Pinned topic IBM V3700v1 random reboot

‏2019-05-07T13:42:29Z |

Hello,

I got various 2072-24C that I am currently working with. All of them works just fine. I set up a new cluster, made pools, MDisks and volumes just fine. I have one of them however, where node 0 keeps rebooting randomly. Fans are going very slowly and suddenly they spin up to max for about 10 seconds and the node is rebooting. It is not a complete reboot, I just lose access to it for about a minute. I see no errors anywhere or any indication that something might be wrong with it.

I am running with 18 800GB SSD's FRU 00AK376 and the node has FRU 00RY382 running firmware 7.5.0.14 since I only have 4GB memory in them.

I started initialization of the drives but I think the node rebooted during the making of the MDisks. I see all 3 arrays being initialized and I see time remaining, the time is going down and percentage going up. However it is under half the drives where the green LED is actually blinking. I think it's about 1.5 IO group that isn't blinking, which makes no sense to me.

I do not have access to previous firmwares so I can't downgrade.

I can't find anything on google about random reboots or restarts. The green LED's on the controller turn off and it is only down for about a minute, so it can't be a complete reboot, but something is happening.

Does anyone have any ideas here? Something I can try that I haven't? I did a reinstall of the 7.5.0.14 firmware which did not help.

The node is the configuration node, but I do not care about the data on it just yet.

 

EDIT:

I just tried to connect through node 1 instead. That one goes straight to the service interface. I cannot get it to go to the GUI at all. In the service interface both controllers are listed as active with no errors.

    I cannot upgrade further given that I only have 4GB memory in it.

     

    I let it sit overnight and the next day it stopped doing this. I removed the system and set up a new cluster and it seems to be working fine now.

    First thing I would do is a system upgrade (7.8.1.9). Lot's of resolved APARs, and then go from there.
