  • 1.  WARNING: THIS DEVICE HAS BOOTED FROM THE BACKUP JUNOS IMAGE

    Posted 05-01-2024 13:22

    Hello,

    my SRX300 says that it boots from the backup partition:

    ***********************************************************************
    ** **
    ** WARNING: THIS DEVICE HAS BOOTED FROM THE BACKUP JUNOS IMAGE **
    ** **
    ** It is possible that the primary copy of JUNOS failed to boot up **
    ** properly, and so this device has booted from the backup copy. **
    ** **
    ** Please re-install JUNOS to recover the primary copy in case **
    ** it has been corrupted and if auto-snapshot feature is not **
    ** enabled. **
    ** **
    ***********************************************************************

    but when I issue the commands:

    - show system alarms
    No alarms currently active

    - show chassis alarms
    No alarms currently active

    I recall on the srx100, srx210 и srx240, the same command would render:

    • show chassis alarms
      2023-03-17 10:34:46 MSK Minor Host 0 Boot from backup root

    Is that the 'default' behavior for the SRX 300 ?

    That's surprising. I have a 340 which did raise a minor alarm about this not too long ago.  If you have auto-snapshot enabled, though, you wouldn't get an alarm.

    Hello,

    thanks for your reply. I'll enable auto-snapshot and see what happens...
