A few weeks ago monitoring alerted that a V245 server we use was down.
The issue was found to be a PDU to its cabinet which had tripped out.
However this only fed one PSU on the server – the other PSU was still receiving power from another PDU.
I found that the server would not come up/boot with only one PSU receiving power – it needed both PSUs receiving power to come up.
This of course rather scuppers any thoughts of avoiding single points of failure.
Has anyone any dieas why this may the case?
cheers
