IBM Tape Library: Library Status
This check displays the device status per library, as well as the
drive count and any faults the device reports itself.
The check status will be the worst status derived from device status
and severity of the current fault (if any).
Device Status will resolve to
OK if the device status is documented
WARN if it's "non-critical", "other" or "unknown" and
CRIT for "critical" and "non-Recoverable" status.
No fault or "informational" faults lead to status
OK, "minor" faults
WARN, "major" and "critical" faults to
ID of the library
One service is created for each connected library.
