Troubleshooting: Preparing appliance for upgrade
To initialize upgrade process, you need to execute prepare-for-update klish command. While executing it there can be following errors:
Verifying Initial Configuration failure
This error occurs if you execute prepare-for-update command again without rollback previous execution. Once the command is executed, the virtual appliance is powered-off and ceased to be usable. If you want to use the same virtual appliance, use the command rollback-update to make it healthy.
Checking available disk space failure
This happens if the required space is not available on the data disk. To resolve it, you can delete the old log gather if exists. Still if you face this issue, expand the disk using add-disk klish command.
Verifying Resiliency Manager health check failure
This failure occurs if the Resiliency Manager or other Resiliency Managers in the resiliency domain in case of multiple Resiliency Managers are not in healthy state. Make sure all the Resiliency Managers are connected and healthy before executing prepare-for-update command. It can also fail if the core service is not running on any of the Resiliency Managers in the domain.
Powering off other Resiliency Managers, if any failure
In case of multi-Resiliency Manager setup, prepare-for-update request is broadcasted to all the Resiliency Managers in the resiliency domain. On execution, all the Resiliency Managers are powered off. If any virtual appliance fails to power-off, then it could happen because of one of the following reasons:
You must not have executed the prepare-for-update on the appliance. If you have, then firstly execute the rollback-update to delete the saved configuration.
Check required space is available as defined in point Checking available disk space. To confirm the error, you can re-execute prepare-for-update from the node which was failed to power-off, but before this make sure all the Resiliency Managers are in connected state and if any Resiliency Manager got powered-off in last execution then power it on and execute rollback-update to make it healthy.
