metrocluster with brocade 300

babar — Thu, 05 Jun 2025 07:23:32 GMT

Hi all,

According to the metrocluster guide we are supposed to set the disk loop port to half duplex by:

portCfgLPort <port#>,0,0,1

The problem is brocade 300 does not have last option 1 i.e to set half duplex where as brocade 300 seems to offer only 0 (full duplex) and 2 (full duplex with fairness). Any ideas?

Regards,

Babar

You said the option is removed 6.2 onwards. I have 6.1.1a but still option 1 is not working?

According the Command Reference Manuals Part 53-1000599-03 is option 1 Supported.

duplex_mode

Specify 2 to configure the specified port as a full-duplex L_Port with fairness.
Specify 1 to configure the L_Port as a half-duplex L_Port with fairness.
Specify 0 to configure the L_Port as a full-duplex L_Port. This operand is
optional; if omitted, the default value of 0 is used.

I have check all 6.1.1 Release Notes and this command as not be changed beetwen this release

another idea what i have is, this feature is not supported in the 300 Brocade, but i'm not sure.

Another example, private_mode is supported on FC2 ( 2 GB ) Switches and Directors

Babar,

If the switch is running FOS greater than 6.1.0 then there is no half-duplex setting any more (in spite of the Brocade documentation. Set all ports attached to disk loops to Locked L-Port by entering the following command for each port number:

portcfglport <disk_port>,1,0,2

To confirm the correct settings, they can use the following 2 commands:

portCfgShow
portcfglport

Result: ON is displayed in the Locked L_port and Locked Loop Fairness.

It is also recommended that they look the speed of the ports; shelves, FCVI, Initiators and E-Ports.

The MetroCluster Guide will be updated accordingly

If the switch is running FOS greater than 6.1.0 then half-duplex is no longer available so set all ports attached to disk loops to Locked L-Port by entering the following command for each port number:
> portcfglport <disk_port>,1,0,2

To confirm the correct settings, they can use the following 2 commands:
> portCfgShow
> portcfglport
Result: ON is displayed in the Locked L_port and Locked Loop Fairness.

It is also recommended that the speed of the ports; shelves, FCVI, Initiators and E-Ports be set explicitly

The MetroCluster Guide will be updated accordingly.

Thanks.

Hello Jim!

Excuse my interference in this old discussion but why do MetroCluster Best Practices recommend to set all ports attached to disk loops to Locked L-port and Locked Loop Fairness?

Thank you if you answer.
