Physical Disk Fails During Reconstruction On Redundant Virtual Disk
Issue: A physical disk fails during a reconstruction process on a redundant virtual disk that has a hot
spare.
Corrective
Action:
The dedicated hot spare goes to Ready state and the virtual disk goes to Failed state.
Virtual Disk Fails Rebuild Using A Dedicated Hot Spare
Issue: A virtual disk fails during rebuild while using a dedicated hot spare.
Description: The dedicated hot spare goes to Ready state and the virtual disk goes to 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. For example, there is one
rebuild I/O operation for every five host I/O operations. You cannot add a second virtual disk to
a disk group while the virtual disk in that disk group is undergoing a rebuild. The firmware does
not allow you to create a virtual disk using the free space available in a disk group if a physical
disk in a virtual disk group is undergoing a rebuild operation.
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 dell.com/support/manuals.
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 Using
Replace Member And Revertible Hot Spares.
