[c-nsp] Nexus 7K NX-OS Upgrade

[Antonio Soares]

Thanks, I don't know if you noticed but somewhere in the thread the bug was
mentioned and it is resolved in 5.1.5 and later.

Bug CSCtn61286 - Boot variables are not set up correctly on Sup-2 after ISSU

So in my case, it should not give me problems (5.2.3a to 5.2.7).

But since I also need to upgrade the SUP1 RAM from 4G to 8G, I have no other
option than doing the traditional upgrade. It's the only way to just send
the box down 1 time:

- update the boot variables
- power off and upgrade the RAM
- power on

The install all script has another limitation: it won't let us to reboot
when we chose to do it. This is what happened to me last time:

+++++++++++++++++
Switch will be reloaded for disruptive upgrade.
Do you want to continue with the installation (y/n)?  y
 
Install is in progress, please wait.
 
(
.)
 
A few minutes later:
 
Finishing the upgrade, switch will reboot in 10 seconds.
+++++++++++++++++

I don't see how to upgrade the RAM and upgrade the NX-OS with the install
script in just one shot...

While doing some more testing this aft I also removed the sup from slot 5
and did a "disruptive" single sup ISSU upgrade from 5.1(5) to
5.2(7) on the slot 6 sup without issues.
