Our ESXi 5.0 U1 hosts are talking to the MD3220i fine without authentication, could someone help me set up CHAP please? I think it's needed in a production environment.
My first problem is: the MD3220i needs only a CHAP secret. But ESXi needs a name as well as a secret. What do I choose for the name? I can't leave it blank.
In ESXi I've tried ticking the check box to use the initiator name, and pasted the same secret as on the SAN (this is for target authentication only). ESX failed to connect with error "The iSCSI Initiator could not establish a network connection to the discovery address". I get the same if I try mutual authentication. If I undo the CHAP config everything's ok again.
The host has been set up in the MD3220i, and the host's IQN is the same in SAN and ESX. This was done before any LUNs were created, I think it's a necessary step before setting up storage shared between hosts in a "host group", as the SAN calls it.
So now I'm not sure what to do, any help gratefully received!
Thanks,
Matt
