I have an issue trying to get an HP NC551 i CNA adapter to talk to our NetApp FAS3140. We have a rack mount server using Microsoft iSCSI software initiator that is able to access the FAS3140, but our blade servers can't.
The rackmount server can ping both the NetApp and the HBA on the blades.
The NetApp can ping the rackmount server iSCSI IP but not the HBA's
The blade server are able to ping the rackmount servers (and also some other blade servers using standard NIC's for iSCSI) but not the FAS3140.
Has anyone got any ideas what may be causing the issue. Not sure if it's a server or NetApp issue as devices other than the NetApp are able to communicate with the HBA's.
We gave up in the end. Seems the CNA card is supported for FCoE (or so my colleague said) but not for iSCSI. HP have just released firmware updates for the CNA & Flex10 interconnect modules not sure whether that would resolve the issue, though still wouldn't be a supported config.
We decided to use standard Flex10 NIC's rather than the iSCSI HBA's and use the MS iSCSI software initiator which we've had no issues with.
