After a masking view exists, any changes to its grouping of initiators, ports, or storage
devices automatically propagate throughout the view, automatically updating the
mapping and masking as required.
Auto-provisioning group components
The components of an auto-provisioning group are as follows:
Initiator group
A logical grouping of Fibre Channel initiators. An initiator group is limited to either
a parent, which can contain other groups, or a child, which contains one initiator
role. Mixing of initiators and child name in a group is not supported.
Port group
A logical grouping of Fibre Channel front-end director ports.
The maximum ports in a port group is 32.
Storage group
A logical grouping of thin devices. LUN addresses are assigned to the devices
within the storage group when the view is created if the group is either cascaded
or stand alone.
Cascaded storage group
A parent storage group comprised of multiple storage groups (parent storage
group members) that contain child storage groups comprised of devices. By
assigning child storage groups to the parent storage group members and applying
the masking view to the parent storage group, the masking view inherits all
devices in the corresponding child storage groups.
Masking view
An association between one initiator group, one port group, and one storage
group. When a masking view is created, the group within the view is a parent, the
contents of the children are used. For example, the initiators from the children
initiator groups and the devices from the children storage groups. Depending on
the server and application requirements, each server or group of servers may
have one or more masking views that associate a set of thin devices to an
application, server, or cluster of servers.
