How do you know it didn't?

There are some problems with your script:

The monitor (status):

node2/ha-log.txt:May 28 11:29:31 node2 lrmd: [10638]: info: RA output: (scriptHa:monitor:stderr) /etc/init.d/scriptHa.sh: line 39: [: 21852: binary operator expected 

Looks like the script can't stop whatever it's controlling:

node2/ha-log.txt:May 28 11:29:35 node2 lrmd: [10638]: info: rsc:scriptHa: stop
node2/ha-log.txt:May 28 11:29:35 node2 lrmd: [10638]: info: RA output: (scriptHa:stop:stdout) Stopping RSC-TEST...
node2/ha-log.txt:May 28 11:29:35 node2 lrmd: [10638]: info: RA output: (scriptHa:stop:stderr) /etc/init.d/scriptHa.sh: line 14: [: 21852: binary operator expected /etc/init.d/scriptHa.sh: line 18: kill: (27850) - No such process 
node2/ha-log.txt:May 28 11:29:36 node2 lrmd: [10638]: info: RA output: (scriptHa:stop:stdout) .. Done. 
node2/ha-log.txt:May 28 11:29:46 node2 lrmd: [10638]: info: rsc:scriptHa: start
node2/ha-log.txt:May 28 11:29:46 node2 lrmd: [10638]: info: RA output: (scriptHa:start:stdout) RSC-TEST is already running, PID=27857 

In short: look for lrmd:.*scriptHa in the logs and try to figure
out what's going on.

Thanks,

Dejan
