Compaq HSZ80 manual PTL Naming Convention

3–37

NOTE: The controller operates with BA370 rack-mountable enclosures assigned enclosure ID numbers 0, 2, and 3. You set these ID numbers using the PVA module. Enclosure ID number 1, which houses devices at targets 4 through 7, is not supported. Do not use device target ID numbers 4 through 7 in a storage subsystem.

■L—Designates the LUN of the device.

Place one space between the port number, target number, and the two-digit LUN number when entering the PTL address. An example of a PTL address is shown in Figure 3–11.

1 02 00

LUN 00 (leading zeros are not required)

Target 02 (leading zeros are not required)

Port 1

Figure 3–11. PTL Naming Convention

Figure 3–12shows the addresses for each device in an extended configuration. Use this figure along with “Configuration Rules,” page 2–2,to help you work with the devices in your configuration.

CAUTION: Selecting SCSI-3 mode enables LUN 0 of each target for the Command Console LUN (CCL) by all hosts. If the hosts access the CCL simultaneously, unpredictable consequences can occur. In cases where the CCL can be accessed through multiple paths and LUNs, systems administrators of each host must not attempt to access the CCL simulta- neously.
