HSG80 Array Controller ACS Version 8.2 User Guide (EK-HSG80-UG. B01, July 1998)

3–34 HSG80 User’s Guide
Note The controller operates with BA370 rack-mountable enclosures
that are assigned ID numbers 0, 2, and 3. These ID numbers are set
through 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.
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 below.
Figure 3–14 PTL Naming Convention
Figure 3–15 shows 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 access to 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, system
administrators of each host must not attempt to access the CCL
simultaneously.
