Active - Standby Sync using TMSH commands

Hi Mareeswaran, there is a good article on the subject on AskF5. Please see SOL7024 for details.

The concept of device clustering changed completely with the introduction of v11 to become more flexible and scalable.

The previous deployment was limited to 2 units only. Always make sure your units are synched with NTP:

watch -d "ntpq -p"

Sometimes a timestamp mismatch prevents a config sync. Failing SCCP communication may also impact the config sync operation on the previous H/W platforms, if I remember right.

Please keep in mind, that a "full_box_reboot" is required to restart the SCCP as well. Maybe some units (and SCCP) have a longer uptime than 497 days.

Thanks, Stephan
