With either a Dell MD3860 or a NetApp external storage array, you may see an error about a drive being bypassed.
BYPASSED_DRIVE-Recovery Failure Type Code: 64
A drive or drive port has been bypassed. This problem can occur for the following reasons:
First attempt to reseat the drive. Remove the drive from the slot for about 30 seconds and then reinsert the drive back into the drawer. Wait for about 1 minute and then recheck the health of the storage array in SANtricity.
If the problem remains, open a case with technical support to get the drive replaced.
