Description Andy Grover 2012-11-21 20:02:06 UTC

+++ This bug was initially created as a clone of Bug #878711 +++

Description of problem:

Can we support to create the wwn alias which is the general function of the storage array.

It will benefit the users that they don't have to always remember which wwn is belong which initiator. 

The following is the layout of netapp wwn alias ( they call it igoup ).
It can assign multiple WWNs to one igroup.

Comment 1 Andy Grover 2012-11-21 20:04:04 UTC

Initiators should be groupable by iqn (for iscsi) or wwn (for fc/fcoe) so they can have ACLs managed for all of them in the group at once.

Comment 2 Xiaowei Li 2012-11-23 05:59:24 UTC

Another request is to set the auto_add_mapped_luns to false.

Usually the users need to do lun mapping manually.

set the default auto_add_mapped_luns to false.

Comment 5 Andy Grover 2013-07-03 18:31:02 UTC

implemented using tag and untag commands under 'acls' node.
