Why 5.3.2 and not 5.3.3? 5.3.2 is an early deployment and 5.3.3 is the
extended maintenance release?

Yes.

If you unpack "asr9k-mini-px.pie-5.x.x" from the main tar from Cisco
and instal that, that will be your base.

You can erase the router and install from fresh though then you wont
have any space issues. You can ftp/tftp the full tar to "harddisk:/"
so you just turboboot the mini VM image "asr9k-mini-px.vm-5.x.x" and
install the rest from harddisk after boot (you need to fully re-store
the config and license files after this).

Note, IOS-XR will usually install to "disk0" so you can chuck files on
o "harddisk:" at your leisure. Also look at the output from "dir
disk0:" There shouldn't be any tar files in the root so check that if
you are low on space, also as others have said remove unused and
inactive packages.


Cheers,
James.
