How can switches that are in non-provisioned mode be transferred to Pre-provisioning mode

  • 1.  How can switches that are in non-provisioned mode be transferred to Pre-provisioning mode

    Posted 07-28-2023 06:34
    One of our customers has two switches in a virtual chassis at one of their locations
     
    EX4300-32F:
     
    fpc0:
    -------------------------------------------------- ------------------------
    Hostname: umk-swcore
    Model: ex4300-32f
    Junos: 20.2R3-S3.6
     
    fpc1:
    -------------------------------------------------- ------------------------
    Hostname: umk-swcore
    Model: ex4300-32f
    Junos: 20.2R3-S3.6
     
    It's time to upgrade. Since the switches are in active production, the user wants to do NSSU.
    But when he starts NSSU he gets a message
     
    me@430032F> request system software nonstop-upgrade /var/tmp/jinstall-ex-4300-21.4R3-S3.4-signed.tgz
    Chassis ISSU Check Done
    [Jul 27 12:33:54]:ISSU: Validating Image
    error: Pre-provisioning not configured
    error: ISSU Aborted!
    [Jul 27 12:33:55]:ISSU: Error
    Chassis ISSU Aborted
     
    As Pre-provisioning is a mandatory prerequisite for NSSU, and the switches are configured as non-provisioned, the user wants to switch them to Pre-provisioning mode. The question is: How can switches that are in non-provisioned mode be transferred to Pre-provisioning mode without having to configure the switches from scratch?
    Configuration of 4300 virtual chassis:

    set virtual-chassis no-split-detection

    set virtual-chassis member 0 mastership-priority 129

    Thanx in advance,
