Rebuilding A Failed Physical DiskIssue: Rebuilding a physical disk that is in a failed state.CorrectiveAction:If you have configured hot spares, the PERC card automatically tries to use one ofthe hot spares to rebuild a physical disk that is in a failed state. Manual rebuild isnecessary if no hot spares with enough capacity to rebuild the failed physical disksare available. You must insert a physical disk with enough storage in the subsystembefore rebuilding the physical disk.NOTE: You can use the BIOS Configuration Utility ( ) or Dell OpenManage storagemanagement application to perform a manual rebuild of an individual physical disk. For informationon rebuilding a single physical disk, see Performing A Manual Rebuild Of An Individual Physical Disk.Virtual Disk Fails During Rebuild Using A Global Hot SpareIssue: A virtual disk fails during rebuild while using a global hot spare.Description: The global hot spare reverts to Hotspare state and the virtual disk is in Failed state.Virtual Disk Fails During Rebuild Using A Dedicated Hot SpareIssue: A virtual disk fails during rebuild while using a dedicated hot spare.Description: The dedicated hot spare reverts to Ready state and the virtual disk goes to Failedstate.Physical Disk Fails During Reconstruction On Redundant Virtual DiskIssue: A physical disk fails during a reconstruction process on a redundant virtual disk thathas a hot spare.CorrectiveAction:The dedicated hot spare reverts to Ready state and the virtual disk goes to Failedstate.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 is in Ready state and the virtual disk is in 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 isone rebuild I/O operation for every five host I/O operations. You cannot add asecond virtual disk to a disk group while the virtual disk in that disk group isundergoing a rebuild. The firmware does not allow you to create a virtual disk usingthe free space available in a disk group if a physical disk in a virtual disk group isundergoing a rebuild operation.80
