I'm searching for a method how I can recover a J-series router (J4350 and J6350) without removing the internal flash card from the router when the JUNOS becomes corrupt and does not boot any more. Is there a possibillity to (re-)install a JUNOS image with USB sticks or (t)ftp install method like it is possible on EX-series?
The only way I know is to take out the flash card, install the JUNOS install media with physdiskwrite (on Windows) to the flash card and then plug in the flash card into the router again.
The second "problem" I have is, if I install the install media image with physdiskwrite on a 2 GB flash card, the router can only use 1 GB flash, although the router recognizes that a 2 GB flash card is installed:
network@Econgas_nextlayer> show chassis hardware detail | match ad0 ad0 1918 MB SanDisk SDCFH-002G DOZ042610230849 Compact Flash
network@Econgas_nextlayer> show system storage | match ad0
Filesystem Size Used Avail Capacity Mounted on /dev/ad0s1a 742M 329M 405M 45% /
How can I tell the router to use the whole 2 GB flash space?
KB8017 is for JUNOS 8.5 and earlier, KB10800 is for the newer JUNOS releases. But this KB does not explain how I can install JUNOS on a blank flash card or on a flash card with a corrupt image that do not load?!
