Persistent volumes that are associated with management services are created and assigned

to a new account during installation or upgrade. If you are using persistent volumes, do not
modify or delete the volumes or their associated account

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 64 IQNs or WWPNs are allowed in an access group.
• An access group can be made up of a maximum of 2000 volumes.
• An IQN or WWPN can belong to only one access group.
• A single volume can belong to a maximum of four access groups.

Initiators
Initiators enable external clients access to volumes in a cluster, serving as the entry point
for communication between clients and volumes. You can use initiators for CHAP-based
rather than account-based access to storage volumes. A single initiator, when added to a
volume access group, allows volume access group members to access all storage
volumes added to the group without requiring authentication. An initiator can belong to
only one access group.
