Troubleshooting
D-12 HP StorageWorks Modular Smart Array 500 System User Guide
If a drive fails and you have hardware fault tolerance enabled, system operations
continue. However, you should replace the drive as soon as possible to prevent
failure of the array. If you do not replace the failed drive, the only option using
CPQONLIN is to delete logical volumes. Do not delete logical volumes that contain
valid data, or the data will be lost.
To monitor the status of a drive recovery, select the logical drive on the Main
Configuration screen and press F3. The Logical Drive Information screen shows
the status of the drive.
• Interim Recovery: The logical drive is operating, but a failed drive has not been
replaced. Replace the drive as soon as possible.
• Ready for Recovery: The logical drives are queued for recovery. This status is
displayed when another logical drive is already rebuilding or expanding.
• 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, the data on these logical drives is lost; CPQONLIN
shows these logical drives as failed. After hard drive replacement, any
fault-tolerant logical drives will rebuild. The logical drives that were not
protected (failed) will become available for data (the devices are reactivated
automatically). If you have a backup of the data, restore the data now.
The following pages describe recovery procedures for systems that are using
hardware-based fault tolerance, software-based (NetWare) fault tolerance, and no
fault tolerance.
