function customer_defined_run_cmds
{
cmmodpkg -d -n 'hostname' pkg02 &
}
The function customer_defined_run_cmds calls the cmmodpkg command with the package
control option (-d). This command prevents the host that is running pkg01 from adopting
pkg02. The ampersand (&) causes the cmmodpkg command to run in the background. It must
run in the background to allow the control script to complete.
There is a short time, after one primary node has failed but before the cmmodpkg command has
executed, when the other primary node can fail and the adoptive node will adopt its package.
In other words, if both thyme and basil fail at approximately the same time, host sage may
adopt two packages, even though the package control option is specified.
If you omit the cmmodpkg -d command from the NFS control script, host sage can adopt both
pkg01 and pkg02 if their primary nodes fail.
