Alright, thanks – I’ll go for the reseating then since this seems to be the most reliable solution which also shouldn’t have any other impact to the system.

The other method that seems to work every time that will work for you is a cluster takeover and giveback.

I doubt rebooting the IOM will fix it.

The two methods I have used that seem to work every time:

1. Pull the IOM for 4 minutes and re-insert (more details earlier in thread) 2. Takeover/Giveback.

The short pull of the IOM was unreliable. Sometimes it worked, sometimes it did not and if it did not, it would usually cause other IOMS to misbehave for some reason.

There is also possibility to reboot IOM remotely, but you need to ask support how to do it.

since the filer is a few hundred kilometers away ATM I was hoping for a remote fix ☺ System is MPHA of course and I verified that with Config Advisor as well as on the CLI, so that shouldn’t be a problem.

Does it make sense to open a Case to make them aware of the fact? Could that also be a firmware issue on the IOMs or ACP that might be fixed by applying a new firmware? I’m not sure how firmware updates are applied to the IOMs – is that happening through the SAS cables or is ACP necessary for that? My idea was to start a firmware update on the shelves to see if that fixes the issue, since a firmware update also reboots the IOMs one at a time – but if ACP connection is necessary for the FW update to complete I’m out of luck here and will have to dispatch remote hands.

I’ve seen this issues on numerous installs now, including brand new systems. This is something that we should not have to be doing all the time. There has to be something else going on here.

Make sure your Multipath HA is working.

go to shelf 23 and disconnect the B IOM from the backplane (no need to fully remove, just electrical disconnect) go to shelf 15 and disconnect the B IOM

WAIT AT LEAST 4 MINUTES!!!

Insert them back in to the shelves.

Re-check after 15-20 minutes. That should do it. If there are still some missing, pull and wait at least 4 minutes. Make sure to only do one side (a or b) at a time!

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,
