How to create raw partition?
Hii,
I am going to install Oracle 10g RAC on Solaris 10 (sparc) using Oracle Clusterware only.I am not going to use any vendor provided clusterwares.
For Oracle Clusterware installation,I need five raw devices.
I am using Sun StorEdge T3.I want shared storage on two nodes of cluster.I have created necessary raw devices by Format command followed by Partition.After that I have set appropriate permission.But this permission is not reflets in ls command.
So How I can create raw partitions?
Plz give me detailed steps

How did you change the permissions on the device nodes?
chown oracle /dev/rdsk/.... ?
If so, this won't have changed the actual device node as /dev/rdsk/ entries are symbolic links to device nodes residing under /devices
If you run ls -lL /dev/rdsk/c.t.d.s. you'll see the what the details for the device node are.
ls -l /dev/rdsk/c.t.d.s. will show you what the link points to.
e.g.
# ls -l /dev/rdsk/c1t0d0s7
lrwxrwxrwx1 rootroot 58 Apr 24 17:18 /dev/rdsk/c1t0d0s7 -> ../../devices/pci@7c0/pci@0/pci@1/pci@0/ide@8/sd@0,0:h,raw
# ls -lL /dev/rdsk/c1t0d0s7
crw-r--1 rootsys32, 23 Apr 21 00:46 /dev/rdsk/c1t0d0s7
# chown oracle /devices/pci@7c0/pci@0/pci@1/pci@0/ide@8/sd@0,0:h,raw
You'll have to make sure that this is done on all the nodes in the cluster.
Depending on your local admin policy, you may want to look at /etc/minor_perm and to modify the sd or ssd entries so that any disk added will have the correct modes. Having said that, it's unlikely you'll want oracle to have write access to EVERY raw disk.
