Dell PowerVault MD3420 - Manual (Page 387)

Notes
Names can be any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#).
Names can have a maximum of 30 characters.
One technique for naming the snapshot (legacy) virtual disk and the snapshot (legacy) repository virtual
disk is to add a hyphenated suffix to the original base virtual disk name. The suffix distinguishes between
the snapshot (legacy) virtual disk and the snapshot (legacy) repository virtual disk. For example, if you
have a base virtual disk with a name of Engineering Data, the snapshot (legacy) virtual disk can have a
name of Engineering Data-S1, and the snapshot (legacy) repository virtual disk can have a name of
EngineeringData- R1.
If you do not choose a name for either the snapshot (legacy) virtual disk or the snapshot (legacy)
repository virtual disk, the MD storage management software creates a default name by using the base
virtual disk name. An example of the snapshot (legacy) virtual disk name that the RAID controller modules
might create is, if the base virtual disk name is aaa and does not have a snapshot (legacy) virtual disk, the
default snapshot (legacy) virtual disk name is aaa-1. If the base virtual disk already has n-1 number of
snapshot (legacy) virtual disks, the default name is aaa-n. An example of the snapshot (legacy) repository
virtual disk name that the RAID controller module might create is, if the base virtual disk name is aaa and
does not have a snapshot (legacy) repository virtual disk, the default snapshot (legacy) repository virtual
disk name is aaa- R1. If the base virtual disk already has n-1 number of snapshot (legacy) repository virtual
disks, the default name is aaa-Rn.
Stop Snapshot (Legacy) Rollback
Description
NOTE: With firmware version 7.83, the orderterms in the syntax is changed to be consistent with
other commands. Replace the deprecated command syntax with the new command syntax.
This command stops a snapshot rollback operation that was initiated by the start rollback virtual
disk command.
NOTE: Canceling a rollback operation leaves the base virtual disk in an indeterminate state with
potentially invalid or inconsistent data. The related snapshot virtual disk becomes disabled and
unusable.
Syntax
Deprecated
stop rollback (virtualDisk [snapshotVirtualDiskName |
virtualDisks [snapshotVirtualDiskName1 ... snapshotVirtualDiskNameN])
New
stop (virtualDisk [snapshotVirtualDiskName ] |
virtualDisks [snapshotVirtualDiskName1 ... snapshotVirtualDiskNameN]) rollback
Parameters
Parameter Description
virtualDisk The name of the snapshot (legacy) virtual disk for
which you want to stop a rollback operation.
