The FEX is not recognised.

We checked the optical and fibre links and tested a spare FEX.

I rebooted one of the 2 Nexus. It may be a side effect of the upgrade to 7.1.1. this evening (http://status.ovh.net/?do=details&id=10277).

It definitely seems to be a side effect of the upgrade to 7.1.1. The FEXs are randomly disconnecting.

After a power-cycle reload, the FEXs are back.
I'll wait until all the FEXs are up before reloading the second N5.

The FEXs are up but the system is still a bit overloaded. We need to use MTS buffer n5# sh internal system mts buffers
MTS buffers in use = 234
