Hello All,
I am using rhel5.2 with OFED 1.3.1 drivers for linux, and noticing that
the initiator is unable to connect over iSER. My question is - is iSER
support available in 1.3.1? When I try and connect using ipoib address,
I get a connection failure. I am using Sun x64 comstar iSCSI target
(with iser transport) and rhel5.2 as the initiator.
Here's what I did from the rhel5.2 initiator:-
(all of these commands succeeded without errors or warnings)
# iscsiadm -m node -T

192.168.0.5:3260,1 -o update -o update -n
node.conn[0].iscsi.HeaderDigest -v None
During login/discovery I see the following error message -

I can connect to the iSCSI target using sockets, but iser transport
seems to be having problems.
Am I missing something here? is iSER transport available in v1.4?
thanks,
