Performing a software upgrade
You use the fss-upgrade.sh script to perform the software upgrade
steps. The command syntax is as
follows:
[root@fss-deployer ~]# /root/bin/fss-upgrade.sh
Usage: /root/bin/fss-upgrade.sh configure <config-file> - Reads config file and configures accordingly.
./bin/fss-upgrade.sh discover - Discovers cluster.
./bin/fss-upgrade.sh upgrade - Upgrades FSS application.
./bin/fss-upgrade.sh status - Prints status of cluster and FSS Chart information.
./bin/fss-upgrade.sh clean - Cleans temporary files.
./bin/fss-upgrade.sh [help | -h] - Prints usage.This script updates the entire Fabric Services System application using the new Helm charts.
-
Update the configuration.
In the following example, the input configuration file is customer-input.json.
[root@fss-deployer ~]# /root/bin/fss-upgrade.sh configure customer-input.json Timesync service is running on 192.168.59.195 Time difference is 0 seconds Timesync service is running on 192.168.59.129 Time difference is 0 seconds Timesync service is running on 192.168.59.127 Time difference is 0 seconds Timesync service is running on 192.168.59.201 Time difference is 0 seconds Timesync service is running on 192.168.59.183 Time difference is 0 seconds Timesync service is running on 192.168.59.190 Time difference is 0 seconds Maximum time difference between nodes 0 seconds Successfully configured. Please run /root/bin/fss-upgrade.sh upgradeNote: Do not execute the fss-upgrade.sh upgrade command as indicated in the output. Continue with Step 2. -
Discover the cluster.

Verify that the upgrade is successful.

Restore previously added software catalog images.
The upgrade procedure replaces the software catalog. Changes that you made to the software catalog are lost after the upgrade. If you previously added new SR Linus images to the software catalog, you need to modify the software catalog and then upload the SR Linux images. For instructions, see Adding a new software catalog in the Fabric Services System User Guide. You need to complete this step before you can access the Fabric Services System to make any change.
