4 Maintaining configurations and firmware
This chapter contains procedures for maintaining switch configurations and maintaining firmware.
Maintaining configurations
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, HP recommends that you back up all important
configuration data for every switch on a host computer server for emergency reference.
The following sections contain procedures for basic switch configuration maintenance.
Displaying configuration settings
The switch configuration file contains four sections:
• The Boot Parameters section contains variables, such as the switch's name and IP address.
• The Licenses section lists the licenses that are active on the switch.
• The Chassis Configuration section contains configuration variables, such as diagnostic settings, fabric
configuration settings, and SNMP settings.
• The Configuration section contains licensed option configuration parameters.
To display configuration settings, connect to the switch, log in as admin, and issue the configShow
command. The configuration settings vary depending on switch model and configuration.
Backing up a configuration
If the configuration is lost or unintentional changes are made, keep a backup copy of the configuration
file (or a backup copy of both configuration files, one for each logical switch—if you are using a Core
Switch 2/64 or SAN Director 2/128 with two domains). The configuration file is what gets saved when
you issue the configUpload command. Keep individual backup files for all switches in the fabric. Do
not copy configurations from one switch to another.
The following information is not saved in a backup file:
• dnsconfig information
• Passwords
You must have a valid account on the FTP server where the backup file is stored.
You can specify the use of secure file copy (scp) during the procedure. For instructions on configuring the
use of scp by default, see ”Configuring secure file copy” on page 67.
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 as follows:
1. Verify that the FTP service is running on the host computer.
2. Connect to the switch and log in as admin.
3. Issue the configUpload command.
The command becomes interactive and you are prompted for the required information.
