Oracle Database Discussions

Hi all,

I want to install RAC database (oracle 10g on RHEL5). Now we are configurind shared storage for the both servers (nodes). In disk configuration (SAN on EVA 4400) we have created the volume group for the disk to use for ASM and present the disk group to the servers. Actually when we check the server we cannot see the disk (shared storage).

[root@cdr-analysis01 ~]# ls /dev/cciss/ -lR
/dev/cciss/:
total 0
brw-r----- 1 root disk 104, 0 Jul 1 2009 c0d0
brw-r----- 1 root disk 104, 1 Jul 1 14:29 c0d0p1
brw-r----- 1 root disk 104, 2 Jul 1 14:29 c0d0p2
brw-r----- 1 root disk 104, 3 Jul 1 14:29 c0d0p3
brw-r----- 1 root disk 104, 4 Jul 1 2009 c0d0p4
brw-r----- 1 root disk 104, 5 Jul 1 14:29 c0d0p5
brw-r----- 1 root disk 104, 6 Jul 1 14:29 c0d0p6
brw-r----- 1 root disk 104, 7 Jul 1 2009 c0d0p7
brw-r----- 1 root disk 104, 8 Jul 1 14:29 c0d0p8

(they are local disks not the shared disk)

My questions are:
- How to mount the disk to be seen in the server
- How to configure the disk for ASM is there any document for this. In my knowledge the disk to use for ASM doesn't need to be formated with a file system and shouldn't see when we run the df command.

Does anybody can help me as it's very urgent for us.

Thank you
