DSSI Device
Parameters:
Definitions and
Function
Five principal parameters are associated with each DSSI device:
• Drive ID
• ALLCLASS
• UNITNUM
• NODENAME
• SYSTEMID
Note
ALLCLASS, NODENAME, and UNITNUM are examined
and modified using the
cdp command.
SYSTEMID is examined and modified using the console-
based Diagnostic and Utility Program (DUP) driver
utility.
The drive ID is physically determined by the numbered
drive ID plug that inserts into the front panel of the
storage compartment.
A brief description of each parameter follows.
