[cisco-voip] MCS Series Boot Looping?

[Ben Amick]

Huh. That makes very little sense, but I guess it could be the cause. I'll have to try it after next time I need to reboot. We have KVM dongles on the back of all of our servers, and since they're old MCS units they have no other way to monitor boot time.

If you haven't already, try booting without any keyboard or mouse plugged in. Or at least nothing using a ps/2-to-USB converter or splitter or kvm box.

I found some issue in our HP equivalent (swonly) servers. Always had to do with that.

Not to mention a ps/2-to-USB converter sending a brand new be7k into a nose dive.

So I have the curious issue with my MCS series servers - but only the ones running CUCM 9.1 (originally installed with 8.5)
It seems every time I completely power them off and back on again, they boot up, boot to the linux shell, start kicking off the services, and once about half of the services are up, it boot loops and starts all over again.

The strange part is this only happens 2-3 times, and then its back to being solid gold. Had TAC analyze the system after the last time and they found no faults on anything, so I have no idea what happened.

Anyone else have any idea?
