    Installing the Software on PTX10002-60C Routers

    This section explains how to upgrade the software, which includes both the host OS and the Junos OS. This upgrade requires that you use a VM host package—for example, a junos-vmhost-install-x.tgz .

    During a software upgrade, the alternate partition of the SSD is upgraded, which will become primary partition after a reboot. If there is a boot failure on the primary SSD, the device can boot using the snapshot available on the alternate SSD.

    Note: The PTX10002-60C device supports only the 64-bit version of Junos OS.

    Note: If you have important files in directories other than /config and /var, copy the files to a secure location before upgrading. The files under /config and /var (except /var/etc) are preserved after the upgrade.

    To upgrade the software, you can use the following methods:

    If the installation package resides locally on the host, execute the request vmhost software add <pathname><source> command.

    For example:

    user@host> request vmhost software add /var/tmp/junos-vmhost-install-ptx-x86-64-18.2R1.9.tgz

    If the Install Package resides remotely from the device, execute the request vmhost software add <pathname><source> command.

    For example:

    user@host> request vmhost software add ftp://ftpserver/directory/junos-vmhost-install-ptx-x86-64-18.2R1.9.tgz

    After the reboot has finished, verify that the new version of software has been properly installed by executing the show version command.

    user@host> show version
