Big Problem...NO DISKS ON IET RESTART

1. "open-iscsi(865-0.2)" initiator machine connected to 1 target from target machine(having "IET version 16.1").

2. output of "iscsiadm -m session -P 3"

iSCSI Transport Class version 1.1-646
iscsiadm version 2.0-865

3. When I restarted "iscsi-target" daemon on the target side,Disk on the initiator got "blocked" and took tooooo much time to recover.

4. When Disk state was "running" after toooo much time,it's status still was,

                        iSCSI Connection State: IN LOGIN
                        Internal iscsid Session State: REPOEN
    making disks inaccessible on the initiator side,
 
    It should be

                         iSCSI Connection State: LOGGED IN
                         Internal iscsid Session State: NO CHANGE

here's how it is.....

                scsi17 Channel 00 Id 0 Lun: 0
                        Attached scsi disk sdg          State: blocked

          After some time only last line changes to
                        Attached scsi disk sdg          State: running

          But still disks are inaccessible on initiator side.

          So IET code need to changed for that?
