Description Brett Thurber 2012-12-10 14:39:47 EST

Description of problem:
In RHEVH console, under Remote Storage Configuration, change the intiator name on the RHEVH host.  Without rebooting RHEVH, try and connect to a iSCSI target.  Initiator name on the storage device is identified as the original name for the RHEVH host, not the updated name.  A reboot of the RHEVH host resolves this.

Version-Release number of selected component (if applicable):
3.1 GA
RHEV Hypervisor - 6.3 - 20121121.0.el6_3

How reproducible:
Every time.

Steps to Reproduce:
1.  Change the initiator name on the RHEVH host.
2.  Connect to a iSCSI target.  Observe the initiator name used was the original, not the new name. 
3.  Reboot RHEVH host to resolve initiator name change.
  
Actual results:
Initiator name change in RHEV console does not take affect until a reboot.

Expected results:
Initiator name change in RHEV console should be immediately persistent without a reboot.

Additional info:
N/A

Comment 1 Mike Burns 2012-12-11 11:47:46 EST

NOTE:  this is for filing upstream ovirt-node bugs, not RHEV-H bugs.  Those should go through a support case with Red Hat.

The bug itself will likely apply to ovirt-node iso images as well, so I'll keep it open.

Joey -- probably just a matter of restarting the right iscsi daemon after making the change.

Comment 2 Joey Boggs 2013-01-21 22:22:56 EST

looks to be a problem with the iscsi service starting and only in RHEV-H moving there

[root@localhost ~]# service iscsi status
No active sessions
[root@localhost ~]# service iscsi restart
Stopping iscsi:                                            [  OK  ]
[root@localhost ~]# service iscsi status
iscsi is stopped

-----------------
commenting out the below and finishing out the init script start function

    # if no nodes are setup to startup automatically exit cleanly
#    grep -qrs "node.startup = automatic" /var/lib/iscsi/nodes
#    [ $? -eq 0 ] || exit 0



-------------------
[root@localhost ~]# service iscsi restart
Stopping iscsi:                                            [  OK  ]
Starting iscsi: iscsiadm: No records found
                                                           [  OK  ]
[root@localhost ~]# service iscsi status
No active sessions

Comment 6 Chris Leech 2013-01-24 20:07:06 EST

I'm guessing that all the management console is doing is editing /etc/iscsi/initiatorname.iscsi ?  Unfortunately iscsid will not pick up changes without a restart.

Also, in comment #2 there are references to the iscsi service.  The iscsi service is for bringing up persistent sessions configures as automatic.  What needs to be restarted is the iscsid service.
