Hey there,
I was adding two shelves to one of my FAS8020s (cDOT, if that matters) recently and one IOM on each of the newly added shelves is missing in `storage show acp` or `acpadmin list_all` directly on the nodeshell.

I’ve done some research and found that usually a TO/GB helps in this situation, but I’m – of course – trying to avoid that.
So, any ideas how I can try to make those pesky IOMs respond on the ACP? I tried to disable and re-enable ACP, but that didn’t help (maybe I did it wrong, have never fully disabled ACP on a cDOT system), so any pointers are welcome.
Also, config advisor suggests to install missing shelf firmware, so I was wondering if it is safe to install the shelf firmware while an IOM is missing on the ACP?
Thanks,
