Troubleshooting
The
Scalar i50
0 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
Scalar i500
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.
