Dear All,
I have executed delete operation on a target for nodes database when some
sessions are active. Now, when i execute following command, i get below
error message.
[root@HN0101 ~]# iscsiadm -m session

iscsiadm: could not read session targetname: 5
iscsiadm: could not find session info for session3076
I have used RHEL 6.6 linux distro and my open iscsi initiator version
is iscsi-initiator-utils-6.2.0.873-13.
In my environment, we have a RPC XML server which is written in python.
When a client request for a operation(say operation1), we execute following
iscsiadm command in sequence using Popen() interface of subprocess module
in some portion of the operation,
1> Logout all session for all target, Command - "/sbin/iscsiadm --mode
node --logoutall=all"
2> modify iscsi.conf file
3> restart iscsid.
4> run discovery on all portals of storage device.
If discovery fails on all portals(N/W down or other reasons),
then delete the nodes database for each target using iscsiadm utility.
Now, after above error has occurred, when we go to execute operation1, My
server generates core. The core is generated by iscsiuio.
Can any one help me to understand the cause of the problem.
