I am having an issue adding a share to a new AFS instance where it reports “iSCSI discovery of targets failed to iSCSI portal xxx.xxx.10.5. Ensure that the stargate external data services IP and the CVM IPs are reachable from FSVM.”

I have confirmed the CVM IP’s and FSVM IP’s are all bound to the eth0 interface of there respective devices and are all in the same xxx.xxx.10.xxx network segment.  All devices can ping all IP’s in the range so at least basic comms are working.

I am sure I am missing something obvious but not sure where to go from here.  Suggestions please!
