March 2005 Files and Directories 39
How can I tell which directory the switch is currently
using?
When you first boot the switch, the /flash/working directory is
used; this allows you to save your initial configuration changes
to the boot.cfg file. However, subsequent boots may result in
your switch running from the /flash/certified directory. There-
fore, verifying the current running directory is a key step any
time you are configuring or monitoring the switch.
View the current directory by entering the show running-
directory command. For example:
-> show running-directory
CONFIGURATION STATUS
Running CMM : PRIMARY,
CMM Mode : DUAL CMMs,
Current CMM Slot : A,
Running configuration : WORKING,
Certify/Restore Status : CERTIFY NEEDED
SYNCHRONIZATION STATUS
Flash Between CMMs : NOT SYNCHRONIZED,
Running Configuration : SYNCHRONIZED,
NIs Reload On Takeover : ALL NIs
In this example, the switch is using the /flash/working direc-
tory.
Can I save changes to the Certified directory?
No. The /flash/certified directory is intended to store only
tested, reliable configuration and image files. Configuration
changes must be saved to the boot.cfg file in the
/flash/working directory. Once those changes have been road-
tested, the contents of the /flash/working directory can be
copied to the /flash/certified directory via the copy working
certified command.
What happens when the switch boots?
During the boot process, the switch compares the contents of
the /flash/working and /flash/certified directories. Based on
this comparison, the switch determines which directory to use
as its running software.
Working and Certified Are Identical
If the software in the /flash/working and /flash/certified
directories are completely identical, the switch considers the
software in both directories to be equally reliable. In this case,
the switch will run from the /flash/working directory.
When the switch is running from the /flash/working directory
software, configuration changes can be saved via the
write memory command.
