Problem with "srvctl stop instance -o immediate"

Here are what happened today:

1 I tried to stop rac1 RAC instance.  Before stop the instance, I checked the instance status:

C:\Documents and Settings\Administrator>srvctl status database -d rac

Instance RAC1 is running on node site1-rac01

Instance RAC2 is running on node site1-rac02

2 Stop rac1 instance

C:\Documents and Settings\Administrator>srvctl stop instance -d rac -i rac1 –o immediate

PRKP-1002 : Error stopping instance RAC1 on node site1-rac01

CRS-0216: Could not stop resource 'ora.RAC.RAC1.inst'.

3 Check rac1 instance status:

C:\Documents and Settings\Administrator>srvctl status instance -d rac -i rac1

PRKO-2015 : Error in checking condition of instance on node: site1-rac01

4 Tried to start the instance:

C:\Documents and Settings\Administrator>srvctl start instance -d rac -i rac1

PRKP-1001 : Error starting instance RAC1 on node site1-rac01

CRS-1028: Dependency analysis failed because of:

CRS-0223: Resource 'ora.RAC.RAC1.inst' has placement error.

5 Check rac2 instance status:

C:\Documents and Settings\Administrator>srvctl status instance -d rac -i rac2

Instance rac2 is running on node site1-rac02

6 Stop rac1 instance by using “abort” option, it works without any error.

C:\Documents and Settings\Administrator>srvctl stop instance -d rac -i rac1 -o abort

7 Start rac1 instance without any errors:

C:\Documents and Settings\Administrator>srvctl start instance -d rac -i rac1

8 Check both rac1 and rac2 instances status:

C:\Documents and Settings\Administrator>srvctl status instance -d rac -i "rac1,rac2"

Instance rac1 is running on node site1-rac01

Instance rac2 is running on node site1-rac02

Lessons learned:

When stopping a RAC instance in Windows 2003 R2 platform, srvctl command with “-o immediate” option doesn’t work, use “-o abort” option instead.
