Is it possible to start the package in the second node without shutting down the second system by using cmrunpkg command.And what abt the data if we are staring by using cmrunpkg will it led to any data loss.Or we need to use any other command

Hi Kamal,

If the Auto-switching was disabled before the primary server went down, then the package will not start on the adoptive server.

You can run the package from the adoptive node by enabling the switching on that node.

# cmmodpkg -e -n

Then you can do

# cmrunpkg -v

The filesystems will be fsck'ed before mounting and hence should not cause any data loss in most of the cases.

Try this out and let us know the result.

Cheers,
Mohan.

Kamal,
When auto switching is disabled, packages will not shift to secondary server. You have two options before you:

1. # cmmodpkg -e -n pkg1
This will enable the switching.
Or
2. When primary server goes down you need execute following on secondary:
# cmmodpkg -e -n pkg1
# cmrunpkg -n pkg1
This will enbale the package on secondary and will be able to run on secondary server.
Hope that helps.

Regards,
