Hey Guys good afternoon for Dr Daniel E Jacobs DMD - The server went down all of a sudden, Raid Controller in slot 4 operation failed, it doesn't want to boot at all, I tried already to unplug the server try to power drain it, waited for 2 minutes and plug it back online, issue persists is there something I can do on my end to try and fix this? Thanks

It’s Fixed. They had battery backup that would turn off and cause raid card to go offline. I bypassed the battery backup and will dispatch it to be replaced

The backups were missing full entry because Dr was swapping them weekly

# Fix Dell PowerEdge T440 RAID Controller Fault State Caused by UPS Battery Failure

## Problem

A Dell PowerEdge T440 server (Service Tag: CYDC1T2) failed to boot with the RAID controller reporting "Operation Failed" status. The system displayed UEFI error code UEFI0116 with the message "One or more boot drivers have reported issue(s)" and specifically showed the Avago MegaRAID SAS Controller in fault state with MFI Register State 0xF0FF0382. The server would not boot despite power drain attempts. All other components (iDRAC Settings and Broadcom Gigabit Ethernet drivers) showed healthy status.

## Resolution

1. Identify if the server is connected to a battery backup/UPS system
2. Check if the UPS battery is failing or causing power interruptions to the server
3. Bypass the failing battery backup temporarily by connecting the server directly to wall power
4. Schedule replacement of the faulty UPS unit
5. Verify that backup procedures are running properly, as UPS failures can interrupt scheduled backup operations

The RAID controller fault was caused by intermittent power loss from a failing UPS battery backup, which caused the RAID card to go offline and enter fault state.
