Reset Physical Disk
This command power cycles a physical disk in a disk group or a disk pool to aid in the recovery of a
physical disk that is exhibiting inconsistent or non-optimal behavior.
By power cycling a physical disk, some errors that cause inconsistent or non-optimal behavior can be
cleared. This avoids replacing a physical disk when it is experiencing only a transient, non-fatal error, and
the physical disk can remain operational. Resetting a physical disk in this way reduces disruptions and
avoids replacing a physical disk.
If the problem cannot be corrected by power cycling the physical disk, the data is copied from the
physical disk and the physical disk is powered down for replacement.

Parameters
Parameter Description

and the slot ID value of the physical disk that you want to revive. For non-

value of the physical disk that you want to revive. Enclosure ID values are 0
to 99. Drawer ID values are 0 to 4. Slot ID values are 0 to 31. Enclose the
enclosure ID value, the drawer ID value, and the slot ID value in square
