UCS 2.0 Upgrade Order

It seems they took the most important section out of the 2.0 upgrade guides: the required order of steps.  It is now buried in the guide.

The following order is used when upgrading from 1.4 to 2.0:

1. Update adapters, CIMC, IOMs
2. Activate adapters
3. Activate CIMC
4. Activate UCSM
5. Activate IOMs - set startup only
6. Activate subordinate FI
7. Manually failover FIs if there is a concern for loss of control plane traffic (Optional in lab environments)
8. Activate primary FI
9. Host firmware package

VMware has the CLI pretty locked down on ESX version 4.1 and later (as compared to the commands that were available in 4.0).  The following can be used to view the ARP table in later versions:
