Uploading the upgrade file and performing an upgrade precheck
Upload the upgrade file to the cluster and run an upgrade pre-check. The upgrade precheck determines if the system is ready for an upgrade. The pre-check does not require a scheduled downtime.
Run the precheck at least 10 days prior to the upgrade so that you can identify any configuration issues that might prevent the upgrade from proceeding smoothly. The results will allow you to assess whether the upgrade is feasible and give you enough time to resolve any problems, ensuring that the upgrade can proceed on the planned date.
Run the precheck again a day before the upgrade to catch any last-minute changes or issues that might have arisen since the initial check to reduce the chances of upgrade failure and ensure minimal downtime.
If the precheck fails, the upgrade cannot proceed. You must resolve the issues before you upgrade the cluster.
To upload the upgrade file and run the precheck:
- Sign in to the NetBackup Flex Scale web UI.
- Click Cluster Management > Cluster settings > Software management.
- On the Software management page click Software update.
- To upload the upgrade file that you had downloaded earlier, click Upload file. Select the file and then click Upload. After uploading the package, it is displayed under Downloaded package files.
Note:
Ensure that you do not navigate away or refresh the page while the upload operation is in progress.
- To start the upgrade precheck, under Downloaded package files for the file, from the Actions menu (vertical ellipsis) click Start pre-check.
When prompted for confirmation click Start pre-check. A success or failure notification is displayed on the top of the page. To view detailed status, click View details.
- If the precheck is successful continue to perform the preupgrade tasks. See Performing pre-upgrade tasks.
If the precheck fails, review the failures displayed in the GUI. You can also collect logs for further analysis. See Collecting logs for an upgrade precheck failure.
