About Diagnostic Tickets
The library uses advanced problem detection, reporting, and
notification technology to alert you of problems as soon as they occur.
The library performs numerous self-tests to monitor the library’s
temperature, voltage and currents, and standard library operations. It
performs these self-tests each time the library is powered on and during
normal operation when the library is idle.
If the self-test detects a problem, the library generates a diagnostic
ticket that identifies the component that is likely causing the problem. If
the problem is not severe, the library continues to provide full
functionality to all unaffected partitions.
The tickets are assigned one of three priority levels:
• Urgent — The highest level of priority. A ticket with urgent priority
indicates that a failure has occurred or a serious condition exists
within the library that requires immediate corrective action. In most
cases, a hardware component is no longer functioning at an
acceptable level or has failed. Typical library operations required for
backup or restore operations are either not possible or highly
unreliable. This level of priority is conveying a critical issue.
• High — The middle level of priority. A ticket with high priority
indicates that a condition exists within the library that impacts
system performance, redundancy, or just a specific host application.
Typical library operations can continue without immediate
corrective action, although an application may have failed and may
need to be restarted. A user should investigate the condition and
correct the problem soon. This level of priority is conveying a
warning message.
• Low — The lowest level of priority. A ticket with low priority
indicates that an abnormal condition existed within the library that
warrants investigation and correction but the nature of the
condition may have little or no effect on operations. This level of
priority is conveying an informational message.
