[j-nsp] Update to 9.4R1.8 gone bad

Tommy,

I am aware of what this command does up to
the point where it changes something on the
compact flash which makes it bootable again.

I reckon it repartitions it and copies the
necessary files?

Until now, that command struck me as a
backup mechanism. I presume there's more
behind it.

Digging a bit further I stumbled across
https://www.juniper.net/techpubs/software/junos/junos94/swcmdref-basics-services/request-system-snapshot.html
Below "Options" the "partition" parameter is
listed. Wild guess: this is run automatically
when the CF is faulty? (still assuming that
it actually was the problem)

For the upgrade I went through what's des-
cribed at
http://www.juniper.net/techpubs/software/junos/junos94/swconfig-install/installing-the-software.html

At the bottom it tells me to 'request system snapshot'
but that looks like optional not mandatory
to me, at least when it comes to getting the
router back to an operational status.

For now, I will just remember that command
as magic knob which fixes things.

To avoid this happening in the future: is
there a best practice to upgrade the soft-
ware or does the documented procedure usu-
ally work?

Cheers,

	sven03
