Verifying firmware download in logical chassis cluster mode
Any node failure or principal node failover can cause the logical chassis firmware download to be
aborted. After the firmware download logical-chassis command is returned, you should verify that
the command has been completed successfully:
1. Run show firmwaredownloadstatus rbridge-idrbridge-id to verify that the nodes have completed
the installation and are in the "Ready for activation" state.
2. Run show version rbridge-idrbridge-id to verify that the nodes have the correct firmware.
If any nodes are not in the "Ready for activation" state or do not have the correct firmware installed,
you should issue another firmware download logical-chassis command to upgrade the failed
nodes before activating the new firmware.
If the logical chassis firmware download keeps failing on any of the nodes, you might need to log in
to the failed nodes and recover them. For instructions, refer to
on page 120.
Upgrading and downgrading firmware within a VCS Fabric
Use this procedure, illustrated by an example topology, to upgrade or downgrade firmware within a
VCS Fabric.
It is important to reduce the downtime incurred by planned software upgrades. This section describes
how to upgrade and downgrade Brocade Network OS firmware images efficiently and safely onto a
variety of platforms in a VCS Fabric.
ATTENTION
This procedure illustrates an upgrade to Network OS release 4.1.1. For the limitations and caveats
related to a specific Network OS release, refer to the Release Notes for that release.
Although it is necessary to reboot the switches after the installation, the following benefits are
achieved:
• An optimal upgrade cycle for the entire fabric cluster
• Minimal loss of traffic
• No loss of configuration status
This procedure is supported on the following Brocade platforms:
• VDX 6710
• VDX 6720-24 and VDX 6720-60
