  • 1.  Warning messages after upgrading Junos on stand alone EX4550 & Backup partition Junos upgrade

    Posted 12 days ago
    Hi,

    Firstly, I have upgraded Junos on EX4550 switch  from Junos version 12.3R6 To 15.1R7-S6.3 successfully on primary partition.
    But after upgrade i see these warnings mentioned below, i use a stand alone switch without any virtual chassis member. so i wonder if these warnings can be ignored or do something to remove these warnings.

    warning: This chassis is operating in a non-master role as part of a virtual-chassis (VC) system.
    warning: Use of interactive commands should be limited to debugging and VC Port operations.
    warning: Full CLI access is provided by the Virtual Chassis Master (VC-M) chassis.
    warning: The VC-M can be identified through the show virtual-chassis status command executed at this console.
    warning: Please logout and log into the VC-M to use CLI.

    root@ex4550> show virtual-chassis mode
    fpc0:
    --------------------------------------------------------------------------
    Mixed Mode: Disabled


    root@ex4550> show virtual-chassis status

    Virtual Chassis ID: 0898.1f5b.b1f8
    Virtual Chassis Mode: Enabled
    Mstr Mixed Route Neighbor List
    Member ID Status Serial No Model prio Role Mode Mode ID Interface
    0 (FPC 0) Prsnt xxxxx ex4550-32f 128 Master* N VC

    Member ID for next new member: 1 (FPC 1)

    Secondly, after upgrading Junos on EX4550 switch  from Junos version 12.3R6 To 15.1R7-S6.3 on Primary partition, should i run following command "request system snapshot slice alternate" to copy Primary partition (15.1R7-S6.3) to Backup partition(12.3R6)?

    The reason why i am asking is when i tried to do  "request system reboot slice alternate" so that after rebooting from backup partition i planned to do junos upgrade same like i did on primary partition. But i got error "mgd: error: rename failed for /var/etc/pam.conf" and could not login to the switch and i have to do password recovery and also "rollback rescue" as the configuration was lost.

    So what is best practise to upgrade backup partition after primary partition is been upgraded. Is it "request system snapshot slice alternate" ? can you please help.

    Thankyou

    Regards

    Hi,

    Second question answer i got, its better to do "request system snapshot slice alternate" for copying Junos from Primary partition to backup partition.

    Hi Deekshap,

    Thankyou for the information. It seems after rebooting the switch the warnings are no longer visible when i login to cli.
