Well, I've got a working model which I'm not going to test at the moment. Our current thinking is that since the raw device (/dev/raw/rawN) is a virtualized device linked in to the underlying one (/dev/emcXXXX), perhaps the kernal did not immediately pass the permissions down the line. Doing the manual change to /dev/emcXXX and changing it back again gave it a kick to apply the changes. If I see this again I'll try restarting the rawdevices (/sbin/service rawdevices restart).

Subject: RAC installation conflagration

I'm working on a RAC installation (10.1.0.2) on RedHat LinuxAS3 with EMC Clariion shared storage. The EMC devices have been linked to raw devices. I can see them all if I run 'raw -qa'. They are also all entered in /etc/sysconfig/rawdevices. The problem comes when I am trying to create the Cluster Registry file in a raw device. What I get from OUI is a nondescript error "An error occurred when trying to execute the query". The permissions of the device are:

$ ls -l /dev/raw/rawN
Crw-rw---- 1 root oinstall /dev/raw/rawN

When I change the ownerships of the underlying EMC device (the one which was linked to the raw device in /etc/sysconfig/rawdevices) from root:root (660) to root:oinstall (660) everything works. Nowhere have I seen it mentioned to change the settings of this device, so I am wary in heading in this direction.

There is a little bit more information in the installActions.log
