Manual synchronization between sites participating in GSLB

Important: After a GSLB configuration is synchronized, the configuration cannot be rolled back on any of the GSLB sites. Perform the synchronization only if you are sure that the synchronization process will not overwrite the configuration on the remote site. Site synchronization is undesirable when the local and remote sites have different configurations by design, and can lead to site outage. If some commands fail and some commands succeed, the successful commands cannot be rolled back.

To synchronize a GSLB configuration by using the CLI:

At the command prompt, type the following commands to synchronize GSLB sites and verify the configuration:

              sync gslb config [-preview | -forceSync  | -nowarn | -saveconfig] [-debug] show gslb syncStatus 
             

Example:

              sync gslb config [WARNING]: Syncing config may cause configuration loss on other site. Please confirm whether you want to sync-config (Y/N)? [N]:y Sync Time: Dec 9 2011 10:56:9 Retrieving local site info: ok Retrieving all participating gslb sites info: ok Gslb_site1[Master]: Getting Config: ok Gslb_site2[Slave]: Getting Config: ok Comparing config: ok Applying changes: ok Done 
             

To synchronize a GSLB configuration by using the GUI:

Navigate toTraffic Management>GSLB > Dashboard.
Click非盟to Synchronization GSLBand selectForceSyn.
InGSLB Site Name, select the GSLB sites that are to be synchronized with the master node configuration.

Previewing GSLB synchronization

By previewing the GSLB synchronization operation, you can see the differences between the master node and each slave node. If there are any discrepancies, you can troubleshoot before synchronizing the GSLB configuration.

To preview the GSLB synchronization output by using the CLI:

At the command prompt, type the following command:

sync gslb config -preview

To preview the GSLB synchronization output by using the GUI:

Navigate toConfiguration>Traffic Management>GSLB>Dashboard.
Click非盟to Synchronization GSLBand selectPreview.
ClickRun.
A progress window displays any discrepancies in the configuration.

Debugging the commands triggered during synchronization process

You can view the status (success or failure) of each command triggered during the synchronization process and troubleshoot accordingly.

To debug the GSLB synchronization commands by using the CLI:

At the command prompt, type the following command:

sync gslb config -debug

To debug the GSLB synchronization commands by using the GUI:

Navigate toConfiguration>Traffic Management>GSLB>Dashboard.
Click非盟to Synchronization GSLBand selectDebug.
ClickRun.
A progress window displays the status of each command triggered during synchronization.
