Alert:
Unable to initialize Enclosure Disk "disk number" with Serial Number "number" from controller "number"
Cause
Reason:
A controller has lost the ability to communicate with a disk even though lower layers (JBOD, SAS) remain up and operational.
Resolution
It may be possible that this is a benign alert if the controller is trying to initialize a disk that has recently been deleted.
In a more serious case, the controller has lost the ability to communicate with a disk that contains data.
In some scenarios, the resolution is to reboot the controller. This should be done in consultation with Dell Technical Support.
