Running junos_install_os will successfully install the Junos Base OS Software Suite but its does not upgrade the Juniper Host Software in Juniper's QFX Series switches.
Juniper's Advanced JTAC Agent specified that this might create issues in the performance of the switch and it could be responsible for some of the problem we were having.
Juniper EX4200 USB Software Upgrade I had to add a Juniper EX4200 switch to a stack today which already had 8 switches in it. There are a few criteria which Juniper specify for adding a new switch to a stack. Upgrade and Backup JunOS Image of Juniper SRX Device. In this example I am using Juniper SRX 300 to backup and upgrade firmware of the device using command-line. I will also show how to do the upgrades in SRX cluster. Backup JunOS Image of Juniper SRX device. To create a backup to USB type the following command in operational mode.

Normally, if I'd perform the upgrade by hand I will use the command
request system software add reboot no-validate force-host /var/tmp/jinstall.......
But I need this to be perform by the Ansible playbook that will provision new racks
Is there anyway to make the junos_install_os upgrade the host software as well?
Thanks in advance and best regards,

I would like to upgrade firmware on both of my srx240 junipers in HA mode. Unfortunately both of them are quoted as EOL and have no active support warranty. I'm not able to buy new support warranty for them. Download links for older firmware releases are not available. As far as I know I should not upgrade between two Junos OS that are more than three releases of each other. So where can I get download links for all firmware releases (steps) between 10.0R3.10 and the newest one? Please help
