Considerations for downgrading firmware

Message The FS8-18 (type 43) blade is not supported by the target firmware. Please use slotshow to find out
which slot it is in and remove it first.
Probable cause and recommended action
The firmware download operation was attempting to downgrade a system to Fabric OS v6.1.1_enc
or earlier with one or more Brocade FC8-18 AP blades (blade ID 43) in the system. Brocade
Encryption Blade FC8-18 AP blades are not supported on firmware v6.1.1 or earlier, so the
firmware download operation failed.
Use the slotShow command to display which slots the Brocade FC8-18 AP blades occupy. Physically
remove the blades from the chassis, or use the micro-switch to turn the blade off. Retry the
firmware download operation.
Firmware versions
These messages refer to differences between the current firmware and the firmware you are
applying to the switch.
Message Cannot upgrade directly to v6.3.0. Upgrade your switch to v6.2.0 first before upgrading to the
requested version.
Probable cause and recommended action
If the switch is running v6.1.0 or earlier, you are not allowed to upgrade directly to v6.3.0 because
of the “two-version” rule.
Upgrade your switch to Fabric OS version v6.2.0 before upgrading to v6.3.0
Message Non-disruptive firmwaredownload is not supported when downgrading to 6.1. Please use
firmwaredownload -s to download the 6.1 firmware.
Probable cause and recommended action
If the switch is running v6.2.0, you will not be allowed to downgrade directly to v6.1.x without
causing disruption to your fabric.
Downgrade using the firmwareDownload -s command. For more information on using this
command, refer to the Fabric OS Administrator’s Guide.
Message Firmwaredownload of blade application firmware failed. Reissue firmwareDownload to recover.
Probable cause and recommended action
The firmware download operation was attempting to upgrade the SAS image while the blade was
operational.
Retry the firmwaredownload command again.
Platform
These messages are switch features or fabric-wide settings that need to be removed or disabled
before downgrading the firmware.
