storage takeover

[weiliu]

When I used node show to check the storage, I found that the "uptime" of a node was 67 days, because the auto-giveback of this storage was on, which means that this storage was taken over, restarted and returned 67 days ago.
No alarm related to him is found in the EMERGENCY,ALERT,ERROR file currently stored
What can I do to find out what went wrong on the day of storage?

Hello,

You can get the event log from that day and check if there is any information about the reboot.

Hello Weiliu,

Gmox is right, you need to download the SP/BMC logs from your cluster and manually check the events logs
(IPMI).

Depending on your platform you will need to run different commands. Please check the below KBs

If there was a reboot, it will certainly be there.
It will also give clubs on the RCA root cause
