If you're wrong about the IQN and/or dataport, it's not going to work. I think you want: iscsiadm -m node -u And for good measure: iscsiadm -m session -u If you do want to delete specific discovery records and need to identify the dataport associated with them: iscsiadm -m discoverydb ... will print them. > The target is still there, even though I tell it to disconnect. > > [root at 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 at 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: If you're going to that extent, you can umount all remote targets, disable iscsid and iscsi services, reboot, and clear out the various entries under /var/lib/iscsi/. Leave the directories (/var/lib/iscsi/*/), but remove the files beneath them. Note that this is a bit like doing brain surgery with a sledgehammer. Lacking in finess, but for some jobs, effective. You might also try posting to the open-iscsi mailing list. I've found that iscsi is very tempermental and poorly understood by most. -- Dr. Ed Morbius, Chief Scientist / | Robot Wrangler / Staff Psychologist | When you seek unlimited power Krell Power Systems Unlimited | Go to Krell!
