Alcatel-Lucent OmniSwitch 9000 Series Getting Started Manual page 36

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
CMM Mode
Current CMM Slot
Running configuration
Certify/Restore Status
SYNCHRONIZATION STATUS
Flash Between CMMs
Running Configuration
NIs Reload On Takeover
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 is 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.
