We have a 4 node cluster consisting of two AFF8080 HA Pairs, running 8.3.2P10. Two of the nodes are deliberately configured with only test/dev volumes because we need to shut those nodes down temporarily for about an hour to move them to a new rack.
I want to be sure this temporary shutdown is done cleanly and doesn't cause issues. Here are the steps I have taken or will take before shutdown:
- Moved Epsilon to the nodes that are staying up.
- Moved cluster ring functions to the nodes that are staying up.
- Will quiesce SVM root volume protection snapmirror jobs for test/dev SVMs.
- Will pause VSC backup jobs that point to test/dev volumes.
- Will issue the halt command with -inhibit-takeover and -skip-lif-migration-before-shutdown both set to true
Are there any other items I should consider to ensure a smooth shutdown? In particular I'm wondering if I should do anything else with the root volume protection snapmirror jobs. The root volumes for the test/dev SVMs (and their copies) are currently on the nodes that are staying up. Not sure if that will be an issue.
Would love to hear any feedback or suggestions!
