About NetBackup Flex Scale upgrades and EEBs
NetBackup Flex Scale supports software version upgrades. The upgrade operation is supported using both the GUI and RESTful APIs.
Open a web browser and type the following URL in the address bar to sign in to the NetBackup Flex Scale infrastructure management UI:
https://ManagementServerIPorFQDN:14161
If you are using IPv6 addresses, use the following URL syntax:
https://[ManagementServerIP]:14161
Here, ManagementServerIPorFQDN is the public IP address, the FQDN, or the short host name that you specified for the NetBackup Flex Scale management server and API gateway during the cluster configuration.
Note:
If you access the NetBackup Flex Scale infrastructure management UI by using the short host name from a node, set the DNS settings (name server, domain name, and search domain) or ensure that the entry for mapping the short host name to an IP address exists in the hosts file of the node.
You can find the RESTful APIs at https://ManagementServerIPorFQDN:14161/swagger/infra/v1.0/
If you are using IPv6 addresses, use the following URL syntax:
https://[ManagementServerIP]:14161/swagger/infra/v1.0/
The NetBackup Flex Scale upgrade consists of several steps. These steps and the overall upgrade progress can be seen in the GUI. In case the upgrade fails at a step from where automatic rollback is possible, NetBackup Flex Scale completes the rollback automatically. The progress and status for rollback can also be seen on the GUI.
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.
You can upload major upgrades, patches, and EEBs from your local systems.
The GUI displays the download package progress.
The GUI displays the details of downloaded and installed major upgrades, patches, and EEBs.
You can install major upgrades and patches when all nodes are healthy.
You can install and roll back EEBs from the system if all the nodes are reachable.
Note:
Depending on the EEB, you might need to ensure that there are no jobs running before you install or roll back the EEB.
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.
Considerations about the upgrade workflow:
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 upgrade or rollback operations are in progress.
Any operation that changes the configuration is not allowed during an upgrade.
Note:
If disaster recovery is configured, make sure that you install the EEBs and patches on the secondary site.
