A question for /etc/tgt/targets.conf

[arjunlin]

Hello All ,

I had a problem with iSCSI target service when I tried to reboot my server.
Before reboot server, the iSCSI target services status is okay,and I can use the TD5 drives on windows well.
But after system rebooting ... the tgtadm show me nothing...
Is there any issue with it ?

PS. I know another solution to run tgtadm command in /etc/rc.local .

It's my opration as bellow.Thanks a lot.

Unless some here can help with tgt, I recommend contacting tgt developers at [e-mail] or check their website http://stgt.sourceforge.net. Also, if you are not running a recent version, you may want to check for updates at https://github.com/fujita
