HA issue

[Michaelyang]

Hello,

I have two devices in HA status and they are as follows

Then for some reason I had to delete mgmt_IP, but after that, the HA status became strange as follows
And there is no way to do active/standby conversion...

I found that I had to let one device have mgmt_ip so that the state could be restored

What is the mechanism that causes these situations?
Any help is appreciate.

Hi,

Check, but maybe you set only management interface in Failover Unicast Configuration ? (Device Management ›› Devices › Failover Unicast Configuration )

Hi Lidev,

Thanks for your reply

I have set up two interfaces in the failover unicast configuration.(HA & mgmt)

Have you checked LTM logs for messages?

Hi CA_Valli,

Original : Michael_01 (standby/have mgmt_ip) / Michael_02 (active/none mgmt_ip)
17:41:17 -- delete Michael_01 mgmt_ip
17:42:58 -- Michael_02 want to change to standby

I checked it out and came up with the following log:
