How do I boot to previous firmware with Putty?

Rick Leslie

Hi All,

 

I 'upgraded' to firmware version 17 MR2 from 17 MR1.

 

Since the 'upgrade' I cannot access the web UI - I get a blank page with "Internal Server Error" in the top right corner in response to login submission.

 

I do not have easy access to connect a terminal cable but I can get access through Putty.

 

Is there a way to remove the MR2 or boot to MR1 using a connection with Putty?

 

Thanks

    Hi,

    Navigate to the option 5 (Device Management) > Option 2 (Show Firmware (s))

    You will see tow firmware available as shown below.

    Device Management

    1. Reset to Factory Defaults
    2. Show Firmware(s)
    3. Advanced Shell
    4. Flush Device Reports
    0. Exit

    Select Menu Number [0-4]: 2


    Firmware 1: SFOS 17.5.7 MR-7
    Firmware 2: SFOS 17.5.8 MR-8
    Current Firmware: Firmware 2
    In my case I had current firmware 17.5.8 MR8 so I had to run : rebootfw -f 1 and firewall rebooted with the firmware version 17.5.7 MR-7.

    SFVUNL_VM01_SFOS 17.5.8 MR-8# rebootfw -f 1

    Firewall rebooted with 17.5.7 MR-7

    Firmware 1: SFOS 17.5.7 MR-7
    Firmware 2: SFOS 17.5.8 MR-8
    Current Firmware: Firmware 1

     Thanks,

    Yeah, i have been doing that, except:

     

    Firmware 1 = 17.5.0 GA

    Firmware 2= 17.5.8 MR-8

    When i run the rebootfw -f 2, it times out with the "Broken pipe" after a while.

    Is it a HA?

    Yes, HA was disabled abruptly during the firmware upgrade, one unit did it ok, the secondary did not. And now the only way to reach the secondary is to ssh from the main unit via the Port3/DMZ IP address, and try run these commands that dont seem to be going through.  The firmware shows up on the secondary unit as Firmware 2: 17.5.8 MR-8, but rebootfw -f 2 wont run.
