zoning
Dears,
What would happen if the same HBA [pwwn] are zoned to two different storage array port ?
for an instance, the pwwn# of HBA is zoned to DMX port and also to IBM storage port.
what would be the impact to server in such case?
cheers

This one HBA will share it's maximum performance between the 2 arrays. I think you should consider if it's possible to have EMC Powerpath as well as IBM's loadbalancing software running at the same tmie. Is this possible ? Does IBM have software like this or can either one of the two perform this task for the DMX as well as the IBM array ?
I would in any case create 2 separate zones (for each HBA) and avoid zoning 1 HBA and 2 storage ports in the same zone. So zone1 = HBA + DMX port and zone2 = HBA + IBM port. So please avoid that a storage port can see some other storage port.
For the rest I can't think of any impact for the server.

Exactly, but you should indeed make sure both vendors support this config. Just to make sure.

I don't think there will be any impact...only thing wht will happen is that the server will see the LUNS from both the storage mapped to those ports.
