It is a SAN via Ethernet. Set up the iSCSI requester, but not on an iSCSI adapter, just an Ethernet adapter that runs iSCSI protocol.
The disk is shown as iSCSI device. Upon which I created the volume group, and filesystems. (not an NFS share or any think like that, all Unix native.)
When the problem occurs, the SAN says AIX is not logged into the SAN (No connection - requester security is minimal, I only restrict by IP - but I could change that to IQN name. But I'm not using CHAP or any other password authentication.)
At the same time, AIX shows the file systems on the SAN as mounted. Shows the VG as active and the disk as there. An attempt to dismount the filesystem or any other activity is usually followed with a long timeout or hanging process. Sometimes I get device not responding messages.
If I could figure out how to get the AIX to re-establish the connection to the SAN, I would assume at that point I could then mount / dismount. filesystems.
