Alan, the sysadmin has previously allocated the LUNS, multipath driver is in place. I do plan to configure this with udev. However, the Grid Infra Install Guide seems to be scsi, I copied the section below. We will look for IBM docs on this topic, if anyone has info please let me know.
To configure a permissions file for disk devices, complete the following tasks:
To obtain information about existing block devices, run the command scsi_id
(/sbin/scsi_id) on storage devices from one cluster node to obtain their
unique device identifiers. When running the scsi_id command with the -s
argument, the device path and name passed should be that relative to the sysfs
directory /sys (for example, /block/device) when referring to
/sys/block/device. For example:
# /sbin/scsi_id -g -s /block/sdb/sdb1

Don,
Have you looked into udev and device mapper? I've deployed 5 RACs on RHEL 6 using device mapper with 3PAR storages. The Multipath configuration is a bit tricky, but very well documented both by HW vendores and Oracle itself. I suggest you talk to a sys admin as they should know what do with device mapper and udev in order to present the disks to you in an easy to use fashion (i.e. using /dev/mapper instead of the /dev/dm-###)
