HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual page 194

L2 Specify L2 long distance to support a long distance link up to 100 km. A total of 50,
100, or 200 full-size frame buffers are reserved for data traffic for the port at speeds
of 1 Gbit/sec, 2 Gbit/sec, or 4 Gbit/sec respectively. For previously released
switches (Bloom1-based), the number of frames buffers is limited to 63.
LE Specify LE mode is for E_Ports for distances beyond 5 Km and up to 10 Km. A total
of 5, 10, or 20 full-size frame buffers are reserved for port speeds of 1 Gbit/sec, 2
Gbit/sec, or 4 Gbit/sec, respectively. LE does not require an Extended Fabrics
license.
LD Specify LD for automatic long-distance configuration. The buffer credits for the given
E_Port are automatically configured, based on the actual link distance. Up to a total
of 250 full-size frame buffers are reserved, depending upon the distance measured
during E_Port initialization. If the desired distance is provided, it is used as the upper
limit to the measured distance. For Bloom1-based systems, the number of frame
buffers is limited to 63.
LS Specify LS mode to configure a long-distance link with a fixed buffer allocation. Up
to a total of 250 full-size frame buffers are reserved for data traffic, depending on the
desired distance value provided with the portCfgLongDistance command. For
Bloom1-based systems, the number of frame buffers is limited to 63.
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.
