Use the Offline task to deactivate a disk before removing it. Use the Online task to reactivate an offline disk. In some cases, you may want to use the Online
task on a failed disk in an attempt to recover data from the disk. See "Using the Physical Disk Online Command on Select Controllers" for more information.

physical disk causes the Slow Initialize task to be cancelled for the entire virtual disk. See "Format and Initialize; Slow and Fast Initialize" and
"Considerations for Slow Initialize" for more information.
