Nexus 7000 Upgrade Notes [Step by Step]

In this article, we will describe the step needed to perform the Nexus 7000 Upgrade using the ISSU method:

Upgrade procedure summary:

Step-1: Take a backup of the current configuration

Step-2: Download the target images and verify their integrity via MD5.

Step-3: Upload the Software and Kickstart images to the Nexus 7000 Switch (active and standby SUP):

• bootflash: or  bootflash://sup-1/   (essentially the same location on supervisor engine 1)
• bootflash://sup-2/ This is the supervisor engine 2 bootflash

• Active SUP:

NEXUS_7000# copy tftp://192.168.1.1/n7000-s2-dk9.7.3.5.D1.1.bin bootflash:

NEXUS_7000# copy tftp://192.168.1.1/n7000-s2-kickstart.7.3.5.D1.1.bin bootflash:

• Standby SUP:

NEXUS_7000# copy tftp://192.168.1.1/n7000-s2-dk9.7.3.5.D1.1.bin bootflash://sup-2/

NEXUS_7000# copy tftp://192.168.1.1/n7000-s2-kickstart.7.3.5.D1.1.bin bootflash://sup-2/

• To check that image are uploaded correctly:

NEXUS_7000# dir bootflash://sup-1/

NEXUS_7000# dir bootflash://sup-2/

2/ INCOMPATIBLE CONFIGURATION CHECK, VERIFYING ISSU CAPABILITY, TESTING THE UPGRADE PROCESS:

NEXUS_7000# show incompatibility system n7000-s2-dk9.7.3.5.D1.1.bin

The show install all impact command will take a long time to complete as it simulates the upgrade process.

NEXUS_7000# show install all impact kickstart bootflash:n7000-s2-kickstart.7.3.5.D1.1.bin system bootflash:n7000-s2-dk9.7.3.5.D1.1.bin

3/ PERFORMING THE NEXUS ISSU UPGRADE:

Once the initial checks are complete, you’ll be promoted to confirm with a “y” (yes) to continue with the installation

NEXUS_7000# install all kickstart bootflash:n7000-s2-kickstart.7.3.5.D1.1.bin system bootflash:n7000-s2-dk9.7.3.5.D1.1.bin
