• read-only• repository full value• automatic repository selectionUnique command syntax and naming rules apply. The name of a snapshot image has two parts separatedby a colon (:):• identifier of the snapshot group• identifier of the snapshot imageIf you do not specify the repositoryVirtualDiskType or readOnly parameters, the repositories forthe consistency group snapshot virtual disk will be selected automatically. If the disk group or disk poolwhere the base virtual disk resides does not have enough space, the command will fail.Create a read/write consistency group snapshot virtual disk on a snapshot consistency group namedsnapCG1 with these three members cgm1, cgm2, and cgm3. The repository virtual disks already exist andare selected in this command.create cgSnapVirtualDisk userLabel="cgSnapVirtualDisk1"cgSnapImageID="snapCG1:oldest" members=(cgm1:repos_0010 cgm2:repos_0011cgm3:repos_0007);Note the colon (:) in the name of the snapshot image to be included in the consistency group snapshotvirtual disk. The colon is a delimiter that separates the name of the snapshot virtual disk from a particularsnapshot image that you might want to use. Any of the following three options can be used following thecolon:• An integer value that is the actual sequence number of the snapshot image.• NEWEST specifies the latest consistency group snapshot image.• OLDEST specifies the earliest snapshot image created.The use of the colon following the names of the members of the snapshot consistency group define themapping between the member and a repository virtual disk. For example:cgm1:repos_10, member cgm1 maps to repository virtual disk repos_0010Create a read-only consistency group snapshot virtual disk on a snapshot consistency group namedsnapCG1 with members cgm1, cgm2, and cgm3 using the following command:create cgSnapVirtualDisk userLabel="cgSnapVirtualDisk3"cgSnapImageID="snapCG1:oldest" readOnly;Create a consistency group snapshot virtual disk that has a repository full limit set to 60 percent on asnapshot consistency group named snapCG1 with these three members cgm1, cgm2, and cgm3, withthe following command:create cgSnapVirtualDisk userLabel="cgSnapVirtualDisk3"cgSnapImageID="snapCG1:oldest" repositoryFullLimit=60;Create a read/write consistency group snapshot virtual disk with automatic repository selection on asnapshot consistency group named snapCG1 with members cgm1, cgm2, and cgm3, with the followingcommand:create cgSnapVirtualDisk userLabel="cgSnapVirtualDisk4"cgSnapImageID="snapCG1:oldest";Creating A Consistency Group Snapshot ImageTo create a new snapshot image for each base virtual disk in snapshot consistency group, use thecreate cgSnapImage command.
