Upgrade HA Active/Passive array to latest version.

Good morning all,

I hope you're all well.

I'm looking for some advice on the most expeditious and least disruptive method to upgrade an HA array to the latest firmware version. It's a UTM SG330 setup in HA active/passive mode and the firmware version is 9.702-1.

The customer is highly risk averse and supports several hundreds of remote users via remote access vpn. It is essential that disruption is kept to a minimum. Multiple or lengthy outages need to be avoided if possible.

Does anyone know the most direct path from the current firmware to the latest version?
Would it be quicker to reimage/rebuild the array at the latest version and import the latest backup? Is it possible to import a backup from the current version to the latest version?

Thanks in advance,

Neil.

  • Hello ,

    Thank you for reaching out to the community. 

    When you upgrade an HA device, the process is as follows:

    1. The primary device (device A) upgrades the secondary device (device B).
    2. Device…

  • Thanks for your answers.

    I think the rebuild is the most likely option as the customer is unlikely to risk any lengthy outage or maintenance windows to complete a phased upgrade.

    Thanks for your help.

  • Re-imaging is a waste of time and completely unnecessary. The whole point of the HA is to "not disrupt" and it won't - the users won't even know, especially if you run it at say 2-4 am in the morning on a schedule. Simply let it download all the updates, hit upgrade to latest at this time and go to bed. Done.

  • I agree, but there's a potential fly in the ointment.  Attempting to get all of the needed Up2Dates loaded at one time will cause problems with a full / partition - probably a lockup.  Probably two groups would need to be downloaded separately.  This is most easily done at the command line as root.

    Don't forget to set 'Firmware Download Interval' to "Manual" before starting and to change it back when done.  If the Up2Dates below are already on your system, you can delete them once you're in /var/up2date/sys.

    Once you're at 9.705-3 or you've done something similar to the below to get you there, here's how to get to 9.711-5:

         cd /var/up2date/sys
         wget ftp-astaro-com.s3-eu-west-1.amazonaws.com/UTM/v9/up2date/u2d-sys-9.705003-705007.tgz.gpg
         wget ftp-astaro-com.s3-eu-west-1.amazonaws.com/UTM/v9/up2date/u2d-sys-9.705007-706009.tgz.gpg
         wget ftp-astaro-com.s3-eu-west-1.amazonaws.com/UTM/v9/up2date/u2d-sys-9.706009-707005.tgz.gpg
         wget ftp-astaro-com.s3-eu-west-1.amazonaws.com/UTM/v9/up2date/u2d-sys-9.707005-708006.tgz.gpg
         wget ftp-astaro-com.s3-eu-west-1.amazonaws.com/UTM/v9/up2date/u2d-sys-9.708006-709003.tgz.gpg
         wget ftp-astaro-com.s3-eu-west-1.amazonaws.com/UTM/v9/up2date/u2d-sys-9.709003-710001.tgz.gpg
         wget ftp-astaro-com.s3-eu-west-1.amazonaws.com/UTM/v9/up2date/u2d-sys-9.710001-711005.tgz.gpg
         /sbin/auisys.plx --showdesc

         Wait 10 minutes after the auisys command starts and then install in WebAdmin. You are now at 9.711-5.

    Personally, I would disconnect the Slave first and allow the Master to Up2Date overnight.  Then, re-image the Slave, power it down, reconnect it and power it up.  The Master will reconfigure the Slave and copy the logs to it.

    If you do go the way of re-imaging both Master and Slave, you can copy off the /var/log directory beforehand and then copy it back on with WinSCP.  Again, I would fully prepare one appliance as the Master and then reconnect the Slave and power it up.  The Master will reconfigure the Slave and copy the logs to it.

    Cheers - Bob

  • Thanks everyone for your input, very much appreciated.

    As mentioned, the customer is very risk averse and has several hundreds of remote workers connecting via the SG, so updates have been avoided for as long as possible, which is how we came to be in this position.

    As Bob mentioned, we cannot download all updates because the partition fills up.

    The agreed process is to break the array, reimage the secondary to the latest firmware version, apply a temporary licence and import the latest config. Once this has been satisfactorily tested, the primary will be brought up to the latest version by reimaging and the array will be rebuilt.

    The customer understands this will cause a network outage, but they can live with that since it will be planned and can be done in the wee small hours when all remote workers are sound asleep.

    Thanks for all your help.

    Neil.

  • That plan means you lose all logs and reporting, Neil.  You can use the WinSCP trick to copy /var/log off and then back on again.

    Cheers - Bob
