The following items need to be addressed before downloading the specified
firmware:
Downgrade is not allowed because there are more than 2 FX8-24 blades plugged
in to the chassis. The limit after downgrade is 2. Please plug out the extra
blades and rerun the command
Firmwaredownload command failed.
The messages in this section are displayed if an exception case is encountered during firmware
downgrade. The following example shows feature-related messages that you may see if you were
downgrading from v6.4.0 to v6.3.0:
Downgrade is not allowed because there are ports configured on FX8-24 as VEX.
Please use "portcfgvexport CLI" to remove the VEX configuration.
Downgrade is not allowed because a range of ports not supported by the target
firmware are assigned to Logical Switches instead of Default Switch. Please
use "lscfg --restore_to_default FID" to move all vacant ports to the default.
Downgrade is not allowed because there are ports configued in CSCTL mode.
Please use "portcfgqos CLI" to disable the CSCTL mode
Downgrade is not allowed because dynamic area mode is enabled on default
switch, Please use "configure" CLI to turn this mode off
Downgrade is not allowed because zoning configuration has overlapping
(enhanced) TI zones in one or more contexts. Please use "zone --delete
zone_name" command to delete overlapping TI Zones before proceeding.
Downgrade is not allowed because either 1) One of the peer switch is
configured to use third party issued certificates, or 2) Certificate files
exist. Please remove or set the configurationto Brocade and delete certificate
files using "seccertutil delete -fcapall" before downgrading.
DSCP Marking for 7800/FC8-24 required firmware version v6.4.0 or higher.
Please remove the DSCP marking using the "portCfg fcipcircuit<ve-port> modify"
command before downgrading.
IPv6 for 7800/FX8-24 requires firmware version v6.4.0 or higher. Please remove
any FCIP circuits using IPv6 addresses using the "portCfg fcipcircuit
<ve-port> delete" command before downgrading firmware.
Advanced compression modes (moderate, aggressive) for FCIP tunnels on FX8-24
requires firmware version v6.4.0 or higher. Please switch to standard
compression using the "portCfg fciptunnel <ve-port> modify" command before
downgrading.
