You said you have no link, but the link between adapter and switch should normally established, independent of your storage system.

Can you please repeat the "SAN Zone support" step and verify the link activity (if yellow light start flashing or not) on the failed adapter? In case of no activity, and under assumption you already twist and replace the cable, i guess the adapter is broken.
Yes, no link,connectivity,communication to the fabric switch. SAN guys cannot establish a "link" or "connectivity" from the adapter to the switch.
I will go out tomorrow and do "SAN Zone Support" and re-plug the fibre cable.
I just don't know how the adapter can be broken...it's possible, but improbable that 3 x dual port fibre adapters have 'failed'.
Like I mentioned, upon rmdev the devices and cfgmgr and the adapters coming back fine, don't show me an indication that the adapters could be faulty. I even ran a diag test and no issue. I have no evidence to say its a hardware fault. I just don't know. Last case scenario, try another PCI-x slot and get an IBM engineer to come out and replace the adapter. If the new adapter installs fine, and still same issue, it's definitely the SAN team issue. SmilieSmilieSmilie

Oh on another thought X-ray, what happens if on the switch the port comes up as FE - Fabric Extender? Sometimes the yellow light came on the adapter, but will not display the luns to the VIOS server (secondary server).

NAME
scconf_transp_adap_qfe - configure the qfe transport adapter DESCRIPTION
Note - Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor- mation about the object-oriented command set, see the Intro(1CL) man page. You can configure qfe Ethernet adapters as cluster transport adapters. These adapters can only be used with transport type dlpi. The qfe Ethernet adapter connects to a transport switch or to another Ethernet adapter on a different node. In either case, the connection is made through a transport cable. When a transport switch is used and the endpoints of the transport cable are configured by using scconf, scinstall, or other tools, you are asked to specify a port name on the transport switch. You can provide any port name, or accept the default, as long as the name is unique for the switch. The default is to set the port name to the node ID hosting the adapter at the other end of the cable. There are no user configurable properties for cluster transport adapters of this type. SEE ALSO
