Volume access groups
A volume access group is a collection of volumes that users can access using either iSCSI or Fibre Channel initiators.
By creating and using volume access groups, you can control access to a set of volumes. When you associate a set of volumes and a set of initiators with a volume access group, the access group grants those initiators access to that set of volumes.
Volume access groups have the following limits:
A maximum of 128 initiators per volume access group.
A maximum of 64 access groups per volume.
An access group can be made up of a maximum of 2000 volumes.
An IQN or WWPN can belong to only one volume access group.
