Hi,While creating Zone , Do we need to create two zones for Two HBA for a host connected with SAN ? Or a zone is enough for
a host which having Two HBAs...We have two 9124s for our SAN fabric...
As I found like one zone below, I little bit confused that , if a host having two HBA connected with SAN, should I expect two zones for every Host?
from the zone set, I gave the command show zoneset
zone name SQLSVR-X-NNN_CX4 vsan 1
pwwn 50:06:NN:NN:NN:NN:NN:NN
pwwn 50:06:NN:NN:NN:NN:NN:NN
pwwn 10:00:NN:NN:NN:NN:NN:NN
But I found only one zone for the server's HBA2:by the same time in the fabric I found switches A & B showing the WWNs of those HBAs on its
connected N port...Its not only for this server alone, but for all hosts..Can you help me to clarify on this please..that should we need to create one zone for
one HBA?

Hi Kumara,
Are the 9124's used to provide two indepenent paths/fabrics between your hosts and storage?

if u have two independent fabrics between hosts and storage, i think the below confs are recommended.
Scenario 1: 2 HBAs single port each ( redundancy across HBA / Storage port )
HBA1 - port 0 ---------> Fabric A ----------> Storage port ( FAx/CLx )
HBA2 - port 0 ---------> Fabirc B ----------> Storage port ( FAy/CLy )
Scenario 2: 2 HBAs of dual port each
HBA1 - port 0 -------> Fabric A ---------> Storage port ( FAx/CLx )
HBA2 - port0 ---------> Fabric A ---------> Storage port ( FAs/CLs )
HBA1 - port 1 --------> Fabric A --------> Storage port ( FAy/CLy )
HBA2 - port 1 ---------> Fabric B --------> Storage port ( FAt/CLt )
the zone which is in your output is VSAN 1. if its a production VSAN, Cisco doesn't recomends to use VSAN 1 ( default vsan ) for production.

No.I found my SAN set up NOT having Two idependent fabric. I found WWN of FabricName on Configuration Tab on
Domain Manager is same on both 9124s.I think, I am thinking on right track..correct me if I am wrong!!
If wrong, How to check whether it is a Single Fabric or Dual Fabric..Thanks RAMU & Kenk.
