1 Installation Installation of the HP StorageWorks Disk Array XP is performed by your HP service representative and you. The HP service representative installs the disk array and formats the disk devices. You configure the host server for the new devices with assistance from the HP service representative.
Features and requirements The disk array and host have the following features and requirements. • HP StorageWorks disk arrays: XP48: Up to 48 drives from 72 GB to 8.7 TB, 24 FC ports XP128: From 8 to 128 drives for up to 18 TB, 48 FC ports XP512: Up to 512 drives from 72 GB to 93 TB, 48 FC ports XP1024: From 8 to 1024 drives for up to 149 TB, 64 FC ports • IBM NUMA-Q series enterprise system • DYNIX/ptx operating system • Host Bus Adapters (HBAs): Install adapters and all utilities and drivers.
Fibre Channel interface The XP48, XP128, XP512, and XP1024 disk arrays support these 1 Gbps and 2 Gbps Fibre Channel interfaces: • 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 fabric direct attach • Fibre Channel switches 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.
Failover The disk arrays support many standard software products that provide host, application, or I/O path failover and logical volume (storage) management. SNMP configuration The disk arrays support standard Simple Network Management Protocol (SNMP) for remotely managing the disk array from the host. The SNMP agent on the remote console PC or Command View can provide status and Remote Service Information Message (R-SIM) reporting to the SNMP manager on the host for up to eight disk arrays.
Installation procedures The HP representative and you perform the following procedures: 1. “Install and configure the disk array” on page 14 • 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” on page 18 • 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 the following tasks: • Assembling hardware and installing software • Loading the microcode updates • Installing the channel adapters (CHAs) and cabling • Installing and formatting devices You perform the additional tasks below. If you do not have Command View or LUN Configuration Manager, your HP service representative can perform these tasks for you.
Configuring the Fibre Channel ports Configure the disk array Fibre Channel ports by using Command View (shown) or the Fibre Parameter window in LUN Configuration Manager. 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 You can 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 hp.com website.
Setting the Host Mode for the disk array ports The disk array ports have Host Modes that you must set depending on the host you use. After the disk array is installed, use Command View (shown) or LUN Configuration Manager to set the Host Mode for each port. The host mode setting for DYNIX/ptx is 04.
Install and configure the host 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 By using appropriate zoning and LUN security, you can connect multiple clusters of various operating systems to the same switch and fabric: • Host zones must contain only homogeneous operating systems. • Storage port zones may overlap if more than one operating system needs to share an array port.
Connect the disk array Connect the disk array to the host as follows: 1. The HP service representative verifies operational status of the disk array channel adapters, LDEVs, and paths. 2. The HP representative connects the Fibre Channel cables between the disk array and the fabric or host. 3. Verify the ready status of the disk array and peripherals.
Defining the paths Use Command View (shown) or LUN Configuration Manager to create paths (LUNs) between hosts and volumes in the disk array, also called LUN mapping. LUN mapping includes these tasks: • Configuring ports • Setting LUN security • Creating host groups by operating system and setting their host modes • Assigning host bus adapter WWNs to host groups. • Mapping volumes to host groups (by assigning LUNs). For details, see the Command View or LUN Configuration Manager guide.
Verifying disk array device recognition Verify that the host recognizes the disk array devices: 1. Log into the host as an administrator (root). 2. Check the list of peripherals on the host to verify the host recognizes all disk array devices. If any devices are missing, check disk array path configuration, check host HBA configuration, and check cables. 3. Record the disk numbers and other device information on the worksheet in Appendix A.
Configure disk array devices Configure the disk array devices in the same way you would configure any new disk on the host. Creating scripts to configure all devices at once may save you considerable time. 1. Configuring devices typically requires these steps: Initialize, partition, and label each device using the disk management utility provided with the host. 2. Create a file system for each device. 3. Create a mount directory for each device. 4. Enter each device into the mount table. 5. Reboot the host.
2 Troubleshooting If you encounter an error condition, see “Error conditions” on page 26 for recommended actions. If you are unable to resolve an error condition, ask your HP support representative for assistance. See “Calling the HP support center” on page 28.
Error conditions Error Condition Recommended Action The logical devices are not recognized by the host. Verify that the READY indicator lights on the disk array are ON. Verify that fiber cables are correctly installed and firmly connected. Verify that the target IDs are properly configured. The LUNs for each TID must start at 0 and continue sequentially without skipping any numbers. Verify that the TIDs/WWNs on each bus are unique. Do not install two devices with the same ID on the same bus.
Error Condition Recommended Action A file system is not mounted Verify that the host was restarted correctly. after rebooting. Verify that the file system attributes are correct. The disk array performs a Reboot the host. self reboot because the disk array was busy or it logged a panic message. The disk array responds “Not Contact HP. Ready” or the disk array has displayed “Not Ready” and timed out. The host detects a parity error. Check the HBA and make sure it was installed properly. Reboot the host.
Calling the HP support center If you need to call HP customer support, provide as much information about the problem as possible, including the circumstances of the error or failure and the exact content of any error messages. Depending on your system configuration, you may be able to view error messages as follows: • View SIMs in Command View (Device Health tab). • View R-SIMs in Remote Control XP, including reference codes and severity levels of recent R-SIMs.

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 a CVS LUSE volume with capacity = 37 MB and n = 4 # of cylinders = ↑ 37 × 1024/720↑ × 4 = ↑ 52.62↑ × 4 = 53 × 4 = 212 OPEN-V: The number of cylinders for a CVS LUSE volume = # of cylinders = ↑ (capacity (MB) specified by user) × 16/15 ↑ × n Example: For an OPEN-V CVS LUSE volume with capacity = 49 MB and n=4 # of cylinders = ↑ 49 × 16/15↑ × 4 = ↑ 52.
