Figure 20: Mapping a unit to physical disk drives
The HSG80 controller identifies devices based on a Port-Target-LUN (PTL)
numbering scheme, shown in Figure 21. The physical location of a device in its
enclosure determines its PTL.
■ P—Designates the controller's SCSI device port number (1 through 6).
■ T—Designates the target ID number of the device. Valid target ID numbers
for a single-controller configuration and dual-redundant controller
configuration are 0–3 and 8–15, respectively. (This applies to the BA370
cabinet only.)
■ L—Designates the logical unit (LUN) of the device. For disk devices the LUN
is always 0.
