The user upgraded their PTX10004 router from 22.4R2-S2.4-EVO to 22.4R2-S2-J8.1-EVO via JSU package - junos-evo-install-ptx-x86-64-22.4R2-S2-J8.1-EVO.iso.
The user was using 'request system software' command with restart keyword, the system did not reboot and FPC cards did not reset either. After upgrade, they found RE shell command cli-pfe did not work, output message is "could not open user interface connection: management daemon not responding".
It is dependent on the JSU package, the customer needs to reboot system after install some packages, just like this case. And it is case by case subject to JSU package code modifications, the customer needs to do some tests before upgrade.
Based on the JTAC lab test:
Our engineer team had written the code in the outputs: “A reboot is required to start using the new software.”
Please upgrade JSU 8.1 package with the following two ways (keyword no-validate is optional):
request system software add /var/tmp/junos-evo-install-ptx-x86-64-22.4R2-S2-J8.1-EVO.iso no-validate reboot
OR
request system software add /var/tmp/junos-evo-install-ptx-x86-64-22.4R2-S2-J8.1-EVO.iso
And then, manually reboot the EVO system.
Below I have done the following two tests:
Test 1:
=========
{master}
labroot@jtac-ptx10004-scapa-r2003-re0-re0> request system software add /var/tmp/junos-evo-install-ptx-x86-64-22.4R2-S2-J8.1-EVO.iso no-validate reboot
Jul 29 12:47:47
Adding software images. This process can take several minutes. Please be patient...
Download and Validate in Progress
<<<<<<< it is working fine, no issue observed after system reboot.
Test 2:
