This document describes how to troubleshoot a Cisco Firewall Services Module (FWSM) that displays the
File or directory already in use error when you attempt to save a configuration with the write memory
command in multiple−context mode.

The FWSM has a 128−MB Compact Flash memory card that stores the operating system, configurations, and
other data. This Flash memory is partitioned into six different partitions. Each is used for a different purpose
as outlined here:

Maintenance image − This is similar to ROM Monitor Mode (ROMMON) in Cisco IOS

®

. It allows

for password recovery as well as image recovery if partitions 4 or 5 become corrupt.

1. 

Network configuration for maintenance image

2. 

Crash dump

3. 

flash:/   Images (Operating System (OS), Adaptive Security Device Manager (ASDM), system startup
configuration)

4. 

Alternate boot image

5. 

disk:/   Security context configurations, Rivest−Shamir−Addleman (RSA) keys, arbitrary files

6. 

In Step 3 of the Solution section, you format partition number 6, so the FWSM IOS image is not affected.
Regardless, you should resave all configurations after a format.

This error is observed when you save the configuration in a specific FWSM context.
