HA, slave failed

Richard Priest1

Hi,

We have a pair of SG650 currently on 9.506-2 and have attempted to update the code by updating the slave 1st, unfortunately this failed and has left the slave in an unusable state, initially it never passed the syncing stage, even after being left for a few days, after a power cycle it now doesn't respond to connection attempts.

I don't have much experience with Sophos UTM, but wanted to check that the following is a reasonable process to being the HA back up

power down slave, & disconnect all interfaces.

Power up & factory reset.

Configure as a HA slave device

Connect configured HA interface

Wait for sync to complete

reconnect all other interfaces.

Are there any gotcha's to look out for when performing this work? Can I do the initial config via CLI / console rather than the web GUI?

Cheers

Rich

    Hello Richard,

    Thank you for contacting the Sophos Community!

    Yes, the steps should be fine, I would just if possible to maybe try to re-image and update to the latest firmware if possible and also upgrade the Master. 

    Make sure also the two UTMs are directly connected via the HA link.

    Not possible to do it via the CLI, only via the GUI.

    Regards,

    many thanks emmosophos,

    I was hoping to bring it up to a working condition and then attempt the upgrade again on the slave. If I re-imaged the appliance to the latest version will it still sync as a slave to the master?

    Cheers
