5 Maintaining configurations
This chapter provides procedures for basic switch configuration maintenance.
Maintaining consistent configuration settings
It is important to maintain consistent configuration settings on all switches in the same fabric because
inconsistent parameters (such as inconsistent PID formats) can cause fabric segmentation. As part of
standard configuration maintenance procedures, it is recommended that you back up all important
configuration data for every switch on a host computer server for emergency reference.
NOTE: For information about AD-enabled switches using Fabric OS 5.2.0 or later, see ”Managing
administrative domains” on page 143.
Displaying configuration settings
There are two ways to view configuration settings for a switch in an HP StorageWorks fabric:
• Issue the configShow command (less information).
To display configuration settings using the CLI, connect to the switch, log in as admin, and enter the
configShow command at the command line. The configuration settings vary depending on switch
model and configuration.
• Issue the configUpload command to upload an ASCII text file from the switch or switch module.
Backing up a configuration
In case the configuration is lost or unintentional changes are made, keep a backup copy of the
configuration file. You should keep individual backup files for all switches in the fabric and avoid copying
configurations from one switch to another.
The following information is not saved in a backup:
• dnsconfig information
• passwords
If your setup supports anonymous users, and you log in as an anonymous user, password is still a
required field, even though its value may be ignored by the FTP service.
Before beginning, verify that you can reach the FTP server from the switch. Using a Telnet connection, save
a backup copy of the configuration file from a logical switch to a host computer.
To upload a configuration file:
1. Verify that the FTP service is running on the host computer.
2. Connect to the switch and log in as admin.
3. Enter the configUpload command. The command becomes interactive and you are prompted for the
required information.
