File Systems; Naming Files: Rules And Conventions - Nortel Versalar 15000 Troubleshooting Manual

Managing and Troubleshooting the Versalar Switch Router 15000

File Systems

The Versalar 15000 uses an NVFS consisting of one or more flash memory cards.
Each flash memory card is an NVFS volume. The NVFS on the router reads and
writes to one or more memory cards.
Note: The NVFS automatically mounts and unmounts memory cards.
Flash memory cards are 8 or 16 MB. Each memory card provides system access to
the software image and configuration file during a cold start. (A cold start occurs
when you cycle the power on the router.)
The volume number is the number of the slot that hosts the memory card. For
example, a memory card on an SSP card in slot 9 is volume 9. Each SSP card can
have one memory card.

Naming Files: Rules and Conventions

The rules for naming files are:
• You must specify the volume location (slot number) of any file that you
reference or create.
• File names must start with an alphabetical character. The remaining characters
must be alphanumeric, and may also include the underscore (_) character and
the dot (.) character. Spaces are not allowed.
• File names can consist of 1 to 15 characters. We recommend a limit of 8
characters, however, to ensure that all operating systems can recognize the
names.
• File extensions are optional and must be preceded by a file name and a dot.
The combined total for the file name and file extension is 15 characters
(including the dot).
You should use the following conventions when naming files so that you can
easily distinguish files by type:
• Use the .exe file extension for router software images.
