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 | 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 | Perform the following steps: | |
Action: | 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.
