Physical Disk Fails During Reconstruction On Redundant Virtual DiskIssue: A physical disk fails during a reconstruction process on a redundant virtual disk that has a hotspare.CorrectiveAction:The dedicated hot spare goes to Ready state and the virtual disk goes to Failed state.Virtual Disk Fails Rebuild Using A Dedicated Hot SpareIssue: 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 RebuildIssue: 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 onerebuild I/O operation for every five host I/O operations. You cannot add a second virtual disk toa disk group while the virtual disk in that disk group is undergoing a rebuild. The firmware doesnot allow you to create a virtual disk using the free space available in a disk group if a physicaldisk in a virtual disk group is undergoing a rebuild operation.SMART ErrorsSMART monitors the internal performance of all motors, heads, and physical disk electronics and detects predictablephysical disk failures.NOTE: For information about where to find reports of SMART errors that could indicate hardware failure, see theDell OpenManage storage management documentation at dell.com/support/manuals.Smart Error Detected On A Physical Disk In A Redundant Virtual DiskIssue: A SMART error is detected on a physical disk in a redundant virtual disk.CorrectiveAction: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 isforced 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 sourcephysical disk of a virtual disk to a target physical disk that is not a part of the virtualdisk.
