[Beowulf] Beowulf Digest, Vol 162, Issue 17

Just to add to the excellent suggestions from others: have you compared
BIOS/
UEFI settings & versions across these nodes to ensure they're
identical?

Also verify that the CR2032 on the motherboard is in working order.
Usually this can be done with "sensors" or "ipmitool" which shows it
with a value near 3.3v If the motherboard battery fails the settings
can change, and not always to the default
BIOS values. Unfortunately Dell servers rarely expose this information
with either of those tools but other manufacturers often do.
