Nexus upgrade from 5.1(3) to 5.2(3a)

Hello everyone.

I am completely new with Nexus and I am going to upgrade two 7010 from release 5.1(3) to 5.2(3a) due to a BGP bug.

Just want to know if any of you have done a similar upgrade and if there is anything that I need to pay special attention?

Do I need to reinstall all the licenses?

I am starting to read documentation but any advice will be apreciated.

Thanks in advance.

Joao.

Nexus upgrade from 5.1(3) to 5.2(3a)

Hi Joao,

You need not reinstall licenses if you are using permanent license already. Please check the below command to verify the license file exist on the device,

Nexus#show license brief

Nexus#show license usage

For NX-OS upgradation, if you are using dual supervisor, please verify that both supervisor has same DRAM (by default it will ship with 4GB and it can be upgrade upto 8GB)

Do #show system resources will show you the memory installed in the active supervisor (Since you are running 5.1.3, you might be using 8GB memory)

Nexus# show system resources

Load average:   1 minute: 0.16   5 minutes: 0.23   15 minutes: 0.21

To check the memory capacity on standby supervisor, please check below,

Nexus# attach module <module number> (where the standby supervisor installed)

Nexus#(standby)# show system resources

The Cisco NX-OS software supports in-service software upgrades (ISSUs) on devices with dual supervisor modules. An ISSU can update the software images on your device without disrupting data traffic. Only control traffic is disrupted. If an ISSU will cause a disruption of data traffic, the Cisco NX-OS software warns you before proceeding so that you can stop the upgrade and reschedule it to a time that minimizes the impact on your network.

An ISSU updates the following images:

  • Kickstart image
  • System image
  • Supervisor module BIOS
  • Data module image
  • Data module BIOS
  • Connectivity management processor (CMP) image
  • CMP BIOS

Berfore upgrade:

  • Do #show install all impact <system | kickstart> <image name>  command checks against a given image and informs the user if the images are compatible for an upgrade or a downgrade
  • Ensure that you have enough space in the standby bootflash
  • Copy the kickstart and system images to the Active and standby supervisor module using a transfer protocol. You can use ftp:,tftp:, scp:

    

Use Nexus# intall all kickstart bootflash:n7000-s1-kickstart.5.2.3a.bin system n7000-s1-dk9.5.2.3a.bin

See the below document which explain about the upgradation procedure,

Please inform me if you need more detail
