I have got problem in F5 BIG IP LTM ver 12.1.1
Changes Pending ,What should i do please advice me
check both devices are reachable from each other also check below link
It appears that device 02 is the most up to date, if you know there aren't changes on device 01, then you can sync to the group from 02. However, it's worth reviewing the config to ensure there isn't anything needed that will be overwritten.
That said, as device 02 is currently active it would certainly be safer to sync from 02 to the group. Just check the config on 01 and manually make any necessary changes to 02 before syncing
What are the configuration .i need to check ?
You can do a comparison of the /config/bigip.conf from each device.
Open it up in Notepad++ or similar and compare the differences.
If there is configuration on the standby unit that is not on the active one, verify if it's needed.
If not you can ignore it, if you do need it, add it manually to the active device.
How can i show the configuration (/config/bigip.conf)
DMZ01)(cfg-sync Changes Pending)(Standby)(/Common)(tmos)#
Syntax Error: unexpected argument "/config/bigip_base.conf"
check time and date on both boxes.check back to back connectivity and HA selfip reachability.
F5 BIG-IP having different times on the devices check NTP: System ›› Configuration : Device : NTP-(time.windows.com) how can test the ntp server does it work ?. if we want to set this time & synchronise then how it can be done? is it required down time?
no it will not require to reboot or downtime.NTP is recommended for this or you can manually set the time with the help of https://support.f5.com/csp/article/K3381 . let me know does it fix your issue or not.
If you're sure your active(self) device has the most recent configs in there then You may want to overwrite the configuration from 02 to 01. Sync may not work from 02 to 01 since there is a config conflict between the two appliances.
In Sync options: Enable sync device to group and select overwrite configuration. This should not break anything unless your standby device has the latest config than active device.
