    Hello guys,

     

    Any help would be greatly appriciated 🙂

     

    I am trying to install/boot the Junos on my SRX300 using USB. (Just for learning purpose)

     

    Let's sayI have tried to upgrade th Junos using the 'request system software add' method and it was unsuccessful. Now I can't get to the CLI. 

     

    If I want to install / boot the SRX from the USB, how do I do that? I copied the Junos image into pen drive and went to 'loader' prompt. 

     

    loader> install file :///junos-srxsme-15.1X49-D120.3-domestic.tgz
    Target device selected for installation: internal media
    cannot open package (error 22)

     

    But it does not work. 😞 

     

    Note - SRX currently running at junos-srxsme-15.1X49-D120.3-domestic.tgz. 

     

    Thanks

    I am trying to install Junos from USB via Boot loader. (See the first post)

     

    Because the previous upgrade was unsuccessful using the normal 'request system software add ' command. After the reboot SRX is unstable and unable to go to the CLI. Even If I go to the CLI it is too slow and 'Status alarm is amber'

     

    My alternate partition has the older Junos which is stable but I am also unablr to boot from the back up partition. (Not sure how to do it)

     

    My friend suggested to Install the Junos from USB via Boot  loader. But I am unable to do so.

     

    Thanks

    Hi mate,

     

    Thanks for getting back to me.

     

    This is the command I entered on the loader:

     

    loader> install file :///junos-srxsme-15.1X49-D120.3-domestic.tgz
    Target device selected for installation: internal media 
    cannot open package (error 22)

     

    But it doesn't install.

     

    Thanks
