Connecting the disk array The HP service representative performs the following steps to connect the disk array to the host: 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. Adding the new device paths to the system After configuring the FCAs and to ensure the new devices are recognized, some FCA drivers require you to configure each LUN individually (either through the driver configuration file or in /kernel/drv/sd.conf). CAUTION: To ensure that the system can boot properly even if you make a mistake in the driver configuration file, add the new paths at the end of the file. (This ensures that the system boot entries higher up in the file will execute first.) Pre-configure additional LUNs (not yet made available) to avoid unnecessary reboots.

After configuring the FCAs and to ensure the new devices are recognized, some FCA drivers
require you to configure each LUN individually (either through the driver configuration file or in

CAUTION:
To ensure that the system can boot properly even if you make a mistake in the driver
configuration file, add the new paths at the end of the file. (This ensures that the system boot entries
higher up in the file will execute first.)
Pre-configure additional LUNs (not yet made available) to avoid unnecessary reboots. See
