Hi!

 

I have tried the solution but it didn't worked for me. i get this now:

 

Sync Summary Status Sync Failed Summary A validation error occurred while syncing to a remote device Details Sync error on TVLF5-02.com: Load failed from TVLF5-01.com 01070734:3: Configuration error: Modify of node attribute is not permitted. Recommended action: Review the error message and determine corrective action on the device

 

any suggestions?

 

Thanks, Aviv

    Hi Aviv, I guess, the configuration is somehow inconsistent. As you mentioned, changes were applied to both units. A logical configuration change (nodes, pool members, virtual servers etc.) should be synchronized in "overwrite" sync mode. If changes were applied to VLANs and self IPs it might become more complicated as the object names have to match in your cluster and i.e. for floating self IPs (which will be synced a VLAN and a matching self IP have to exist on the peer device). I am wondering, if you can locally save the configuration on command line: tmsh save sys config tmsh save sys ucs backup_bigip_date.ucs Thanks, Stephan

    Hi! F5 support helped me. we deleted all vs &pools & nodes from the standby device and then sync worked perfect Thanks a lot, Aviv
