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.
RAS tickets have three severity levels:
•
Severity 3 — Low severity. 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.
•
Severity 2 — High severity. Indicates that a condition exists within the library that impacts system performance or
redundancy. Typical library operations can continue without immediate corrective action, but a user should investigate
the condition and correct the problem soon.
•
Severity 1 — Urgent. 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 are either not possible or highly unreliable.
When possible, the RAS ticket provides instructions for resolving problems. You can view RAS tickets on both the operator
