Just for anyone else who read this, the issue was a local execution

connection: local

this causes the system to SSH to itself and there is no tmsh on the ansible host. removing this line and then adding delegate_to: localhost when calling a BIG-IP module solved this issue. it allows the playbook to remote execute the code via SSH

After removing it and fixing a few code tweaks we were able to launch the code

#!/bin/bash
OLDIFS="$IFS"
IFS=$'\n'
disk=$(/bin/tmsh show sys sof status | awk '/.D[1-9]/{print substr($1,1,4)}' | head -n1)
maxvnumber=0

for vnumber in $(/bin/tmsh show sys sof status | grep complete)
do

vnumber=${vnumber:4:2}
vnumber=${vnumber// /}

if (( vnumber > maxvnumber )); then
maxvnumber=$vnumber
fi
done

volume=$disk$((maxvnumber + 3))
echo -n $volume
IFS="$OLDIFS"

Yes, I'm using admin account and pwd.
I can login directly to the F5 without any issues.

OK i think that might be the issue, Typically the Admin account is logged in via TMSH console when SSHing into the box. you would be running native TMSH at that point. when i was running the SSH connection was done as Root to run the script with TMSH then the admin account is used to execute modules. The command we use above to run the script will SSH direct to the box and execute.. if you are already in TMSH, TMSH as a command doesnt exist.

Admin when SSH == TMSH

Root when SSH == Bash with TMSH capabilities

Does this make sense?

  Yes, it makes sense.
  I tried used the exact same config and ran the playbook.
  It still doesn't seem to recognize the script.
  
  I'm also noticing the following error now:
  
  An exception occurred during task execution. To see the full traceback, use -vvv. The error was: TypeError: startswith first arg must be str or a tuple of str, not NoneType

    Sorry for the delay when i got back from Ansiblefest had family things come up.
    
    The error indicates that something in the code failed and returned either NONE or NULL type value and thats why u see the error.
    
    If you want we could try and do a zoom to take a look at your setup and see if we can resolve where the issue is. ill PM you my Info!
