Hi,
I''m trying to disconnect some iSCSI targets, but can''t seem
to.
[root@localhost ~]# iscsiadm -m session
tcp: [1] 192.168.2.202:3260,1 iqn.2011.01.22.freenas.nvr:500gb
tcp: [3] 192.168.2.200:3260,1 iqn.2011-2.za.co.securehosting:RAID.thin3.vg0.1tba
tcp: [4] 192.168.2.202:3260,1 iqn.2011.01.22.freenas.nvr:extent0
tcp: [5] 192.168.2.200:3260,1
iqn.2011-2.za.co.securehosting:RAID.iscsi0.vg0.500gb
I need to disconnect all 4 of these
[root@localhost ~]# iscsiadm -m node -T 192.168.2.200:3260,1
iqn.2011-2.za.co.securehosting:RAID.iscsi0.vg0.500gb -p 196.34.136.200
--logout
The target is still there, even though I tell it to disconnect.
[root@localhost ~]# iscsiadm -m session
tcp: [1] 192.168.2.202:3260,1 iqn.2011.01.22.freenas.nvr:500gb
tcp: [3] 192.168.2.200:3260,1 iqn.2011-2.za.co.securehosting:RAID.thin3.vg0.1tba
tcp: [4] 192.168.2.202:3260,1 iqn.2011.01.22.freenas.nvr:extent0
tcp: [5] 192.168.2.200:3260,1
iqn.2011-2.za.co.securehosting:RAID.iscsi0.vg0.500gb
I can''t delete it either:
[root@localhost ~]# iscsiadm -m node --op delete --targetname
192.168.2.202:3260,1 iqn.2011.01.22.freenas.nvr:500gb
iscsiadm: no records found!
Restarting iscsi gives some odd errors:
[root@localhost ~]# /etc/init.d/iscsi restart

Interestingly, the targets which iscsi reports as not existing, does exist:

Is there any other way to force these disconnects, and re-connect them?

If you''re desperate, I seem to recall something being written to /var/lib/iscsi. Deleting/moving away everything under nodes/ and send_targets/ might be worth a shot (do so at your own risk though). Another thing that might help, Googling "iscsi-initiator-utils prevent auto login" gives http://www.idevelopment.info/data/Unix/Linux/LINUX_ConnectingToAniSCSITargetWithOpen-iSCSIInitiatorUsingLinux.shtml , search for "Delete Target and Disable Automatic Login" which might help you (also do so at your own risk). Again, this isn''t related to Xen, so if you still have problems better ask on Centos list/forum, open-iscsi list/forum, or buy Redhat support. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] can''t disconnec iSCSI targets, please help
Hi Rudi,
logout from individual targets:
# iscsiadm -m node -p ''192.168.2.200:3260'' --logout -T
''iqn.2011.01.22.freenas.nvr:500gb''
no more auto-login:
for newly discovered targets:
/etc/iscsi/iscsid.conf
...
node.startup = manual
...
for the known targets check:
find /etc/iscsi/ -type f -exec grep -H startup \{\} \;
I don''t know of the top of my head if you need to change the old target
config files or if
it is enough to change the default in /etc/iscsi/iscsid.conf and do a discover
again.
cheers

But, your tip helped. I had to remove the entries from /var/lib/iscsi/send_targets/ So, the problem is no solved, thank you :) -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
