||Unregistered Cisco.com users cannot access the links provided in this document.|
||Access the Software Download Center by using this URL: |
||Navigate to the download site for your system. |
You see links to the download images for your switch.
||Choose and download the Cisco Nexus 1000V zip file and extract the kickstart and system software files to a server.|
|| Ensure that the required space is available for the image file(s) to be copied by entering the dir bootflash: command. |
We recommend that you have the kickstart and system image files for at least one previous release of the Cisco Nexus 1000V software on the system to use if the new image files do not load successfully.
|| Verify that there is space available on the standby VSM by entering the dir bootflash://sup-standby/ command .|
||Delete any unnecessary files to make space available if you need more space on the standby VSM. |
||If you plan to install the images from the bootflash:, copy the Cisco Nexus 1000V kickstart and system images or the ISO image to the active VSM by using a transfer protocol. You can use ftp:, tftp:, scp:, or sftp:. The examples in this procedure copies a kickstart and system image using scp:. |
||When you download an image file, change to your FTP environment IP address or DNS name and the path where the files are located.|
- switch# copy scp://filepath/kickstart_filename bootflash:kickstart_filename
Copy the ISO image.
- switch# copy scp://filepath/system_filename bootflash:system_filename
Copy kickstart and system images.
||switch# show install all impact kickstart bootflash:kickstart_filename system bootflash:system_filename |
Verify the ISSU upgrade for the kickstart and system images or the ISO image. The example in this procedure shows the kickstart and system images.
||Read the release notes for the related image file. See the Cisco Nexus 1000V Release Notes.|
||Determine if the Cisco Virtual Security Gateway (Cisco VSG) is configured in the deployment by using the show vnm-pa status command . |
If an output displaying a successful installation is displayed as in the example, the Cisco VSG is configured in the deployment. You must follow the upgrade procedure in the Cisco Virtual Security Gateway and Cisco Virtual Network Management Center Installation and Upgrade Guide. If an output displaying that the policy agent has not installed is displayed, continue to Step 13.
|| Save the running configuration to the startup configuration by using the copy running-config startup-config command.|
||Save the running configuration on the bootflash and externally. |
You can also run a VSM backup. See the “Configuring VSM Backup and Recovery” chapter of the Cisco Nexus 1000V System Management Configuration Guide.
- Save the running configuration on the bootflash by using the copy running-config bootflash:run-cfg-backup command.
- Save the running configuration externally by using the copy running-config scp://external_backup_location command.
|| Perform the upgrade on the active VSM using the ISO or kickstart and system images by using the install all kickstart bootflash:kickstart_filename system bootflash:system_filename command. The example in this procedure shows the kickstart and system images.|
||Continue with the installation by pressing Y. |
If you press N, the installation exits gracefully.
As part of the upgrade process, the standby VSM is reloaded with new images. Once it becomes the HA standby again, the upgrade process initiates a switchover. The upgrade then continues from the new active VSM.
||After the installation operation completes, log in and verify that the switch is running the required software version by using the switch# show version command |
|| Copy the running configuration to the startup configuration to adjust the startup-config size by using the switch# copy running-config startup-config command|
||Display the log for the last installation by entering the following commands.|
- switch# show install all status
- switch# attach module_name
- switch# show install all status
