NOTE: The Clear Virtual Disk Bad Blocks task is not supported on PERC 12 and later controllers.

The CLI command is used to clear the bad blocks on the affected drives. It only clears the cached errors from the controllers by clearing out the table of bad blocks that the PERC firmware is maintaining for virtual disks. The feature is applicable only to PERC H730P MX and PERC H745P MX.
