Nexus 5548 Software Upgrade

[Mokhalil82]

Hi Guys

I need to carry out a software on some Nexus 5548 switches from version 5.1(3)N2(1a) to version 6.0(2)N1(1).

I have carried out upgrades on cisco catalyst switches but never on Nexus. How difficult is it and what process can I follow.

Any help will be much appreciated

Thankyou

Mokhalil82,

First, you need to review the release notes for 6.0 (2) and make sure you have no significant impact to the network. The upgrade on a Nexus is pretty simple depending on your configuration. Do you have FEX switches connected to you N5548? I assume you have the system, kickstart files already downloaded and a backup config has been taken. 

The following commands is one option I have used to upgrade the N5548 and also execute some basic clean up steps after the upgrade is complete.

switch# copy tftp://192.168.x.x/n5000-uk9-kickstart.6.0.2.N1.1.bin bootflash:n5000-uk9-kickstart.6.0.2.N1.1.bin

switch# copy tftp://192.168.x.x/n5000-uk9.6.0.2.N1.1.bin bootflash:n5000-uk9.6.0.2.N1.1.bin

switch# dir bootflash:/// [view downloaded files in bootflash]

switch# install all kickstart bootflash:///n5000-uk9-kickstart.6.0.2.N1.1.bin system bootflash:///n5000-uk9.6.0.2.N1.1.bin

You will be prompted to confirm the upgrade, the switch will also preform prechecks and will advise know if the UG will be disruptive or non-disruptive.

switch# delete bootflash:///n5000-uk9-kickstart.5.1.3.n2.1a.bin [delete old files once complete upgrade]

Thanks for your reply. There are some fex's connected. will this make a diference

Ive never done any upgrade on the nexus so im told it needs upgrading to version 6.0(2)N1(1)

So I assume under that software version I will have a system image and a kickstart image. Is there any other extra precautions you recommend, I have the backup of the configs already
