    Posted 05-04-2017 05:18

    Experts,

     

    Due to power lost, 2200-C has been rebooted from backup partition, is there any way to fix this to start from primary partition?

     

    Message:

     

    WARNING: THIS DEVICE HAS BOOTED FROM THE BACKUP JUNOS IMAGE 

     

    Steps:

    request system snapshot media internal slice alternate
    request system reboot slice alternate media internal

     

    These did not work. Switch reboots from backup partition anyway Smiley Sad

     

    show system snapshot media internal

    Hi,

    Try to do only the first command:
    request system snapshot media internal slice alternate

    and then reboot : request system reboot .

    request system snapshot media internal slice alternate
    fpc0:
    --------------------------------------------------------------------------
    Formatting alternate root (/dev/da0s2a)...
    Copying '/dev/da0s1a' to '/dev/da0s2a' .. (this may take a few minutes)
    The following filesystems were archived: /
    
    {master:0}

    --------------------------------------------------------------------------
    Boot Media: internal (da0)
    Active Partition: da0s2a
    Backup Partition: da0s1a
    Currently booted from: active (da0s2a)
    
    Partitions information:

      s3d        369M   /var/tmp
      s3e        123M   /var
      s4d        62M    /config
    

    I think this did a trick. However my Juno os version is old [12.3R6.6] ..... I will try to upgrade to  12.3R12.4

    Formatting alternate root (/dev/da0s2a)...
    
    error: timeout waiting for response from fpc0
    

     

    but finally all is ok and both partition have same new Juno OS
