Compaq HSZ80 manual Unit Numbering Examples, Lun

3–33

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 3–3shows additional unit numbering examples.

Table 3–3 Unit Numbering Examples

Unit Number	Device Type	Target ID Number	LUN
D401	Disk	4	1
D1207	Disk	12	7
D5	Disk	0	5

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.
