Hi, I would try taking it down to minimum to post and see if you still have the issue. Page 106 [URL]
A R630 we have has been in continuous use for over 3 years since it was purchased new in October 2016 but had to be powered down last week owing to electrical power installation work being carried out in the server room. When it was powered back on, up popped a message about the BIOS battery being low or missing & to press F1 to continue. So I powered off and replaced the battery but now the system will hang a few seconds into the boot, wait for about 30 seconds before the screen goes blank and it reboots from cold with the 'Configuring memory...' message and the cycle repeats. It makes no difference whether I boot from local disk or a USB pen drive and the problem persists with different Linuxes and FreeBSD. I've reset the BIOS to defaults, checked the H330 RAID controller settings (we're using 4 disks in JBOD on this server) updated all the firmware (BIOS, LCC, iDRAC, onboard Broadcom gigabit NICs and the dual Intel X520 10 GB NIC PCie card and the mini-H330). UEFI hardware diagnostics all pass OK including the 256 GB of memory. On Linux, the issue occurs about 5 seconds into the boot with the console hanging after the ACPI probing while with FreeBSD, the hang occurs slightly later with a console message stating 'the first hard disk on the RAID controller is not certified'. Am I missing something? We've had no problems with this system until now and has been powered on continuously although rebooted for routine O/S & software upgrades 4 or 5 times.
R430 server hangs and then reboots during boot
