7220 HA DATA NOT SYNCRONIZING

Hi all

 

I am facing an issue with my controllers in HA any changes in one controller is not being duplicated to other ie: data not synchronizing .

 

Please suggest any remedy 

 

thanks in advance

Re: 7220 HA DATA NOT SYNCRONIZING

Are these in Master/Master Standby? Do you have database sync enabled?

 

#show database synchronize

If these are Master/Local, are the IPSEC tunnels formed between them?

 

(On Master)
#show switches

Don't forget that not all changes (such as VLAN's, DHCP, IP etc) are not sync'd between controllers.

Hi Zalion

 

Thanks for your reply, but tell me one change which i can perform and data will synchronize. 

 

(TEST1) #show database synchronize

Last synchronization time: Not synchronized since last reboot

Periodic synchronization is enabled and runs every 5 minutes
Synchronization doesn't include Captive Portal Custom data

Re: 7220 HA DATA NOT SYNCRONIZING

Is your deployment Master/Master Backup, as the show database sync is relevant. If you wish to complete a manual database sync then perform the following

 

#database synchronize

If you wish for this to happen automatically:

 

(Aruba620) #configure terminal
Enter Configuration commands, one per line. End with CNTL/Z

(Aruba620) (config) #database synchronize ?
captive-portal-custom   Include custom captive portal files
period                  Periodic synchronization with standby (Master-Master
                        Communication)

But again this is only for a Master/Master Backup deployment....

Please find the running config for both controllers, might be HA is not configured properly.

Re: 7220 HA DATA NOT SYNCRONIZING

I can't access the attachments at the moment, can you please provide the output of the following on each controller.

 

#show roleinfo
#show switches

Re: 7220 HA DATA NOT SYNCRONIZING

Both servers are masters, so they are islands and will not synchronize anything.

 

You have to configure the second controller as a local or a backup master for redundancy.  A local controller will allow you to have access points on both controllers at the same time.  A backup master will only allow you to use one controller and the second controller will backup the first.

Re: 7220 HA DATA NOT SYNCRONIZING

Am unsure whether you want Master - Master Backup or Master-Local design, but you have not configure either one.

 

For Master-Master Backup:

https://www.arubanetworks.com/techdocs/ArubaOS_63_Web_Help/Content/ArubaFrameStyles/VRRP/Redundancy_Parameters.htm

 

For Maste-Local there are multiple examples on this foro and on the Internet.

 

At the moment you have 2 independent devices.

Re: 7220 HA DATA NOT SYNCRONIZING

I agree both controller running on master mode but first of all i'm explain you the network scenario.

 

we have Total 538 AP but we have 500 ap license for one controller which means 500+ 500=1000 AP license for two controller.

so we planned 269 ap deploy on 1st controller and 269 ap deploy to 2nd

controller but we want when 1st or 2nd controller goes down so rest of the AP switch to active controller and only 38 AP goes down not for the 269.

Also we want all the data synchronize to each other

kinldy tell me both controller configured on which mode.?
