Pinned topic Qlogic 8GB Pass-Through Module Load Balancing

‏2013-09-25T19:03:15Z |

Hello Everyone,

Having an issue implementing an FC load balancing configuration on a number of blade centers.   Here is the setup/environment.  We are using 2 FC ports per pass-thru module (external TF ports 0 and 15) connected directly to the core Cisco MDS 9506 with NPIV enabled.  The Bay 3 PT module connects to Fabric A switch and the Bay 4 PT connects to Fabric B switch.  The 14 internal ports (TH) are configured as follows:

Configuration Name: default
  Port Number: 1
  AdminState           Online
  LinkSpeed            Auto
  PortType             TH
  PrimaryTFPortMap     0,15
  BackupTFPortMap      None
  SymbolicName         Port1


The problem is that we are only seeing traffic on the external port 0 and nothing on port 15 on Bay3 and the oppisite on Bay 4.  Essentially we are only using 2 out of 4 FC ports.  This is obviously overloading those 2 ports.  According to the pass-through docs and IBM Redbook we should be able to assign multiple TF ports to each TH port for a load balance (active/active) setup instead of the default  Primary  0,  Backup 15. (fail-over)  btw,   we made the configuration changes, save it and activated.  Any insights would be greatly appreciated.  Thanks!
