Current Operating Definition
Returns the value of the present operating definition. The default operating definition field returns the value of the operating
definition the disc drive uses when power is applied if no operating definition is saved.
Note. The FC-AL drive always returns a value of 03h in the current and default fields.
00h Use current operating definition.
01h SCSI X3.131-1986 operating definition.
03h SCSI-2 X3.131-199x operating definition.

Peripheral Qualifier and Peripheral Device Type
00h
A direct-access device (magnetic disc) is connected to this logical unit.
SAVIMP (Save Implemented)
For each operating definition there is an associated Save Implemented (SAVIMP) bit. A SAVIMP bit of zero indicates that
the corresponding operating definition parameter cannot be saved. A SAVIMP bit of one indicates that the corresponding
operating definition parameter can be saved. The disc drive saves the default operating definition and all supported operat-
ing definitions.
Supported Operating Definition
