Resetting NetBackup host attributes
In certain scenarios, you may need to clean up or reset host attributes: For example, you have downgraded the host.
In such cases, you need to reset host ID to host name mapping information, communication status and so on for successful communication.
You must reset the host attributes of the downgraded host if you want the primary server to communicate with the host in an insecure mode.
Resetting host attributes resets host ID to host name mapping information, communication status and so on. It does not reset the host ID, host name, or security certificates of the host.
After you reset the host attributes, the connection status (is secure flag) is set to insecure state. At the time of the next host communication, the connection status is updated appropriately.
If you have inadvertently used the Reset Host Attributes option, you can undo the changes by restarting the bpcd service. Else the host attributes are automatically updated with the appropriate values after 24 hours.
See Add or Remove Host Mappings dialog box.
NetBackup 8.1 primary server can communicate securely with all 8.1 hosts. However, it communicates insecurely with 8.0 and earlier hosts.
In certain scenarios, you may need to downgrade a NetBackup client from 8.1 version to 8.0 or earlier. After the downgrade, the primary server cannot communicate with the client, because the communication status for the client is still set to secure mode. The communication status is not automatically updated to insecure mode after the downgrade.
Use one of the following options to reset a host:
To reset a host using the NetBackup Administration Console
- Expand Security Management > Host Management.
- On the Hosts tab, in the details pane, right-click the host that you have downgraded and which you want to reset, and click Reset Host Attributes.
Note:
To resume insecure communication with downgraded hosts, ensure that the Enable insecure communication with 8.0 and earlier hosts option on the Security Management > Global Security Settings > Secure Communication tab is selected.
To reset host attributes using the command-line interface
- Run the following command to authenticate your web services login:
bpnbat -login -loginType WEB
