Hi all. Has anyone developed a shell script to place a Media Agent into maintenance mode and stop services? I’m trying to cobble something together without hard coding credentials when running qlogin at the beginning of the script.

I essentially need to run:

./qoperation execscript -sn setMediaAgentProperty -si mediagent -si 8 -si 1

commvault stop

Are you concerned about the password because you want to create a script that multiple users can execute but you don’t want them to see the password?  We can resolve this using sudo.

Create the scripts, chmod 700 the scripts, and config /etc/sudoers so users can run them.

Here’s an example I created of a script that runs “commvault status”.  My user cannot access the script to see what’s inside, but my user can run the script.  Does this address your concerns?

$ cat /root/status.sh
cat: /root/status.sh: Permission denied

$ sudo /root/status.sh | grep Version
 Version = 11.25.9

Thanks,
Scott

You can generate an encrypted token file and use that to authenticate for each command

Yes! Sorry for the late reply. We’re going to test this out in our lab and I’ll report back.
