I have been trying to read up on the forums and elsewhere but am getting more confused as I go along.
I have an HP-UX 11.23 server and have installed the iscsi initiator. We have loaned an intel-based storage system which has ISCSI on it (to do a POC). I have done all kinds of things on the HP server to try and access the storage system but am now more confused than ever.
obelix2:/ (root) $ iscsiutil -p

Re: ISCSI SETUP ON HP-UX
I have also done all the and that process is running.
I do however see the following in the syslog:
Oct 13 13:18:53 obelix2 vmunix: 255/0: Invalid iSCSI Name format (iqn.2008-10:dss.target0) received from the target.

Re: ISCSI SETUP ON HP-UX
Re: ISCSI SETUP ON HP-UX
--> Invalid iSCSI Name format (iqn.2008-10:dss.target0)
Verify that the iSCSI Name is valid.
The iSCSI Initiator Name or iSCSI Target Name is referred to as an iSCSI Name. The iSCSI Software Initiator configures a default Initiator Name in the "iqn" format. If you have changed the Initiator Name from its default using iscsiutil and the Initiator Name is in an invalid format, iSCSI login negotiation could fail leaving target devices inaccessible from the HP-UX host.

which it did not show erlier, and no more errors in the syslog.
The next step ioscan -fnC disk still does not show it...
Any other ideas?
