Storage Group Operations

The Storage Group Operations described below help administrators assign LUNs to specific hosts (or servers). By default, when a volume is created it is not visible to any host. It is necessary to specifically define which hosts can access the new volume.

Storage Groups are logical entities in the EMC SMI-S Provider that describe which hosts can access which volumes through which controller port. A Storage Group contains hosts and LUNs. Hosts in a Storage Group can access all LUNs that are members of the same group.

The following Storage Group-related operations are supported:

•	create-storage-group, to create a new Storage Group

•	get-storage-group, to list the defined Storage Group and see which hosts can access which LUNs

•	delete-storage-group, to delete an existing Storage Group

•	add-host-to-storage-group, to link a host to an existing Storage Group

•	add-lun-to-storage-group, to link a LUN to an existing Storage Group

•	add-port-to-storage-group, to create an additional path visible to the set of hosts

•	remove-host-from-storage-group, to remove a host from an existing Storage Group

•	remove-lun-from-storage-group, to remove a LUN from an existing Storage Group

•	get-host, to list all the host and their characteristics in a specific Storage Group

•	get-port, to list of the controller ports of a Storage Group
