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

[Antonio Soares]

Hello group,

 

Anyone knows the difference between using the install all script or just
update the boot system flash command when upgrading NX-OS on a Nexus 7K ?

 

The question applies to a single supervisor setup.

 

The official documentation mentions the two ways of doing it:

 

- using the install all script:

 

http://www.cisco.com/en/US/docs/switches/datacenter/sw/5_x/nx-os/upgrade/gui
de/b_Cisco_Nexus_7000_Series_NX-OS_Software_Upgrade_and_Downgrade_Guide__Rel
ease_5.x_chapter_00.html#con_314241

 

- using the traditional procedure:

 

http://www.cisco.com/en/US/docs/switches/datacenter/sw/5_x/nx-os/upgrade/gui
de/b_Cisco_Nexus_7000_Series_NX-OS_Software_Upgrade_and_Downgrade_Guide__Rel
ease_5.x_chapter_00.html#task_39E26688E1204F8CAAE876450A575E73

 

I had a bad experience in the past with the install all script. I was doing
an upgrade to a 7010 with only 1 supervisor that was installed in slot 6.
The install all script has a problem, may a bug, it only correctly updates
the boot variables for slot 5:

 

boot kickstart bootflash:/n7000-s1-kickstart.5.2.3a.bin sup-1

boot system bootflash:/n7000-s1-dk9.5.2.3a.bin sup-1

boot kickstart bootflash:/n7000-s1-kickstart.5.1.3.bin sup-2

 

The install all script assumes that if there is only one supervisor, it
should be on slot 5. Above we can see that the boot system is missing for
sup-2.

 

In summary, is there any problem if I simply update the boot variables and
reload ? May I end up with the supervisor running the new NX-OS release and
the modules the old NX-OS release ?
