Once in a time, a system administrator does a task which requires shut down of a LPAR. If a partition is about to switch off after some other task (for instance after a weekly backup) watching SRC codes, might be hopeless action.
Let me show a simple tool which does this ‘monkey job’.
I built a simple program which run on a different Lpar, and retrieve status of a LPAR from a HMC. When a partition become inactive, the program trigger a message to QSYSOPR, and perform any other action (for instance send a text message if possible).
This solution brings multiple benefits for a system administrator
- save time of a skilled personnel
- no monkey job
- it reacts automatically when a LPAR is off
- the tool can be used for other automation tasks
What do you need to run it?
- ssh keys with IBM i and a HMC which talks to the monitored LPAR
- some software which will notify a system administrator once a triggered messaged appears in QSYSOPR
How does it really work?
- the program query a HMC for status of monitoring LPAR by command lssyscfg in 60 seconds loops.
- if status is other than ‘Running’ it sends a message to QSYSOPR and ends the program.
Here is a simplified flowchart
