Hi tony, are you using OS raw storage or ASM?  For the latter I simply check OS processes.

$ ps -ef |grep pmon
grid      7479     1  0 Mar20 ?        00:00:12 asm_pmon_+ASM

Wouldn't the ps command posted above just confirm that ASM is running?

I assume you want to know if an instance is part of a RAC cluster?

If so try the following:
http://docs.oracle.com/cd/B28359_01/rac.111/b28254/admin.htm#RACAD920

Verifying That Instances are Running

To verify that instances are running, on any node from a SQL*Plus prompt enter the following, where password is the password:

CONNECT SYS/as SYSDBA
Enter password: password
SELECT * FROM V$ACTIVE_INSTANCES;

I don't understand how the accepted post answers the question.

ASM doesn't imply RAC.  We've got hundreds of databases on ASM but the vast majority of them are NOT RAC instances.

I'd try something like this from the command line

Check the cluster itself..

crsctl check cluster

or

crsctl check crs

Open in new window



 or, login and check v$instance as noted in the docs in the post from slightwv
