. The file system is application dependent.
Creating and verifying the mount directories CAUTION: Do not create mount directories for multiplatform devices. To create and verify the mount directories: 1. Create a mount directory by using the mkdir command. Example For example, to create a mount directory for logical unit 0 on the disk array, partition c, enter: # mkdir HP5700_LU0c 2. Verify the new mount directories by using the ls –d command.
Registering, mounting, and verifying the file systems To register the new file systems in the mount table: 1. Make a backup copy of the mount table; enter: # cp /etc/fstab /etc/fstab.backup 2. Edit the file /etc/fstab by using the vi editor. Example # cp /etc/fstab /etc/fstab.
4. When you are finished adding the new file systems to the mount table, save the changes and exit the vi editor. 5.
4. Verify the file copy operation by listing the files in the current directory: # ls –1 Example # ls -l total 7240 -rwxr-xr-x 1 root sys 3754720 Mar 4 15:08 unix.back1 5. Copy the file again to the mount directory, but in this case change the file name to unix.back2. Example # cp /unix.backup1 /HP5700_LU0/unix.back2 6. List the files again to verify the second file copy operation. Example # ls -l -rwxr-xr-x -rwxr-xr-x 1 1 root root sys sys 3754720 3754720 Mar Mar 4 4 15:08 15:08 7.
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 conditions PCDATA cannot be inserted: Depending on your system configuration, you may be able to view error messages as follows: • In Remote Web Console (Status tab) • In Command View Advanced Edition (“Alerts” panel).
Error Condition Recommended Action Physical volumes cannot be created. Verify that the disk array logical devices are correctly formatted. Logical volumes cannot be created. Verify that the volume capacity for OPEN-x volumes is not greater than the maximum capacity allowed. See the Device Emulations Appendix. Verify that the capacity of the volume group is not less than the total capacity of the partitioned logical volume. A file system is not mounted after rebooting.

Note 1: The availability of a disk type depends on the disk array. Note 2: The devices are defined to the host as SCSI disk devices, even though the interface is Fibre Channel. 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 volume with capacity = 49 MB: # of cylinders = ↑49 × 16/15↑ = ↑52.26↑ (rounded up to next integer) = 53 cylinders OPEN-3/8/9/E: The number of cylinders for a CVS LUSE volume = # of cylinders = ↑ (capacity (MB) specified by user) × 1024/720 ↑ × n Example For a CVS LUSE volume with capacity = 37 MB and n = 4: # of cylinders = ↑37 × 1024/720↑ × 4 = ↑52.
