I just setup a 10.2.0.4 2 nodes RAC on RHEL 4.4 running right now with these
disks and primary partitions:
fdisk -l | grep "\/dev\/sd[a-z]1"
/dev/sda1 * 1 2611 20972826 fd Linux raid
autodetect
/dev/sdb1 * 1 2611 20972826 fd Linux raid
autodetect
/dev/sdc1 2 26109 209707008 83 Linux /dev/sdd1 2 26109 209707008 83 Linux /dev/sde1 8193 262144 253952 83 Linux /dev/sdf1 117 7437 516096 83 Linux /dev/sdg1 8193 262144 253952 83 Linux /dev/sdh1 8193 262144 253952 83 Linux /dev/sdi1 117 7437 516096 83 Linux /dev/sdj1 2 26109 209707008 83 Linux /dev/sdk1 2 26109 209707008 83 Linux /dev/sdl1 1 16810 135026293+ 83 Linux
You can have many primary partitions just that you can have up to 4 per disk (that is per lun in your case)
Thanks
