Configuring the Fibre Channel ports Configure the disk array Fibre Channel ports by using XP Remote Web Console (shown), XP Command View (XP arrays only), or Command View XP Advanced Edition Software. Select the settings for each port based on your storage area - HP XP20000 | HP StorageWorks Disk Array XP operating system configuration guide - Page 16
Set each array port to FABRIC ON or OFF with connections of POINT-TO-POINT or FC-AL as shown in the following figures and table. For detailed topology information, refer to the HP StorageWorks SAN design reference guide at http://www.hp.com. 16 Installing and configuring Linux for the XP disk array - HP XP20000 | HP StorageWorks Disk Array XP operating system configuration guide - Page 17
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. On Linux systems, the disk array only supports QLogic and Emulex adapters.

through a shared port Connecting the disk array The HP service representative connects the disk array to the host by: • Verifying operational status of the disk array channel adapters, LDEVs, and paths. • Connecting the Fibre Channel cables between the disk array and the fabric switch or host - HP XP20000 | HP StorageWorks Disk Array XP operating system configuration guide - Page 19
see HP StorageWorks XP LUN Manager User's Guide or HP StorageWorks Command View XP Advanced Edition Software 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.
