About the pre-upgrade check
The pre-upgrade check determines if the system is ready for an upgrade. The pre-upgrade check runs automatically when you start the upgrade. The pre-upgrade check runs at the beginning of an upgrade and checks for any potential problems that might result in an upgrade failure. If the pre-upgrade check fails, the upgrade cannot proceed. You must resolve the issues before you upgrade the cluster.
The following tests are performed during the pre-upgrade check:
System self test to verify the health of system and software services, such as network, MSDP, and NetBackup.
Version check to ensure that the upgrade path is supported and the current system can be upgraded to the target version.
The Docker daemon is configured correctly.
Hardware vendor package that is compliant with the appliance is present on the cluster.
Note:
Vendor package is also required for VMware-based deployments. Note that VMware-based deployments are not supported in production environment and can only be used for proof of concept or in demo environment.
Sufficient free space is available for the upgrade.
No other bootable devices are present that may interfere when restarting the nodes during the upgrade.
For scale-out media server deployments, the NetBackup primary server version is compatible with the media server version.
The administrator password does not expire within seven days.
All the cluster nodes are up and healthy with the same software version installed on all the nodes.
No add node, replace node, or restore jobs are running on the cluster nodes.
Starting with version 3.0, you can run a pre-upgrade check independently after you download an upgrade package from the Veritas website or when you upload an upgrade package from a local system.
To run a pre-upgrade check independently on an upgrade package:
- Use any one of the following options to log in using the user account that you created when you configured the cluster:
Use a user account with both Appliance Administrator and NetBackup Administrator role, or a user account with only an Appliance administrator role to log in to the NetBackup Flex Scale web interface
https://ManagementServerIPorFQDN/webuiwhere ManagementServerIPorFQDN is the public IP address or the FQDN that you specified for the NetBackup Flex Scale management server during the cluster configuration. In the left pane click Cluster Monitor > Infrastructure, and then click Cluster Dashboard.Use a user account with an Appliance Administrator role to log in to the NetBackup Flex Scale infrastructure management console
https://ManagementServerIPorFQDN:14161where ManagementServerIPorFQDN is the public IP address or the FQDN that you specified for the NetBackup Flex Scale management server and API gateway during the cluster configuration.
- In the left navigation click Settings, and then Software management.
- If not already done so, download the upgrade package from the Veritas website, or upload the upgrade package from a local system:
To download the upgrade package:
On the software management page click Software updates.
