Dell PowerVault MD3420 - Manual (Page 375)

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])
Parameters
Parameter Description
virtualDisk or
virtualDisks
Names the specific snapshot virtual disk or
snapshot virtual disks for which you want to start a
rollback operation. Enclose the snapshot virtual
disk name in square brackets ([ ]). If the snapshot
virtual disk name has special characters, you must
also enclose the snapshot virtual disk name in
double quotation marks (" ").
