Start Secure Physical Disk Erase
Description
This command erases all of the data from one or more self-encrypting disk (SED) physical disks so that they can be
reused as SED physical disks. Run this command only when the SED physical disks are no longer part of a secure disk
group, or when the security key is unknown.
NOTE: When performing a secure erase operation on all physical disks in an array that contains only SED physical
disk type, the physical disks must be erased in two groups using the start secureErase
physicalDisks[] command. For example, if there are seven (7) SED physical disks, the secure erase can be
performed by executing:
start secureErase physicalDisks [0,0 0,1 0,2 0,3];
start secureErase physicalDisks [0,4 0,5 0,6];
Syntax
start secureErase (physicalDisk [enclosureID,slotID] |
physicalDisks [enclosureID1,slotID1 enclosureID2, slotID2...
enclosureIDn,slotIDn])
Parameters
Parameter Description
physicalDisk or physicalDisks Identifies the enclosure and slot where the physical disk
resides. Enclosure ID values are 0 to 99. Slot ID values
are 0 to 31. You must put brackets ([ ]) around the
enclosure ID value and slot ID value.
Start Snapshot Rollback
Description
This command starts a rollback operation for one or more snapshot virtual disks. The content of the base virtual disk
changes immediately to match the content of the selected snapshot virtual disk at that point in time. The base virtual
disk immediately becomes available for read/write requests after the rollback operation has successfully completed. To
stop a snapshot rollback operation, use the stop rollback virtual disk command. The repository virtual disk that is
associated with the snapshot continues to track any new changes between the base virtual disk and the snapshot
virtual disk that occurs after the rollback operation is completed.
Syntax
start rollback (virtualDisk [snapshotVirtualDiskName]
|
virtualDisks [snapshotVirtualDiskName1 … snapshotVirtualDiskNameN])
