13Troubleshooting
The PowerVault ML6000 library includes advanced system monitoring
and alerting mechanisms that inform you of library status and issues. It
provides you with status information about various library subsystems
and components. It also notifies you of issues it detects and guides you
through diagnosing and correcting issues before problems interfere with
backups.
About RAS Tickets
The PowerVault ML6000 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 Reliability,
Availability, and Serviceability (RAS) ticket that identifies the component
that is likely causing the problem. The library’s light emitting diodes
(LEDs) may also turn on or off and flash to indicate an abnormal state. If
the problem is not severe, the library continues to provide full
functionality to all unaffected partitions.
