    Hi All,

     

    I am planning to upgrade SRX110HE and SRX210H remotely in our enterprise. It will be upgradation from JUNOS frm 12.1X44-D20.3 to 12.1X46-D65 on Branch SRXs. Need help with below queries:

    • As all SRX already in dual partioning , do I need to mention "PARTION" keyword in "reqest system software add \var\tmpfilename.tgz no-copy reboot" command?
    • Which partion will be having newer image of JUNOS? How can I make both partion having same JUNOS snapshot? I know " request system snapshot slice alternate" will help but still want expert inputs.
    • If  "reqest system software add \var\tmpfilename.tgz no-copy reboot" fails then how device will come up? 

    I am worried because It will be nearly impossible to go to datacenter if things go wrong?

     

    Thank You.

    ANS: NO, 12.1X44 will be already running with dual partition. You can use "show system snapshot media internal" to verify the same.

    Which partion will be having newer image of JUNOS?

    ANS: Newer version will go to Primary partition and Current 12.1XC44 will go to backup

    How can I make both partion having same JUNOS snapshot? I know " request system snapshot slice alternate" will help but still want expert inputs.

    ANS: You are right, run " request system snapshot slice alternate " after upgrade and reboot

    If "reqest system software add \var\tmpfilename.tgz no-copy reboot" fails then how device will come up?

    ANS: If upgrade fail device wont reboot. If there are any issues during reboot, device will try booting from backup partition which is 12.1X44

    Thanks a lot Suraj for your quick reply. It will really help me to proceed further and clearing my doubts.  Smiley Happy

     

    If "reqest system software add \var\tmpfilename.tgz no-copy reboot" fails then how device will come up?
    ANS: If upgrade fail device wont reboot. If there are any issues during reboot, device will try booting from backup partition which is 12.1X44

     

    Does it mean that if upgrade fails then it wont reboot and keep on running from snapshot stored in primary partion?

     

    Do you have any suggestion to prepare for worst case scenario if everything goes wrong?

     

    Sorry to bother you mate.
