Dell PowerVault MD3260i - Manual (Page 155)

Parameter Description
members The identifier of one base virtual disk or more than one
base virtual disks that you want to add. The members
identifier is comprised of the base virtual disk name
concatenated with the repository virtual disk name. You
must use a colon (:) between the two names. Enclose all of
the member identifiers in parenthesizes. If you enter more
than one member separated the members with a space.
When you do not use the members parameter, all of the
members are automatically added to the new consistency
group snapshot virtual disk.
repositoryFullLimit The percentage of repository capacity at which the
consistency group snapshot repository virtual disk is
nearing full. Use integer values. For example, a value of
70 means 70 percent.
readOnly The setting to determine whether you can write to the
snapshot virtual disk or only read from the snapshot virtual
disk. To write to the snapshot virtual disk, do not include
this parameter. To prevent writing to the snapshot virtual
disk, include this parameter.
Notes
You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for the names.
Names can have a maximum of 30 characters.
If you do not specify the repositoryVolType or readOnly parameters, the MD storage management software
selects the repositories for the consistency group snapshot virtual disk. If the disk group or disk pool where the base
virtual disk resides does not have enough space, this command fails.
The create cgSnapVirtualDisk command has unique forms that are explained by these examples:
• Creating a read/write consistency group snapshot virtual disk on a snapshot consistency group named snapCG1
that has three members cgm1, cgm2, and cgm3. The repository virtual disks already exist and selected by the
user in this command.
create cgSnapVirtualDisk userLabel="cgSnapVirtualDisk1"
cgSnapImageID="snapCG1:oldest" members=(cgm1:repos_0010 cgm2:repos_0011
cgm3:repos_0007);
Note the use of the colon (:) in the name of the snapshot image to be included in the consistency group snapshot
virtual disk. The colon is a delimiter that separates the name of the snapshot virtual disk from a particular
snapshot image that you might want to use. You can use one of these options following the colon:
– An integer value that is the actual sequence number of the snapshot image.
– newest - Use this option when you want to show the latest consistency group snapshot image.
– oldest - Use this option when you want to show the earliest snapshot image created.
The use of the colon following the names of the members of the snapshot consistency group acts define the
mapping between the member and a repository virtual disk. For example, in cgm1:repos1_10, member cgm1
maps to repository virtual disk repos1_0010.
