I don't think you can partition HDD from scratch with "request system
snapshot partition".
In fact, you cannot run "request system snapshot partition" even if HDD has
JUNOS 8.5 on it and flash has <8.5.
Temporarily pulling a flash out and using a PCMCIA card to repartition and
reinstall the same version of JUNOS on
HDD only will get you an operational HDD. Then you can put the flash back
and make sure the boot sequence is right
so that router boots from flash. Then you can run "request system snapshot
partition" and you're done.

Hello,
its not that hard to do. In general you do the following:
If the flash is still working the RE should boot up fine saying that it
is creating an emergency /var partition in ram.
You should be able to login.
Issue the following command:
request system snapshot partition
This will partition the hdd and copy JunOS over to it.
Basically this should be all you need to do. However it might be
required to reinstall JunOS via a jinstall package. YMMV.

Hello All,
We had an M20 hard drive die on our routing engine. We ordered a used
IBM hard drive and the Juniper seems to be detecting it. The problem
we are having,however, is figuring out how to get JunOS back onto the
hard drive.
I was reading the "JunOS Cookbook" and there's a section for making
and using an emergency boot disk. I tried that out, but it's not
working.
Has anyone else had this problem or has ideas about how to get the M20
back up and running from a crashed HD?
Thanks for the help!
