| Doc Text: |
Due to changes in the addressing of inter-process communication (IPC) sockets, updating the isciadm administration utility caused it to be incompatible with the already-running iscsid processes. As a consequence, iscsiadm could no longer communicate with the running iscsid processes after the update. This update adds a retroactive compatibility IPC mode, which automatically triggers when a new IPC socket fails to connect. As a result, iscsiadm can now correctly be used to control pre-existing iscsid processes after an update.

(In reply to Meni Yakove from comment #0) Is it possible that you have an iscsid process running from an older package, with a newer iscsiadm after updating the package? Could you try restarting iscsid?

Could you try > restarting iscsid? It's seems that is the issue, I updated to iscsi-initiator-utils-6.2.0.873-8.el6.x86_64 and after reboot I can run discovery. When trying to restart iscsid service I got: Not stopping iscsid: iscsi sessions still active [WARNING] so the only way is to kill all iscsid processes or reboot the host. Not sure this is entirely not a bug. I also experience this issue. After upgrading from iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm to iscsi-initiator-utils-6.2.0.873-10.el6.x86_64.rpm you can see in a strace output we can no longer connect to the iscsid socket via a Connection refused when I run iscsiadm -m session -P 3.

Additional information, after removing the following patch: iscsi-initiator-utils-aligned-all-socket-comm-between-iscsiadm-iscsid-and-.patch
I was able to update from iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm to my own rebuilt rpm without the iscsi-initiator-utils-aligned-all-socket-comm-between-iscsiadm-iscsid-and-.patch patch.
