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.
