Cisco Nexus 1000v VSM upgrade
1.Download the necessary files from VCE portal based on your target RCM
2.Verify all the prerequisites on Cisco documentation:
(here’s the example for version we are upgrading to 5.2(1)SV3(1.5a)
3.Make sure there is sufficient space on active and standby VSM:
Log into active VSM
check active VSM disk space:
check the standby VSM disk space
– If needed delete old files using ‘delete’ command (always leave the current VSM version files just in case for the restore)
– repeat the same for standby VSM:
4.Copy the files onto active VSM.
In order to transfer the files, log onto active VSM and run:
– copy those onto the standby VSM
5.Copy running configuration to startup configuration
6.Power off standby VSM and clone to template:
After that power on the standby VSM and wait until it comes back up.
7.Backup and pre-checks
Log onto active VSM.
Copy running configuration to startup configuration:
Looking above we can see that the impact state is non-disruptive, we can verify the current and new version as well as ESXi compatibility.
It’s crucial that ESX hosts are compatible at this stage as the VEMs are not upgraded yet.
8.Verify Cisco VSG is not present in configuration
9.Begin the install
This will show the pre-checks table again and will prompt if you would like to take a backup. Select N (if you select Y, the installer will quiet and the backups are to be taken manually via scp commands as done in step 7)
The installer will hang on “Switching over onto standby” : (SSH session may timeout here, it’s OK!)
At this point wait few minutes and log-in to VSM (which is the standby VSM which has now became the active VSM)
Once logged in run:
10. Post-Installation checks
Run show version command on both active and standby VSM:
This should return the target version in our case 5.2(1)SV3(1.5a)
Copy running configuration to startup configuration (IMPORTANT)
