By offline, did you mean the disk was offline on the target side? if so, do you know what type of target you're using open-iscsi against? If that is iscsi enterprise target, you can edit the configure file / etc/ietd.conf on the target side properly and restart the target service by "/etc/init.d/iscsitarget restart".
Also you can check this out and see if it can help a bit (it's for ubuntu but the set up process should be similar on your linux distro): http://www.howtoforge.com/using-iscsi-on-ubuntu-9.04-initiator-and-target On Apr 21, 5:42 am, "Dominique Cressatti" <[email protected]> wrote: > I've figured it out.
