Troubleshooting Tools
The MD Storage Manager establishes communication with each managed
array and determines the current array status. When a problem occurs on a
storage array, MD Storage Manager provides several ways to troubleshoot the
problem:
• Recovery Guru — The Recovery Guru diagnoses critical events on the
storage array and recommends step-by-step recovery procedures for
problem resolution. To access the Recovery Guru using MD Storage
Manager, click Support
→ Recover from Failure. The Recovery Guru can
also be accessed from the Status area of the Summary page.
NOTE:
A SAS Device Miswire Recovery Guru condition can be generated by
connecting the host port of one controller to the unused expansion port on the
other controller in a MD3000 enclosure. After fixing the miswire condition,
power cycle the MD3000 to clear the Recovery Guru condition.
• Storage Array Profile — The Storage Array Profile provides an overview of
your storage array configuration, including firmware versions and the
current status of all devices on the storage array. To access the Storage
Array Profile, click Support
→ View storage array profile. The profile can
also be viewed by clicking the Storage array profile link in the Hardware
Components area of the Summary tab.
• Status Icons — Status icons identify the six possible health status
conditions of the storage array. For every non-Optimal status icon, use the
Recovery Guru to detect and troubleshoot the problem.
– Optimal — Every component in the managed array is in the desired
working condition.
– Needs Attention — A problem exists with the managed array that
requires intervention to correct it.
– Fixing — A Needs Attention condition has been corrected and the
managed array is currently changing to an Optimal status.
