dump errors / system halting

[Gr-R]

Thanks for the logs.
I don't see any issue that can be causing the shutdown.
You do have small problem with ADS connection, but this is likely related to the time difference between the DSS and the ADS server, or domain admin account is not the real domain administrator but a user with admin rights.
Check over the UPS and be sure it is not shutting down the systems itself.

Hi thanks for checking the UPS is actually not currently "managing" system shutdowns so it can't be that.

do the logs reflect a "crash" i.e. a oldschool bluescreen dump or simply the system stopping, as i said i need to get to the bottom of this as its getting crazy

try changing the RAID controller and see if it still fails:

just to confirm you would like me to migrate 18tb of storage to other controllers to see if it helps ?

any ideal how to go about that without having an identical box to use to host the data while i migrate it ?
