Compaq HSZ80 Array Controller ACS Version 8.3 Configuration and CLI Reference Guide
Omit the leading zeroes for storage units associated with the controller’s SCSI
target ID zero. For example, use D2 instead of D002 for a storageset that’s
accessed through LUN 2 of the controller’s SCSI target ID 0. Table 3–3 shows
additional unit numbering examples.
NOTE: The host communicates with a logical unit based on its LUN address. The
controller communicates with a device based on its Port-Target-LUN (PTL) address
CAUTION: Selecting SCSI-3 mode enables access to the Command
Console LUN (CCL) by all hosts. If the hosts access the CCL simulta-
neously, unpredictable consequences can occur. In cases where the CCL
can be accessed through multiple paths and LUNs, systems administra-
tors of each host must not attempt to access the CCL simultaneously.
