HP AE370A - Brocade 4Gb SAN Switch 4/12 Administrator's Manual page 170

Message
The command failed due to one or more ports having both long-distance and ISL R_RDY Modes enabled. Use
portcfglongdistance and portcfgislmode to disable it before proceeding.
Probable Cause and Recommended Action
The firmwareDownload operation was attempting to downgrade a system to Fabric OS v.0.0 or lower
with both long-distance and ISL R_RDY modes enabled.
The portCfgISLMode and portCfgLongDistance modes cannot both be enabled at the same time;
otherwise, fabric segmentation occurs, so the firmware download operation failed.
Disable either the long-distance on the port using the portCfgLongDistance command, or the ISL
R_RDY mode using the portCfgISLMode command on the port or ports. Retry the firmware download
operation.
Message
The command failed due to one or more ports having EX/VEX port configuration enabled. Use
portcfgexport/portcfgvexport to disable it before proceeding.
Probable Cause and Recommended Action
The firmware download operation was attempting to downgrade a system to Fabric OS v5.0.0 or lower
with ports with EX or VEX configuration enabled. Ports with EX or VEX configuration enabled are not
supported in firmware v5.0.0 or lower, so the firmware download operation failed.
Disable either the EX port configuration using the portCfgExPort command, or the VEX port
configuration using the portCfgVexPort command. Retry the firmware download operation.
Message
Cannot downgrade to version 4.2 or lower. Please downgrade to 5.0 or 4.4 first and then download the
desired version.
Probable Cause and Recommended Action
The firmware download operation was attempting to downgrade a system from Fabric OS v5.1.0 directly to
firmware v4.2.0 or lower. This firmware jump is not supported, so the firmware download operation
aborted.
Downgrade the system to firmware v4.4.0 or v5.0.0 first, and then downgrade to the desired firmware
version.
Message
The command failed due to network timeout.
Probable Cause and Recommended Action
The firmware download operation was attempting to upgrade a system from Fabric OS v4.2.0 or lower
directly to firmware v5.1.0. This firmware jump is not supported, so the firmware download operation
aborted.
Note that the message is from the currently running switch firmware, which may be v4.2.0 or lower.
Upgrade the system to firmware v4.4.0 or v5.0.0 first, then upgrade to firmware v5.1.0.
