Description

Similar to T295691 and T295690.

All management routers are running Junos 20 except mr1-codfw and mr1-esams that are running 18.

Management switches are on 17/18.

The current Junos recommended version for SRX300 and EX4300 is 21, so those 4 should be upgraded to reduce version spread.

@ayounsi the mentioned : "All management routers are running Junos 20 except mr1-codfw and mr1-esams that are running 18." and "The current Junos recommended version for SRX300 and EX4300 is 21" do you want for us to keep all at version 20 or update the listed once in the table to version 21?

Only those 2 from 18 to 21.
20 is recent enough.

Thanks

I was having the issue below upgrading mr1 to version 21

Validating against /config/rescue.conf.gz
/config/rescue.conf.gz:61:(21) syntax error at 'rfc-complaint'
  [edit system phone-home]
    'rfc-complaint;'
      syntax error
Validation failed
ERROR: Current configuration not compatible with /altroot/cf/packages/install-tmp/junos-21.2R3-S2.9
ERROR: Configuration validation failed with /altroot/cf/packages/install-tmp/junos-21.2R3-S2.9d

what i did to fix it was to run the command below and after run again the request software add command

request system configuration rescue save

After reboot it took 13:33 minutes for the router to come back online

papaul@mr1-codfw> show version

@ayounsi @cmooney i am having space issue on msw1-codfw which is preventing me to copy the Junos image to /var/tmp. request system storage cleanup didn't help. I took a look at what is using a lot of space (see output below) and show system storage /var/tmp is just at 9%

This issue was the file was copied first to /tmp before /var/tmp according to @ayounsi so copy the file first to local laptop and use scp to copy the file to /var/tmp
