Users Guide
1 One or more subcomponents are faulty.
2 A non-SAS IOM is detected.
3 An inconsistency is detected in the subcomponent rmware.
Drives on compute sled are not visible
1 If the compute sled is congured with a PERC controller and the drives have been reseated or moved, they are rediscovered as
"Foreign".
2 If the drives are removed from the storage sled, they cannot be discovered.
3 If a storage sled is replaced, the storage conguration of the earlier sled cannot be applied to the replaced sled.
Storage conguration cannot be applied to SAS IOMs
1 If a storage sled is replaced, the storage conguration of the earlier sled cannot be applied to the replaced sled.
2 If a rmware mismatch is detected on the boot of the SAS IOM, the storage conguration is not applied.
3 If a chassis mismatch is detected on the boot of the SAS IOM, the storage conguration is not applied.
4 If the storage sled cannot be communicated with or has an Expander fault, the SAS IOM cannot apply the respective storage
conguration.
Drives in OpenManage are not visible
1 The storage sled may have experienced an Expander failure which blocks the drives from being inventoried.
2 To view the drives, refresh the storage sled inventory.
iDRAC and OpenManage drive information do not match
The drive information of iDRAC and OpenManage may not match owing to the mechanisms that iDRAC and the SAS IOM used to fetch
and detect the storage details for storage sleds.
The assignment mode of storage sled is unknown
1 If the IOM management role is currently downgraded, then the storage sled assignment mode may not be read.
2 You may have to refresh the Storage sled inventory page.
3 If the storage sled health is non-optimal the assignment mode may be downgraded.
