Configuring Disk Array Devices; Device File Name Example - HP StorageWorks XP10000 - Disk Array Configuration Manual

4. Construct the device file name for each device, using the device information, and enter the file
names in your table. Use the following formula to construct the device file name:
cxtydz
where:
x = SCSI bus instance number
y = SCSI target ID
z = LUN
c stands for controller
t stands for target ID
d stands for device
The numbers x, y, and z are hexadecimal.

5. Verify that the SCSI TIDs correspond to the assigned port address for all connected ports (see
mapping tables in
properly.
If the logical devices are not recognized properly:
Check the AL-PA for each port using the LUN Manager software.
If the same port address is set for multiple ports on the same loop (AL with HUB), all port ad-
dresses except one changed to another value, and the relationship between AL-PA and TID
does not correspond to the mapping given in
for each port, reboot the server, and then verify new device recognition again.
If unused device information remains, the TID-to-AL-PA mapping will not correspond to the
mapping given in
new device recognition again.

Configuring disk array devices

Disk arrays are configured using the same procedure for configuring any new disk on the host. This
includes the following procedures:
1. Verifying the device files and drivers
2. Creating the device files
3. Creating the physical volumes
4. Creating new volume groups
5. Creating logical volumes
6. Creating the file systems
7. Setting the I/O timeout parameter
8. Creating the mount directories
