If instructed to do so, you can manually fail a drive.
About this task
System Manager monitors the drives in the storage array. When it detects that a drive is generating a lot of errors, the Recovery Guru notifies you of an impending drive failure. If this happens and you have a replacement drive available, you might want to fail the drive to take preemptive action. If you do not have a replacement drive available, you can wait for the drive to fail on its own.
