RE: 10g RAC Install with Raw Devices

Hey Bill,

You are correct. The permissions were not correct. The oracle user had rwx but was not in the group ownership of the actual device. Once we got that fixed and modified the init scripts to change the ownership on reboot, the install when fine (until running root.sh where we had another problem...).

Thanks for all of the help guys!

Todd

Todd,

Check the ownership on your raw devices. In order for the install to work ownership must be oracle:oinstall, or oracle:dba if you haven't created the oinstall group. If it is root:root then the installer will fail. I believe that is the error I saw prior to realizing the correct setting of ownership.

Thanks.

Subject: 10g RAC Install with Raw Devices

Hey Guys,

I am doing a RAC install on an x86_64 RH4 box. We are using 10.2.0.1 and raw devices. The SAN is a MSA 1500. The issue that I am having is during the Cluster install. The installer is complaining that all nodes can't see the raw device location that I point it to for the OCR. I can dd from all nodes to the device. Has anyone seen this before? Does anyone know what test Oracle is using to determine connectivity? Are there any other options that I should try before creating an SR?

hostName = grid0.hprsn.com

SEVERE: The location /dev/sda2/, entered for the Oracle Cluster Registry

Thanks!
