Upgrading the SSD Firmware on Routing Engines with VM Host Support

 

Starting in Junos OS Release 17.2R1, you can upgrade the solid-state drive (SSD) firmware on MX Series routers with the RE-S-X6-64G and RE-MX2K-X8-64G Routing Engines, on QFX10002-60C switches with the RE-QFX10002-60C Routing Engines, and PTX10002-60C routers with the RE-PTX10002-60C Routing Engines. A set of two SSDs, disk1 and disk2 , is available for normal functioning of the Routing Engine. This topic shows how to perform the upgrade.

Note

You must upgrade SSD firmware only under the direction of a Juniper Networks support representative.

Note

On QFX10002-60C switches, you can upgrade firmware only for the FPGA and BIOS, not the SSD.

Before you begin upgrading the firmware, check the current firmware version of the SSD.

user@host> show system firmware

If the value of Current version is less than the value of Available version, then you can use the following procedure for the SSD firmware upgrade.

To upgrade SSD firmware:

  1. Copy the jfirmware package to the device.

    If the file has been obtained from JTAC, use FTP or SCP to load the firmware file on the device. Save the file in the /var/tmp directory.

    user@host> request system software add ftp://ftp.juniper.net/private/system/jfirmware-17.1R2-signed.tgz

  2. Upgrade the SSD disk1 firmware. Note

    In releases before Junos OS Release 18.3R1, you must upgrade the SSD on a master Routing Engine only. For upgrading firmware on the backup Routing Engine, switch mastership by using the following command and then log in to the backup Routing Engine, which is now the new master Routing Engine:.

    user@host> request chassis routing-engine master switch

    Starting in Junos OS Release 18.3R1, you can upgrade the SSD firmware on the master and backup Routing Engines.

    To initiate the upgrade, use the following command:

    user@host> request system firmware upgrade re ssd disk1

    Monitor the upgrade status by using the show system firmware command.

    user@host> show system firmware
    user@host> show system firmware

    After a successful upgrade, confirm that the current version and available version of the SSD firmware are identical.

  3. Upgrade SSD Disk2 firmware.

    To initiate the upgrade, use the following command:

    user@host> request system firmware upgrade re ssd disk2

    Monitor the upgrade status by using the show system firmware command.

    user@host> show system firmware
    user@host> show system firmware

    After a successful upgrade, confirm that the current version and available version of the SSD firmware are identical.
