The service representative makes note of the part identifier (FID) 1 and
the severity code 2. The service representative then uses the FID number
3 to enter the Maintenance Package. The message area of 4,5, and
6 hex data is support information to help determine if model-unique
Licensed Internal Code causes the fault.
vAttention Messages
Attention (ATTN) messages indicate errorconditions that customer
personnel may be able to resolve. For example, the operator can correct the
ATTNACF message with a supplemental message of Magazine not locked.
vRoutine Messages
Routine Messages consist of messages that are received from the host
through the SCSI Display Message command (for example, Mount), and
messages from the device (for example, *CLEAN).
Togenerate the Clean message, the device monitors the number of
megabytes that are processed and the number of nonpermanent errors for
each drive. When either of these factors reaches a threshold, the device
displays a Clean message. The clean message is maintained across device
power-on reset conditions.
The routine messages that are received through the Display Message
command consist of mount messages, demount messages, and general
(custom) messages.
The routine messages usually refer to the priority cell. Actions that are
automatically handled by the ACF usually occur without the display of an
operator message. The initiator can generate these messages. If, however,
the device microcode detects that the ACF will automatically perform the
action requested, any corresponding message is suppressed.
vFID2 Messages
A FID2 message indicates that the drive is in a degraded state. For example,
FID2 E4 could indicate that one SCSI port has a fault. The drive is usable,
but is in a less available state.
vFID3 Messages
A FID3 message indicates that the drive is in a degraded state. The drive is
usable, but is in a more available state than for a FID2 type of fault.
