We're going to upgrade the supervisor cards of the 2 Nexus 7000 by passing a SUP-1 to a SUP-2.
This upgrade will enable routing on the Nexus.
The maintenance works will begin at 00:00 (CEST) This tuesday October 21st.
Update(s):
Date: 2013-10-24 15:21:54 UTC All done, we're in 6.1. We 'll talk to Cisco
to find out why it crashed.
Date: 2013-10-24 13:53:19 UTC Go:
We're cutting all the ports on A.
Traffic will flow via B.
No downtime expected.
Date: 2013-10-24 13:52:17 UTC We're shutting down all ports on chassis A, which is in 6.2,
so that the traffic flows only via 6.1.
We will update A to move it onto 6.1 (hot or cold swap).
We will put get all ports back up and everything
should work as before the update.
We will then launch the instant update of B onto
version 6.2, and we'll see if it still crashes on the
2nd supervisor. If so, we will let Cisco fix the problem for us
however long it takes.

Date: 2013-10-22 06:25:31 UTC Following the maintenance, we have noticed an issue with the vlan management of some hosts (a twenties). Thereafter troubleshooting, it doesn't seem like the network is at the origin of the issue. There's actually a board effect due to the maintenance which has an impact on these hosts. We are carrying on the troubleshooting along with the VMware.
