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
