Update logs
Update Logs record firmware changes and upgrades in the autoloader. An
Update Log
also records when hardware is updated or changed.
Boot logs
Boot logs keep track of the boot status in terms of number of hours the
autoloader has been powered on, the number of times the autoloader has been
rebooted, and the reason for the reboot.
Tape drive logs
Tape drive error logs
The tape drive generates six types of logs. For troubleshooting errors, you
should only use the SCSI Check Condition Error log.
Partial information about tape drive error logs can be retrieved from SCSI. All
tape drive error logs contain three main fields: Event Log Number, Event
Number or Name, and POH/PC.
In addition to these main fields, each type of log contains specialized fields.
SCSI check condition error logs
SCSI Check Condition Error logs record SCSI events that are sent to the host
when a command fails. These logs may be related to the events logged
previously, indicating that the event created a check condition that the host
should know about.
Field
Description
Event Log Number
A sequence number that indicates the order in which the event was logged.
Event Number or Name
This field appears in every event log, but varies depending on the event type. This
field indicates the type of log.
POH/PC
The tracking information for how many power-on-hours (POH) the drive has had
since it was shipped. This is how many hours the drive has had power applied
regardless of the number of times it is turned on and off. POH is updated once every
60 minutes that the drive has had power applied to it without interruptions.
Power cycles (PC) is how many times the drive has experienced a power-on cycle.
Each time a drive logs a Hard Event, it increments this count as well.
Field
Description
Media ID (MID)
A Media ID which is an internal identification number, written to the media the first
time the media is used, to aid in tracking the media to the different events. This
ID does not correlate to any media ID used by application software.
