Adding The New Device Paths To The System; Verifying Host Recognition Of Disk Array Devices; Configuring Disk Array Devices - HP StorageWorks P9000 Configuration Manual

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:
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
and configuring the FCAs" (page 79)

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 Oracle 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 Oracle SAN driver and P9000 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" (page 85)
2. "Creating the file systems" (page 85)
3. "Creating the mount directories" (page 86)
84 Solaris
To ensure that the system can boot properly even if you make a mistake in the driver
for individual driver requirements.
