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 “SCSI TID map for Fibre Channel adapters (HP-UX)” (page 113), for values).
If so, the logical devices are recognized 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
addresses except one changed to another value, and the relationship between AL-PA and
TID does not correspond to the mapping given in “SCSI TID map for Fibre Channel
adapters (HP-UX)” (page 113), set a different address 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 “SCSI TID map for Fibre Channel adapters (HP-UX)” (page 113).
Renew the device information, and then verify 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” (page 19)
2. “Creating the physical volumes” (page 19)
3. “Creating new volume groups” (page 19)
4. “Creating logical volumes” (page 20)
5. “Creating the file systems” (page 22)
6. “Setting the I/O timeout parameter” (page 22)
7. “Creating the mount directories” (page 23)
8. “Mounting and verifying the file systems” (page 24)
9. “Setting and verifying the auto-mount parameters” (page 24)
The HP-UX system uses the Logical Volume Manager (LVM) to manage the OPEN-x devices on the
disk array. The instructions in this section do not explicitly cover all LVM configuration issues. For
further information on LVM configuration, see the HP-UX user documentation.
HP System Administrator Manager (SAM) can be used instead of UNIX commands to configure
SCSI disk devices. See “Reference information for the HP System Administrator Manager
