Failure of Cryptographic Erase task on secured physical disks
Cryptographic Erase is the process of securely erasing all data permanently on an encryption-capable physical disk and resetting
the security attributes. It is used in a couple of scenarios such as deleting a foreign configuration in the event of a forgotten or
lost passphrase or unlocking a disk that had been previously locked.
Cryptographic Erase can be executed only on encryption-capable disks as long as the disks are not hot spares and are not
configured or part of a virtual disk. Ensure that the conditions are met and see Cryptographic Erase.
General issues
PERC card has yellow bang in Windows operating system device
manager
Issue: The device is displayed in Device Manager but has a yellow bang (exclamation mark).
Corrective
Action:
Reinstall the driver. For more information on reinstalling drivers, see Driver support for PERC 11 .
PERC card not seen in operating systems
Issue:
The device does not appear in the Device Manager.
Corrective
Action:
Turn off the system and reseat the controller.
For more information, see Install and remove a PERC 11 card.
Physical disk issues
Physical disk in failed state
Issue:
One of the physical disks in the disk array is in the failed state.
Corrective
Action:
Update the PERC cards to the latest firmware available on https://www.dell.com/support and replace
the drive.
Unable to rebuild a fault tolerant virtual disk
Issue:
Cannot rebuild a fault tolerant virtual disk. For more information, see the alert log for virtual disks.
Probable Cause: The replacement disk is too small or not compatible with the virtual disk.
Corrective
Action:
Replace the failed disk with a compatible good physical disk with equal or greater capacity.
Fatal error or data corruption reported
Issue:
Fatal error(s) or data corruption(s) are reported when accessing virtual disks.
Corrective
Action:
Contact Global Technical Support.
