The upgrade process attempts to download the latest plug-ins from SORT, which are used to determine if the appliance nodes are healthy and ready for upgrade. If the plug-ins are downloaded successfully, these are used to perform the pre-upgrade tests. If the download fails, the upgrade process checks if the latest plug-ins are already downloaded to the appliance node. If the plug-ins are already downloaded, these are used for the pre-upgrade tests; else the plug-ins that are included in the upgrade package are used to perform the pre-upgrade tests.
The GUI supports the following operations:
Check SORT for the availability of major upgrades, and patches. The option shows the details of packages available on SORT.
You can download available major upgrades, and patches from SORT.
The GUI displays the download package progress.
You can upload major upgrades, patches, and EEBs from your local systems.
The GUI displays the details of downloaded and installed major upgrades, patches, and EEBs.
You can delete major upgrades, and patches which are downloaded in the system through the GUI.
You can delete downloaded EEBs which are not installed on the system.
You can install major upgrades, patches, and EEBs only when all nodes are healthy.
You can rollback EEBs from the system only when all the nodes are healthy.
Depending on the EEB, you might need to ensure that there are no jobs running before you install or roll back the EEB.
If a node goes down during an upgrade, rollback will be triggered automatically. But if the nodes remains down, the rollback will fail and you must contact Veritas Support to resolve the issue.
The GUI disables other operations when installation or rollback operations are in progress.
The GUI displays the progress for operations like installation of major upgrades, patches, EEBs, and rollback of EEBs.
