Hi members, I tried to do the following to find out the error messages: Both systems with iscsitarget/open-iscsi initiator and open-iscsi initiator were up. On the open-iscsi initiator i had opened a terminal with command tail -f /var/log/messages and left it running And then i rebooted the server with iscsitarget/open-iscsi initiator
And all i could see were ocfs2_dlm node 0 leaves domain nodes in domain : 1 and then it hangs again so i had to manually hard reset the server I tried to boot with runlevel 2 but there were not much of a use because there were no specific error messages to this scenario, i Checked /var/log/messages and /var/log/boot.omsg But i'm still able to ping the open-iscsi initiator system on its hang. But when i try to rsh or ssh to the system, nothing happens. I haven't setup multipath yet. @mike I have setup ocfs2 file system on a partition(on secondary hard drive on iscsitarget/open-iscsi initiator box) which is being mounted as /u01/orcl on both boxes. So i think i have nbd(not sure if my setup is supposed to be called as nbd). When i tried rciscsitarget stop on iscsitarget/open-iscsi initiator box, both the iscsitarget/open-iscsi initiator box and open-iscsi initiator box hanged. Again a hard reset. How do i get a serial line or have a console hooked up somewhere on the box that hangs to get a trace? may be if you could send me a link on how to set this up? Appreciate all your sincere efforts to help me out.
