We have blade server that using Brocade SAN switch connected to DS5200. As sys admins asked more space for blades I have connected Storwize v3700 via 4 FC ports to the Brocade SAN switch. Blade has two HBAs. I haved zoned appropriate ports. So I tried to add host and therefore WWPNs to storwize but it coudn't find these port by RESCAN button. When I tried to add them manually, It has showed one port as "degraded" and onother as "offline" state. Anyway Linux OS which runs inside the blade could see the LUNs, and as we mounted it's worked.
Why these ports doesn't seem as ACTIVE instead of DEGRADED or OFFLINE?
