Parameter Description
consistencyGroupName The name of the consistency group for which you
want to start a rollback operation. Enclose the
name of the consistency group in double

When the memberVirtualDiskSet parameter is
not used, the rollback process applies to all
member virtual disks of the consistency group.

disks in a consistency group that you want to
rollback. Enclose each member base virtual disk
name in double quotation marks (" ") inside
parenthesizes (( )).
You can enter more than one member virtual disk
name. Enclose all of the member virtual disk
names in one set of double quotation marks (" ")
inside parenthesizes (( )). Separate each member
virtual disk name with a white space.

To start a roll back operation for base virtual disk members memVol1, memVol2, and memVol3 in a
consistency group that has the name congroup2, you would use this command:
start cgSnapImage ["CG2:12345"] rollback memberVirtualDiskset=("memVol1 memVol2
memVol3");
