    Hi,

    Without documentation, I recommend you open a support case with F5 level 4 " how-to ", because I am almost sure that these events are in var/log/ltm, but it's better if support confirms it if you can´t perform a failover.

    and the other question, the answer is Yes, Big-IQ is based on TMOS, and the OS is similar to Big-IP that runs TMOS inside too, you can try this command without any wrong behavior tmsh show /cm failover-status.

Hi,

If you don´t have a Qkview when the failover occurred, unfortunately, isn´t possible to review the causes of the failover.

Additional you can go deep in failover following this link

https://support.f5.com/csp/article/K95002127

To generate a Qkview in the case that failover ocurre :

 

  • Log in to the command line.
  • To run the qkview utility, type the following command: qkview
  • The output file name displays when the command has completed.
  • Collect the output file from the /var/tmp/ directory by copying the file to an external host using a utility such as ftp or scp.
