OCR initialization failed accessing OCR device: PROC-26
I am having some problem in my Linux Cluster. I setup Two linux boxes sharing same hard disk (Firewire drive). I configured Oracle 10g RAC on it. It was working fine, but starting last week, my machines are keep on rebooting if I turn on my firewire drive. If I unplug my firewire drive, then both machines are not rebooting by itself.
I checked /var/log/messages file and got following error in there..
ep 5 03:18:18 rac2 su(pam_unix): session opened for user oracle by (uid=0)
Sep 5 03:18:18 rac2 su(pam_unix): session closed for user oracle
Sep 5 03:18:18 rac2 logger: OCR initialization failed accessing OCR device: PROC-26: Error while accessing the physical storage Operating System error [No such device or address] 
Any idea what's wrong here????
Please help me.
