Running the Array Configuration Utility
■ Rebuilding: The array is operating and rebuilding a replacement drive or
an online spare, if one was assigned.
■ Logical Drive Failed: If you have one or more logical drives that are not
protected by fault tolerance in an array, the data on these logical drives
will be lost. The Array Configuration Utility shows the logical drives as
FAILED. After drive replacement, any fault-tolerant logical drives
rebuild. The logical drives that were not protected (FAILED) become
available for data (the devices are reactivated automatically). If you
have a backup of the data, restore the data now.
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.
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.
If the RA4000 was configured 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 that is 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 on the server, if applicable.
5. The RA4000 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 the drive rebuild is complete, the Online LED is
illuminated.
