[j-nsp] RE : T Series RE-1300 CompactFlash Card upgrade

[Rafael Rodriguez]

Thank you for pointing that out. My experience with upgrading the cf cards has only been on the J series - dd image on and your good to go.  I did not realize that the install-media for the  M, T, and MX is more of an "OS install/boot CD". We were having issues booting up the REs with the out-of-the-box sandisk (yep regular, non extreme) installed in the cf slot. RE would try to boot from cf and fail (obviously, noting installed on it) and then fail to boot off the hd for some reason. Boot order had cf, before hd. Removed cf from bootlist but re still tried to boot off of cf first. Anyways, going to try the following:

Zero out sandisk cf
Pop cf back into RE
Hopefully have it boot off hd
request system snapshot (copy 10.0 from hd onto cf)
Reboot off cf (should now have 10.0)
Perform standard upgrade process until we get to the desired code version

Will post my findings, thanks!

You don't dd the install-media code to the CF, you dd it on either the PCMCIA or USB Key (depends on the RE), then you boot from it and it will install a fresh JunOS on your CF/RE, formatting everything in the process. If that fails, it's either a bad install-media or a faulty CF.

I've tried this now on two REs with the same result.  On the CF we have (from install-media) 10.4R5.5.  Im kind of stumped with this one, don't know what I am doing wrong.  Any help is greatly appreciated.  Thanks.

Preparing the CF on a similar system but different kind of RE leads sometimes to trouble (CF is seen but the system can't load correctly). Install-media always solved that kind of situation. Of course, you lose everything on the HD and CF, it's formatted, so backup what you may need previously.
