Bug Description

Installed icehouse and configured brocade zonemanager to test FC auto zoning for 3par

Setup details
#########
1. Host with multi port HBA
2. Connected to switch with one of the HBA ports in Host (50:01:43:80:21:e3:9b:9c)
3. 2 ports of 3par Storage is connected of switch (20:01:00:02:ac:00:4f:45, 21:01:00:02:ac:00:4f:45)

Problem
######

During the attach of 3par FC volume, zones are getting created automatically by BRCD zone manager but it takes all the available ports in the host, instead of ports only connected to switch because of this zones are created for the unconnected ports on host

This does not appear to be issue with the ZM. Zones are only created for the WWNs that are passed to it in the conn_info.initiator_target_map. If the map contains 2 initiators, then 2 zones will be created.

if N number of ports are available in host, zones will be created for all the available ports thru "conn_info.initiator_target_map"...

Why cant we restrict only which is connected to the switch ?

Can you please post nsshow and nscamshow info from the switch? The zonemanager looks up in the nameserver and only zones those initiators and targets which are found in the name server.

This is working as designed. The FCZM only filters the target WWN list with those available in the name server. All initiators passed in are zoned to allow for pre-provisioning.

This doesn't affect the functioning of the zone manager, nor does it affect the attaching of LUNs to a host. We have plans to use the lookup service, but it also needs to be done correctly so that we can still support multipath and limit the use of the 3PAR NSP ports.
