Ganesh,

You ask:
"How to move running pacakge to secondary node without any dusruption in service?"

What disruption of service are you referring to?

If you are referring to the application the package is running, moving that package to another server WILL cause an interruption of service because
a) the new server must activate resources the application will need, including fsck, mount etc.
b) application recovery time if any
c) users will have to connect to the new server to access the application.

Hi Ganesh,

You just can't switch the package _without_ any disruption to the service. But, to speed up the package switch, you can do the halt and the start phase from the command line like this:

# cmhaltpkg PKGNAME; cmrunpkg -n ONWHICHNODE PACKAGENAME

This way the start will be initiated right after the stop.

Viktor
