Upgrading The Controller Image - Brocade Communications Systems RFS6000 System Reference Manual

Upgrading the controller image

The controller ships with a factory installed firmware image with the full feature functionality
described in this System Reference Guide. However, Brocade periodically releases controller
firmware that includes enhancements or resolutions to known issues. Verify your current controller
firmware version with the latest version available from the Brocade Web site before determining if
your system requires an upgrade.
Auto installation
The controller auto install function can be configured manually or using a DHCP server. When
configuring auto installation using DHCP, the server requires the definition of a vendor class and
four sub-options under option 43 namely:
•
•
•
•
The individual features (config, cluster-config and image) can be enabled separately using the CLI,
SNMP or Web UI. If a feature is disabled, it is skipped when auto install is triggered.
For manual configuration (where the URLs for the configuration and image files are not supplied by
DHCP), the URLs can be specified using the CLI, SNMP or Applet. Use the CLI to define the
expected firmware image version. If the image version is not specified, the controller will derive it
from the header of the firmware image file.
Configuration files are tracked by their MD5 checksum. Configuration files are tracked by their
contents. If a file is renamed its contents remain the same and the file will not be reloaded.
The requested image file version (if any) is checked against the current version before any attempt
is made to load it. If the requested version is the same as the running version, no action is taken. If
the image file version (embedded in the file header) does not match the expected version, no
further action is taken. If the version has not been specified, the image file header is compared to
the local version. If they are the same, no action is taken.
NOTE
Once the system has been operating for ten minutes, Auto Install is disabled, though it may still be
reconfigured. This is to prevent the system from attempting to re-install each time a DHCP lease is
renewed.
Configuring Auto Install via the CLI
There are three compulsory and four optional configuration parameters.
The compulsory parameters are:
•
•
•
Optional (only for the static case):
