JUNOS recovery internal flash J-series

‎07-19-2011 02:52 AM

Hello,

 

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?

 

Thanks in advance!

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?!
