Managing Router Files

5-27

Partitioning the ﬁle system divides it into two independent volumes of equal size.

You can store default boot images and conﬁguration ﬁles on each volume for

redundancy. Then, if the router is unable to boot from the primary ﬁle system, it

automatically attempts to boot from the secondary (or backup) ﬁle system.

For example, suppose the NVFS for your Access Node resides on a 4-MB SIMM.

Partitioning the ﬁle system creates two 2-MB volumes. The volumes function

independently, and you reference them with unique slot and volume identiﬁers.

You could then copy the ﬁles from the primary volume to the secondary volume.

Creating a Partition

To partition the NVFS on an AN or ASN, follow these steps:

1. In the Router Files Manager window, select the volume you want to

partition. Make sure the value for

Contiguous free space is no more than

half of the volume’s total size.

To create volumes of equal size, the existing ﬁle system cannot be more than

half of the total media size. If the ﬁle system is too large, you might want to

do one or more of the following so that you will be able to create a partition:

— Format the media, as described in the previous section.

— Delete some ﬁles, as described in “Deleting a File” earlier in this chapter.

— Compact the ﬁles, as described in “Compacting File Space on a Memory

Card or Flash SIMM” earlier in this chapter.

2. If you want to partition the ﬁle system on an ASN, make sure that the

ﬂash memory card is not write-protected. (By default, we ship memory

cards unprotected.)

See Installing and Maintaining ASN Routers and BNX Platforms for

information on setting the Read/Write switch on the ﬂash memory card.

3. Select Commands➔Create Partition

A window appears prompting you to conﬁrm your decision to partition the

media (Figure 5-15).

Note: You can partition ﬁle systems on 4-MB media only.
