vxassist snapclear
vxassist -g<DynamicDiskGroupName> snapclear
<VolumeName |SnapVolumeName | DriveLetter | VmName |DrivePath> [plex=<SnapPlexName>] [<SnapshotName>]
Clears the association between the original volume and the snapshot volume and makes the snapshot volume and original volume two independent volumes. The vxassist snapclear command can be specified only after the vxassist snapshot command has been issued. After the vxassist snapclear command runs, the snapshot volume becomes an ordinary volume and cannot be snapped back to the original volume.
With SFW, it is possible to do a snapclear operation on the original volume. You might want to clear the original volume in two situations: 1) A snapshot volume is deported to a second host and then deleted on that host, and 2) A snapclear is done on the snap volume but the original volume is offline and later this volume comes online.
Note:
Dynamic disks belonging to a Microsoft Disk Management Disk Group do not support the vxassist snapclear command.
The following attributes apply:
-g<DynamicDiskGroupName> | Needed if you use the internal volume name or original volume name. |
<VolumeName> | The name of the original volume. |
<SnapVolumeName> | The name of the volume that is associated with the snapshot plex, the volume that is broken off through the vxassist snapshot command. |
<DriveLetter> | The drive letter of the snapshot volume. |
<VmName> | Internal name of the volume; requires the use of the -g option, such as -gDG1 Volume1. |
<DrivePath> | A volume that is mounted on an NTFS folder; it is indicated by a path to that folder. |
plex=<SnapPlexName> | Name or GUID of the mirror plex. |
<SnapshotName> | Optional name that is assigned to the snapshot volume. |
Examples
vxassist snapclear H:
This command clears the association between the snapshot volume H and the original volume.
vxassist snapclear e: plex=volume1-01
This clears the association of e: (the snapshot volume) with its master volume.
vxassist snapclear F: snapvolume01
This command clears the association of master volume (F:) with its snapshot volume named "snapvolume01."
Note:
When you use the snapback command to clear the association of the master volume, you must use the <SnapPlexName> or the <Snapshot name> when referring to the snapshot volume.
