HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual page 190

Message
Cannot upgrade directly to 5.3.0. Upgrade your switch to 5.1 or 5.2 first before
upgrading to the requested version.
Probable cause and recommended action
If the switch is running 5.0.0 or earlier, you will not be allowed to upgrade directly to 5.3.0 because of the
"two-version" rule.
Upgrade your switch to Fabric OS version 5.1.0 or 5.2.0 before upgrading to 5.3.0
Message
Cannot upgrade due to the presence of an existing zone named "broadcast". Rename
this zone before proceeding.
Probable cause and recommended action
If the switch is running 5.1.0 or 5.2.0, and if an existing zone is named "broadcast", the user will not be
allowed to upgrade the switch to the 5.3.0 firmware, as broadcast zone gets a special meaning in 5.3.0.
Use the zoneDelete command to delete the zone.
Message
The command failed due to presence of long-distance ports in LS mode. Please
remove these settings before proceeding.
Probable cause and recommended action
The firmware download operation was attempting to downgrade a system to Fabric OS 5.0.0 or earlier
with long-distance ports in LS mode. Long-distance ports in LS mode is not supported in firmware 5.0.0 or
earlier, so the firmware download operation failed.
Change the long distance port setting to a supported distance setting using the portCfgLongDistance
command and then retry the firmware download operation. The supported settings are:
L0 Specify L0 to configure the port to be a regular switch port. A total of 20 full-size
frame buffers are reserved for data traffic, regardless of the port's operating speed;
therefore, the maximum supported link distance is 10 km, 5 km, or 2.5 km for the port
at speeds of 1 Gbps, 2 Gbps, or 4 Gbps respectively.
L0.5 Specify L0.5 (portCfgShow displays the two-letter code as LM) long distance to
support a long distance link of up to 25 km. A total of 12, 25, or 50 full-size frame
buffers are reserved for data traffic for the port at speeds of 1 Gbps, 2 Gbps, or 4
Gbps respectively.
L1 Specify L1 long distance to support a long distance link up to 50 km. A total of 25,
50, or 100 full-size frame buffers are reserved for data traffic for the port at speeds of
1 Gbps, 2 Gbps, or 4 Gbps respectively.
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 Gbps, 2 Gbps, or 4 Gbps respectively.
LE Specify LE mode is used 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 Gbps, 2
Gbps, or 4 Gbps, 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.
