We made the changes requested of us in Part 2. However we are still experiencing the occasional ping/fail on one of the switches. We have not seen an loop detected. Interesting to have loop protection turned on and doesn’t hurt anything but the blade centers and flex10s do not seem to be the problem.

So where do we go now?! Another call into hp support and they have directed us to perform the following steps:

1. Re-seat all components in the switch that keeps paging us.
2. Enable syslog on all switches and see if they say anything.
3. Add a timezone offset to the ntp configuration.

Hopefully this will show us what is happening as we still do not have a resolution. Or is it time to start replacing hardware? Is the sfp unit in the switch bad? is the 10g module bad? is the switch bad? lots of questions and no real firm answers as to why we get woken up in the middle of the night yet all seems fine except for a quick down/up event.
