nohup process hangs
Hi All,
I tried searching for this, but I have yet to find anything useful. So here goes,
if a script executed from another script with nohup & hangs, does it affect the parent script? Reason I ask, we have a windows box with NFS, and we use it to store some of our files. Currently, I mount the NFS directories, using a script from the command line, after a reboot. I would like to automate this, but typically the windows box is rebooted at the same time, and if the mount gets executed prior to the windows box boot, the script hangs. I know nohup'ed processes ignore hang ups, but what happens if they hang? Any knowledge and/or guidance will be greatly appreciated.

cmhaltserv
cmhaltserv(1m) cmhaltserv(1m)
NAME
cmhaltserv - halt a service from the high availability package halt script
SYNOPSIS
cmhaltserv [-v] service_name
DESCRIPTION
cmhaltserv is used only in the high availability package halt script to halt a service.
To stop a package service, the running package halt script must be running as superuser(UID=0), or as a user with access policy of
FULL_ADMIN allowed in the cluster configuration file. See access policy in cmquerycl(1) or cmmakepkg(1).
If any part of a package is marked down, the package halt script is executed as part of the recovery process.
This command sends a SIGTERM signal to the PID and the corresponding process group of the monitored service. If this signal is caught by
the running application, it is up to the application to ensure that the processes will be terminated.
Options
cmhaltserv supports the following options:
-v Verbose output will be displayed.
RETURN VALUE
cmhaltserv returns the following values:
0 Successful completion.
1 Command failed.
EXAMPLES
To halt the service db1, do the following:
# Halt the service db1
cmhaltserv db1
This line should only be executed within a package halt script.
AUTHOR
cmhaltserv was developed by HP.
