Tape Drive Logs
The tape drive generates six types of logs (see
“Tape Drive Error Logs”
on
page 146). For troubleshooting errors, you will only use SCSI Check
Condition Error logs, Bugcheck Error logs, and Event Error logs.:
•
“SCSI Check Condition Error Logs”
on page 147
•
“Bugcheck Error Logs (SDLT 600 only)”
on page 150
•
“Event Error Logs (SDLT 600 only)”
on page 152
Log Fields

The logs contain three main fields:
Table 12 Log Field
Descriptions
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 the
drive has had power applied with no
interruptions.
Power cycles (PC) is how many times the
drive has experienced a POC. Each time a
drive logs a Hard Event,
it will increment this
count as well.
