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 (" ").
