Restoring a Backup Configuration
Before you restore a backup configuration for the Director group:
•
You must have a backup configuration file. You create the backup file with the request
system software configuration-backup command and save it on an external USB flash
drive.
•
If you need to reinstall the system software, perform that operation first (see
“Performing a QFabric Switch Recovery Installation on the Director Group” on page 410).
To connect and configure the Director group with a backup configuration:
1. Log in as root. If the software booted before you connected to the console port, you
might need to press the Enter key for the prompt to appear.
dg0 login: root
NOTE: The prompt is either dg0 login or dg1 login depending on the Director
device to which you connected your cable.
2. To use a previously saved backup configuration enter yes when prompted to specify
the backup file and then enter the path and filename of the backup configuration.
Specify a back up file? [y/n]: yes
Please specify the full path of the configuration backup file: path/filename
3. Confirm the restoration of the configuration from the backup. Ensure that the
information is accurate before proceeding.
