COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
If you do not replace the failed drive, the only option using the Array
Configuration Utility is to delete logical drives. Do not delete logical drives that
contain valid data. Doing so results in lost data.
NOTE: A failed status can occur on drives protected by fault tolerance if two
or more physical drives fail concurrently.
Some status indicators are available without pressing F3. For example, on the
Main menu, the FAILED status will appear next to the logical drive that has
failed. EXPANDING and REBUILDING will appear next to the array in which
the activity is occurring.
Handling Disk Drive Failures
If you configured your Smart Array 3200 Controller with hardware fault
tolerance, complete the following steps after a disk drive failure.
1. Determine which physical drive failed. On hot-pluggable drives in a
ProLiant server or storage system, this is indicated by an amber Drive
Failure LED on each drive tray.
2. If the unit containing the failed drive does not support hot-pluggable
drives, perform a normal system shutdown.
3. Remove the failed drive and replace it with a drive of the same capacity.
For hot-pluggable drives, after you secure the drive in the bay, the LEDs
on the drive each light once in an alternating pattern to indicate that the
connection was successful. The Online LED blinks, indicating that the
controller recognized the drive replacement and began the recovery
process.
4. Power-up the server, if applicable.
5. The Smart Array 3200 Controller firmware reconstructs the information
on the new drive, based on information from the remaining physical
drives in the logical drive. While reconstructing the data on hot-
pluggable drives, the Online LED blinks. When drive rebuild is
complete, the Online LED is illuminated.
6. NetWare cannot detect a single physical drive failure when using
hardware-based fault tolerance NetWare considers the data to be is still
valid and accessible during the rebuilding process.
