Junos Upgrade Help needed

llllvllll

I am planning to upgrade my router with dual Routing-Engine.
My confussion :-

I was thinking about uploading jinstall file in the var/tmp location then install it one by one. That is Back-up RE first then make it master then the Other RE.
What i want to know was if there are seperate /var/tmp location for both RE's ? or a common location.

Example if i upload the file in /var/tmp location and loggin to Back-up RE and type request system upgrade add validate /var/tmp/name
will it fetch the file or Both RE's have different /var/tmp location ?

Secondly i want to know if i use request system snapshot for backup will it backup both RE's files (if they are running different or same Junos version).

Thanks in advance

Each RE will have its own hard drive and file system. You'll need to copy the file to /var/tmp on both routing-engines. Should be able to do something like file copy /var/tmp/junos-image re1:/var/tmp to copy from one RE to the other.

I believe the snapshot command defaults to do a snapshot for both routing-engines, and I think it has options to let you specify a particular RE you want to snapshot. I haven't tried a snapshot with two REs on different code, but my guess is it will work.
