Restoring a Configuration Database to a Network Element
Use this procedure to restore a configuration database to a network element.
The (S)FTP server must be set up and active. See Adding an FTP or SFTP Server for information about setting up an (S)FTP server.
PSM supports network element database restore for the following:
BTI7800 Series network elements
BTI7000 Series network elements
BTI800 Series network elements (FTP only)
BTI700 Series network elements (FTP only)
MX Series and PTX Series routers (FTP only)
QFX Series switches (FTP only)
To protect network and server resources, limits are placed on the number of restores that can be run concurrently. See Managing Task Status for more details.
For the BTI7000 Series network elements, PSM performs both the Load/Invoke and Commit phases. The NE cannot be viewed between the invoke and commit stages (to verify the data before committing the restore). To verify the data before restoring, use the proNX 900 to perform each of the individual operations.
For the MX Series and PTX Series routers and QFX Series switches, PSM downloads the configuration to the router as the candidate version. PSM does not perform the commit. You have to log in to the router CLI to perform the commit.
- Right-click a network element, and choose Backup
& Restore >NE DB Restore.
The NE DB Restore dialog is displayed.
- Select whether you want to restore
the database from Local or Remote storage.
The Local option is only available for selection if the NE supports local storage.
- If you choose Remote storage, select an active
FTP server and subdirectory from the pulldown menu and click Browse to navigate to and select the backup file from which
you want to restore the database.
You can only browse within the starting directory and its subdirectories. The starting directory is the directory you specified when adding the (S)FTP server.
The file you select appears in the Restore File field of the NE DB Restore dialog.
- Click OK.
Use the View >Server >Tasks command to monitor the progress of the database restore task. For some network elements, this might take 15 minutes or more to complete.
PSM-generated NE database backup related alarms are not automatically cleared once the problem has been resolved. You must clear PSM-generated NE database backup alarms manually. To manually clear a PSM-generated alarm, right click the alarm and choose Clear NMS Generated Alarm. Once cleared, you cannot restore an alarm.
If you are using inband management communications for PSM through a BTI7000 Series NE, then you will not receive a response from the NE indicating the successful completion of the database restore.
