Managing application instances
You can manage your application instances from the System topology page of the Flex Appliance Console. To access your existing instances, click on the box on the home page or the icon in the left-side navigation bar, then navigate to the Application instances section.
Under Application instances, you can perform the following tasks:
Create a new instance.
Select an existing instance to:
Relocate it to another node if you have a multi-node appliance.
Stop or start it.
When you start an instance, Flex Appliance automatically determines which node to start it on for optimal load balancing. Therefore, it may not start on the same node that it was located on when it was stopped. If you want the instance to run on a specific node, you can relocate it after it starts.
Use thedrop-down to delete it.
Use thedrop-down to resize the storage.
Use thedrop-down to upgrade it.
Click on an existing instance to perform the following tasks:
You can also perform the following tasks outside of the Flex Appliance Console:
View live performance metrics of all of the instances on your appliance from the Flex Appliance Shell. See Viewing instance performance metrics.
Run NetBackup commands on a NetBackup master or media server instance from an SSH session.
Set environment variables on NetBackup 8.2 or later master server instances. See Setting environment variables on NetBackup instances.
Modify or disable the
nbdeployutilutility may adversely affect performance of NetBackup applications instances on a Veritas 5150 Appliance. If you do not need this feature or if you determine that it causes performance issues due to high CPU usage, you can modify the configuration or disable it as follows:
Log in to the master server instance and create the following nbdeployutil configuration file if it is not present:
Refer to the topic "Scheduling capacity licensing reports" in the NetBackup Administrator's Guide, Volume II for the procedure to use custom values for the capacity licensing report.
Flex Appliance does not support adding local directories or manually editing most files on application instances. If you create a local directory or manually edit a file and the instance is relocated or stopped for any reason, the changes are not maintained when the instance restarts.
However, if you must store a small amount of critical data on an instance, you can store it in the
/mnt/nblogs directory. Note that this directory has 250GB of storage space that cannot be resized. If you use too much storage space, the instance may be affected.
