Proper upgrade path for 56128P

Hi,

 

This being my first post - bear with me...

 

I need to do an ISSU upgrade of two Nexus 56128P switches to 7.3(0)N1(1) for the GEM to support 16Gbps FC transceivers. I just need to have input on the upgrade path as I want to avoid possible issues.

 

Current version: 7.1(4)N1(1)
Target version: 7.3(0)N1(1)

 

According to the release notes for 7.3 I need 7.2(1) for the ISSU to be non-disruptive, so far so good. My question is that in the release notes for 7.2(1) it lists 7.1(1)N1(1)-7.1(3)N1(2) as current releases, not my 7.1(4). Is that just due to my release (4) being created after the release notes itself or am I missing something? Can I see somewhere that 7.2(1) is a viable ISSU from 7.1(4) on my way to 7.3?

 

Feel free to ask qestions if I am unclear :)

 

Kind regards,

Jonas

You are correct in your assumptions upgrading one switch at a time if all your devices are dual homed you should have little to no downtime. Also ISSU in the field almost never works and I usually upgrade on device at a time in the end.

I just figured that we cannot utilize the ISSU process as we're running L3 functionality. Do you have any input on how upgrading - distruptive - will affect traffic if I'm running two of them in a vPC pair? The configuration should allow for one to go off-grid, but then, I might miss something :)

Did you ever get an answer regarding the path from 7.1(4) to 7.2(1)? I have the same scenario trying to get from 7.1.4 to 7.3.0.

Hi,

 

Upgrade can be done directly:

Table 3 Supported Upgrade and Downgrade Paths for Cisco NX-OS Release 7.3(1)N1(1)
Current Cisco NX-OS Release
Upgrade to NX-OS Release 7.3(1)N1(1)
Downgrade from NX-OS Release 7.3(1)N1(1)

7.3(0)N1(1)
7.2(1)N1(1)1
7.1(4)N1(1)

Nondisruptive upgrade (ISSU)

Disruptive downgrade2

 

NOTE:

1.Possibility of disruptive upgrade if FC or FCoE is enabled and upgrade is from Cisco NX-OS release 7.2(1)N1(1) or earlier. See CSCuq94445 for more details.

Make sure you always read the upgrade guides and release notes of the target release before performing any upgrades:
