update ca -> need reboot ?

I have replace internal CA certificate on NSA6600 HA pair.

After done machine needs reboot:

Status: Ready. Restart of the firewalls is required for changes to take effect. Click here for the staged reboot of firewalls.

Is it correct ?

Other unit like NSA 3600 and TZ500 with this update no needs reboot.

  • @Alberto,

    That does sound correct. Usually, a reboot is required for such a change.

    I open a ticket to check : Support Case 43627022

    because I have this question:

    How many failover if I reboot primary ?


    primary active - need reboot

    secondary standby

    reboot primary

    service on standby

    secondary active

    secondary now needs reboot ?

  • AlbertoAlberto Enthusiast ✭✭

    and why no reboot of other my sonicwall 3600 Tz 500 ?

    Is it for SSL VPN (only on 6600) ?

  • Since this message is showing up on the unit due to a certificate change, I think when you click on restart the secondary firewall should restart first and once it is back up, the failover should take place, and then the primary should restart.

    If you do not have preemption for HA, the secondary should stay active.

    I am not entirely sure, why this message only showed up for NSA 6600 and not for others. I have seen that message for the following scenarios:

    1) When the connection settings are changed from DPI to SPI or vice versa

    2) If Local flow collector is enabled

    3) Any hardware related changes made on the diag page

    4) Certificate changes that are used for HTTPS management or SSLVPN.

    Was there anything additional done on the NSA 6600?
