Quickest Way to Fix
There is quick fix for preventing unexpected reboot.
If your Unity XT storage arrays are running any OE older than Unity OS 188.8.131.52.5.013 then you should upgrade OE.
If you don’t upgrade your Unity OS till now, please resign and allow other experts to hire for your position otherwise the instruction is so simple.
