Unit Numbering Examples - Compaq StorageWorks HSZ80 Configuration And Cli Reference Manual

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.
Table 3–3 Unit Numbering Examples
Unit Number
D401 Disk
D1207 Disk
D5 Disk
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.
