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

Setting the 'TitleLabel' property to 'Oracle Cluster Registry'.
Setting the 'SubTitleLabel' property to ''.
Setting the 'Prompt' property to 'The Oracle Cluster Registry (OCR) stores

cluster configuration and cluster database configuration. Specify a shared raw device, or cluster filesystem file that will be visible by the same name on all nodes of the cluster.
An OCR will be created for you., and will require approximately 100MB of disk space.'.

Setting the 'TextLabel' property to 'Specify OCR Location :'.
Setting the 'BottomDescLabel' property to ''.
Setting the 'TextField ( s_ocrpartitionlocation )' property to

'/dev/raw/rawN'. Received the value from the UI page.

Anyone else ever see this?

Thanks.
