Troubleshooting Tools

The Modular Disk 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:
connecting the host port of one controller to the unused expansion port on the
other controller in a MD3000i enclosure.
• 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.
