DEV: disabling serverstat off and cycle for drp nodes

[KaushikMalapati]

Description

Trying to turn off or power cycle a drp node (a server with drp in its hostname) will instead point you to a confluence page explaining how to do this through the ipmi web interface and exit because using serverStat/psipmi sometimes causes the ipmi interfaces to stop working until they are manually restarted whereas the web interface works as exptected.

Motivation and Context

https://jira.slac.stanford.edu/browse/ECS-5126

How Has This Been Tested?

Interactively

Where Has This Been Documented?

Code will print out a message, but I did not update the serverStat readme description because I thought this would be too specific to mention.

[ZLLentz]

Ran as myself to confirm working:

zlentz@psbuild-rhel7-01:~/.../engineering_tools/scripts(serverStat -)$ ./serverStat drp-fake-machine off
The off and cycle serverStat commands are unavailable on DRP nodes. Do not use psipmi power off or psipmi power cycle directly on DRP nodes as this will disable the ipmi card. Instead, use the web interface as described on:

https://confluence.slac.stanford.edu/display/PSDMInternal/Debugging+DAQ#DebuggingDAQ-IPMI

[ZLLentz]

I'm 👍 with this, maybe @silkenelson has more specific requests for the verbiage.

[silkenelson]

Please hold this. I thought I had added a comment here yesterday with the exact verbiage I wanted which I assume I now have to remember what it was.

[KaushikMalapati]

@ZLLentz, could you approve this again? I just changed the exit message.

[ZLLentz]

I'm going to repost Silke's last comment as a suggestion because her messages seem to be getting buried- maybe as a result of how Github processes email replies?

I apparently can't English....can you change the beginning to:
serverStat $CMD is not supported for DRP nodes

Suggested change

	printf "serverStat $CMD is not supported on the DRP nodes as the underlying psipmi power off or psipmi power cycle commands will disable the ipmi card. Instead, use the web interface as described on:\n\nhttps://confluence.slac.stanford.edu/display/PSDMInternal/Debugging+DAQ#DebuggingDAQ-IPMI\n"

I think with her last request in I will re-approve and we can merge

[KaushikMalapati]

I completely missed this. How can I see this comment without your hyperlink?

[ZLLentz]

shellcheck is upset but hopefully your other PR handles the issues related to that, so let's merge this as-is!
