Redundant virtual disk fails during reconstruction
Issue: Multiple disks fails during a reconstruction process on a redundant virtual disk that has a hot spare.
Probable Cause: Multiple physical disks in the virtual disk is failed or the cables are disconnected.
Corrective
Action:
No action is required. The physical disk to which a reconstruction operation is targeted reverts to Ready
state, and the virtual disk goes to Failed state. If there are any other virtual disks that can be supported
by the capacity of the hot spare then the dedicated hot spare is converted to global hot spare, if not the
hot spare will revert back to Ready state.
Virtual disk fails rebuild using a dedicated hot spare
Issue: A virtual disk fails during rebuild while using a dedicated hot spare.
Probable Cause: One or more disks in the virtual disks fails or is disconnected while the rebuild is in progress.
Corrective
Action:
No action is required. The dedicated hot spare is in hot spare state and converted to global hot spare if
there is any other virtual disk that is supported, otherwise the dedicated hot spare reverts to Ready state
and the virtual drive is in Failed state.
Physical disk takes a long time to rebuild
Issue: A physical disk is taking longer than expected to rebuild.
Description: A physical disk takes longer to rebuild when under high stress. There is only one rebuild I/O operation for
every five host I/O operations.
Corrective
Action:
If possible, reduce stress on the physical disk.
SMART errors
SMART monitors the internal performance of all motors, heads, and physical disk electronics and detects predictable physical
disk failures.
NOTE:
For information about where to find reports of SMART errors that could indicate hardware failure, see the Dell
OpenManage storage management documentation at www.dell.com/openmanagemanuals.
Smart error detected on a physical disk in a redundant virtual disk
Issue:
A SMART error is detected on a physical disk in a redundant virtual disk.
Corrective
Action:
Perform the following steps:
1. Back up your data.
2. Force the physical disk offline.
NOTE: If a hot spare is present, the rebuild starts with the hot spare after the disk is forced
offline.
3. Replace the disk with a new physical disk of equal or higher capacity.
4. Perform the Replace Member operation.
NOTE: The Replace Member operation allows you to copy data from a source physical disk of
a virtual disk to a target physical disk that is not a part of the virtual disk. For more information
about the Replace Member feature, see the topic Configuring hot spare.
