ASM Installation on Oracle 11g Clusterware (RAC) environment

Question

Hi All,
I am trying to setup Oracle 11g Standared Edition RAC+ASM on RedHat Linux 5.0 VM ware box. As part of this RAC setup successfully completed. For this i have used raw devices and mounted using NFS.
In many of forumns i have read that ASM installtion on a cluster envioronmnet is different than non cluster environment.
I dont know how to start ASM installtion on RAC environment. Please share any documents if you have?
Thanks,
Rakesh

Answer 1

will the steps need to be done on two nodes of cluster or it is sufficient on first node.
"raw device" for OCR, VOTE, SPFILE_FOR ASM and ASM DISKGROUPs
before do "raw devices" you have to fdisk(make partitions) on share storages
node1:
# fdisk /dev/sdf
# ls /dev/sdf*
node2:
# ls /dev/sdf*
don't find...,so just fdisk -> l and -> w
fdisk how? http://linux.about.com/od/commands/l/blcmdl8_fdisk.htm
Example: /etc/sysconfig/rawdevices do it every nodes
#Oracle OCR File +~280M+
/dev/raw/raw1 /dev/sdf1
#Oracle Voting File +~280M+
/dev/raw/raw2 /dev/sdf2
#Oracle ASM spfile ~50M+
/dev/raw/raw3 /dev/sdf3
#Oracle ASM DISK Group1
/dev/raw/raw4 /dev/sdg1
#Oracle ASM DISK Group2
/dev/raw/raw5 /dev/sdh1
And oracle user.. can read /dev/raw/raw* You should find on every nodes

ls -la /dev/raw/raw*
crw-rw---- 1 root oinstall 162, 1 Jan 13 12:53 /dev/raw/raw1
crw-rw---- 1 oracle oinstall 162, 2 Jan 13 12:53 /dev/raw/raw2
crw-rw---- 1 oracle oinstall 162, 3 Jan 13 12:53 /dev/raw/raw3
crw-rw---- 1 oracle oinstall 163, 1 Jan 13 12:53 /dev/raw/raw4
crw-rw---- 1 oracle oinstall 164, 1 Jan 13 12:53 /dev/raw/raw5
do it on node1 but you have to pass phrase on every nodes Before
http://www.puddingonline.com/~dave/publications/SSH-with-Keys-HOWTO/document/html/SSH-with-Keys-HOWTO-5.html
example:
node01:
$ ssh node01 hostname
node01
$ ssh node02 hostname
node02
- Install + Setup Clusterware:
OCR = /dev/raw/raw1
VOTE = /dev/raw/raw2
- Install Oracle Database for ASM Home
spfile for ASM = /dev/raw/raw3
- after ASM started... create disk groups from /dev/raw/raw4 and /dev/raw/raw5
- Install Oracle Database for RDBMS Home
- Create Database to use ASM diskgroups

Did you followed the same procedure to set up Oracle 11g RAC+ASM on RHEL 5.0.I'd done(test 11gRAC) it on RHEL 4 + 11g + ASM(on raw device)
on production, I use ASMlib... + ASM + 10g
you can read on metalink to help idea

Oracle 11g’s RAC.. I think.. that can help you ;)
Good Luck

Example from IBM... Deploying Oracle RAC 11g R1 on RHEL 5 or SLES 10 with Oracle ASM on the IBM DS3400, DS4200, DS4700, and DS4800 Storage Subsystems
