Verifying Host Recognition Of Disk Array Devices; Configuring Disk Array Devices - HP XP20000/XP24000 Configuration Manual

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. Refer to

Verifying host recognition of disk array devices

Verify that the host recognizes the disk array devices as follows:
1. Use format to display the device information.
2. Check the list of disks to verify the host recognizes all disk array devices. If any devices are
missing or if no array devices are shown, check the following:
SAN (zoning configuration and cables)
Disk array path configuration (FCA HBA WWNs, host group 09 and host group mode 7 set,
and LUNs defined for the correct array ports)
Verify that host group 09 and host group mode 7 are set. Although host group mode 7 is
required only with the Sun SAN driver stack, always setting it is a best practice.
Host FCA configuration (WWN information, driver instance, target and LUN assignment,
and /var/adm/messages)
If you are using the Sun SAN driver and XP LUNs were not present when the configuration
was done, you may need to reset each FCA if no LUNs are visible. The following example
shows the commands to detect the FC-fabric attached FCAs (c3, c5) and resetting them.
# cfgadm -l | grep fc-fabric
c3
c5
# luxadm -e forcelip /dev/cfg/c3
# luxadm -e forcelip /dev/cfg/c5

Configuring disk array devices

Disk arrays are configured using the same procedure for configuring any new disk on the host. This
typically includes the following procedures:
1. Labeling and partitioning the devices
2. Creating the file systems
3. Creating the mount directories
TIP:
Creating scripts to configure all devices at once may save you considerable time.
