Continuing the Upgrade: Transferring Customized Files to the Router
4-5
Table 4-1 shows which Bay Networks routers can read, write, and boot from the
different file format types.
When a BN running Router Software Version 8.10 or 9.00 reads a Flash card that
contains files written by a BN running Router Software Version 7.5x, and you
enter the
dinfo command at the Technician Interface prompt, the display indicates
that the volume is corrupted. If you request a directory of the volume’s contents
(using the
dir command), the display indicates that the contiguous free space is 0
(zero). You can, however, read and boot from the files.
You must convert the contents of a Flash card to a format compatible with the
router software currently running on a BN router. You do this by copying the files
to the router’s memory, reformatting the Flash card, and copying the files in
memory back to the Flash card. Follow these steps:
1. Insert the Flash card into the BN router.
2. Display the Flash card’s directory.
Select Commands➔Directory from the Router Files Manager window.
If the available free space and contiguous free space are equal, you cannot
compact the Flash card at this time; go to Step 3. Otherwise, go to Step 5.
