FF
Operator
Procedure or Host
Problem
FID FF is always presented to the host in SCSI Request
Sense Data. Some types of problems also present this
FID on the operator panel.
1. FID FF Displayed on Drive Panel: (It also went to
the host.)
v FID FF is automatically displayed when the
operator selects Force Error Dump from the
operator Services menu.
v Action: Remove the dump icon and the FID
message by pressing the Reset Push button or by
powering the drive OFF, and then ON.
v The FID message can be removed without
removing the dump icon by selecting Reset Drive
on the operator Services menu.
2. FID FF Displayed at Host Only - Not on Drive
Panel:
(It went to the host only.)
v The host receives this FID, but it is not presented
on the drive operator panel. If FID FF was
reported in host error log via a SIM message,
then perform action indicated in SIM message
codes (such as clean drive).
v This FID is presented for an invalid and
unsupported SCSI command or parameter, which
is a SCSI application program software problem.
Sense data exists at the host.
v This FID can also be presented for a drive
operator procedural problem. For example, FID
FF is presented when a magazine is not in the
ACF and the host issues a Load command.
Another example is when the operator tries to
switch to random mode and the magazine is not
locked.
