HP StorageWorks 2.128 SAN Director Switch - Manual (Page 76)

76 Maintaining configurations and firmware
If
fmsmode
is enabled in a configuration file, but is disabled on the switch, the
configdownload
command fails and displays an error message. This prevents undesirable conditions that could result from
enabling
fmsmode
on a switch that does not require it.
Downloading configurations across a fabric
To save time when configuring fabric parameters and software features, you can save a configuration file
from one switch and download it to other switches of the same model type, as shown in the following
procedure. Avoid downloading configuration files to different model switches, because that can cause the
switches to fail.
1. Configure one switch first.
2. Use the
configUpload
command to save the configuration information.
See ” Backing up a configuration ” on page 73.
3. Use the
configDownload
command to download the file onto each of the remaining switches.
See ” Restoring a configuration ” on page 74.
Printing hard copies of switch information
HP recommends that you print a hard copy of all key configuration data, including license key information
for every switch, and store it in a secure place for emergency reference. Print out the information from the
following commands, and store the printouts in a secure location:
• The
configShow
command displays configuration parameters and setup information, including
license information.
• The
ipAddrShow
command displays the IP address.
• The
licenseShow
command displays the license keys you have installed and provides better detail
than the license information from the
configShow
command.
Depending on the security procedures of your company, you might also want to keep a record of the user
levels and passwords (including any boot ROM passwords) for all switches in the fabric. Access to this
sensitive information should be limited.
Maintaining firmware
This section explains how to obtain and install firmware. Fabric OS 5.0.1x provides nondisruptive
firmware installation.
In most cases, you will be upgrading firmware; that is, installing a later firmware version than the one you
are currently running. However, some circumstances might require installing an earlier version; that is,
downgrading the firmware. The procedures in this section assume that you are upgrading firmware, but
they work for downgrading as well, provided the old and new firmware versions are compatible. Always
reference the latest release notes for updates that may exist regarding downgrades under particular
circumstances.
Using the CLI (or HP Advanced Web Tools), you can upgrade the firmware on one switch at a time. You
can also use the optionally licensed HP Fabric Manager software tool to upgrade firmware simultaneously
on multiple switches. For details on Fabric Manager and other licensed software tools, visit the HP web
site: http://h18006.www1.hp.com/storage/saninfrastructure/switches.html .
Obtaining and unzipping firmware
Firmware upgrades are available for customers with support service contracts and partners on the HP
Storage web site: http://welcome.hp.com/country/us/eng/prodserv/storage.html . For currently sold
switches:
1. Locate the Networked storage section under IT storage products and click Storage area networks.
The SAN Infrastructure page is displayed.
2. Click Fibre Channel Switches.
The Fibre Channel switches page is displayed.
3. Go to the B-Series Fabric-Enterprise Class section and select the appropriate switch.
The switch overview page is displayed.
