I did it long ago on a m40 and i seem to remember creating the partitions myself and dd'ing over the files from a working disk. As in having both the new and old HD in a fbsd box and working from there. This assumes a working hard disk from the router that has yet to fail but is old as dirt. But what if the old hard disk was toast? What would be the proper way to get a working hard disk back into a juniper router by doing it yourself? Could you create the partitions and MBR, install it back into the router and then take a system snapshot? I am trying to think it through as a mental exercise and I feel I may be missing something. Any tips from people who have recently done this would be greatly apprecaited! thank you, matt > -Paul- > > _______________________________________________ > juniper-nsp mailing list [email protected] > https://puck.nether.net/mailman/listinfo/juniper-nsp > _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
