Dell 34XX, 38XX, 32XX, 36XX manual Consistency group snapshot repository virtual disk

Parameter	Description
	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.

•Creating a read/write consistency group snapshot virtual disk on a snapshot consistency group named snapCG1 of only members cgm1 and cgm2:

create cgSnapVirtualDisk userLabel="cgSnapVirtualDisk2" cgSnapImageID="snapCG1:14214" members=(cgm1:repos_1000 cgm2:repos_1001);
