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!

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.

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 INFO: Query Returned: grid0 INFO: Calling Query fileQueries10.1.0.2.0 exists filename = /dev/sda2/ INFO: Query Returned: true INFO: Calling Query ClusterQueries10.2.0.1.0 IsItDir PathName = /dev/sda2/ INFO: Query Returned: false INFO: Calling Query cfsprereqQueries10.2.0.1.0 isOHonCFS oraclehome = /dev/sda2/ nodeList = grid0,grid1,grid2,grid3, localNode = grid0.hprsn.com INFO: Query Exception: RuntimeException Query Exception Class: class oracle.sysman.oii.oiil.OiilQueryException INFO: false INFO: Calling Query ClusterQueries10.2.0.1.0 IsItRaw PathName = /dev/sda2/ INFO: Query Returned: OPENFAILONDEV SEVERE: The location /dev/sda2/, entered for the Oracle Cluster Registry (OCR) is not shared across all the nodes in the cluster.
