Fibre Channel switch is Brocade DCX 8510 and FOS version is 7.4.1 D ( or B ).

Cause

Brocade has determined that the message being seen on Oracle hosts is due to a new feature that was added to FOS 7.3.x and above. Read Diagnostics Parameter (RDP) polling was added to FOS, which allows the switch to poll the remote HBA of each port for SFP statistics. This feature is enabled on the switch by default, and the following line from the configshow output displays the current feature setting:

fabric.rdp_poll_cycle:1

With a setting of 1, the switch will poll the remote HBAs every hour for statistics.

Solution

In order to stop the messages, the remote polling feature can be disabled non-disruptively via the configure command as seen in the below example. The switch does not need to be disabled to make the change:

switch:root> configure

Not all options will be available on an enabled switch.
To disable the switch, use the "switchDisable" command.

Configure...

Fabric parameters (yes, y, no, n): [no]
D-Port Parameters (yes, y, no, n): [no]
RDP Polling Cycle(hours)[0 = Disable Polling]: (0..24) [1] 0 <<<--- enter 0 here
Zoning Operation parameters (yes, y, no, n): [no]
System services (yes, y, no, n): [no]
ssl attributes (yes, y, no, n): [no]
rpcd attributes (yes, y, no, n): [no]
cfgload attributes (yes, y, no, n): [no]
webtools attributes (yes, y, no, n): [no]

switch:root> configshow -all |grep rdp
fabric.rdp_poll_cycle:0

Entering 0 for the "RDP Polling Cycle" option will disable the feature for all ports on the switch, and "fabric.rdp_poll_cycle:0" indicates the feature is disabled for that switch. If virtual switches are involved, the feature will need to be disabled for each virtual switch. It is not possible to selectively disable the feature for specific ports.

In addition to the switch feature, BNA 12.4.x and above may also instruct the switch to use the Remote Polling feature. The setting can be found using the following steps in BNA:

1) Launch BNA client
2) Go to Monitor a Configuration Policy Manager
3) Select and Edit the "Default SAN Policy"
4) Navigate to "Switch/Router Checks" tab

BNA 12.4.x contains a defect where the SFP Metrics check is enabled in the default SAN policy, despite not being listed in the Selected Checks. The feature can be disabled via the following actions. The SFP Metrics check is moved to the Selected Checks, then immediately be moved back to the Available Checks. Once OK is selected to save the changes, these actions will remove the SFP Metrics check from the Selected Checks in the default SAN policy. This defect will be fixed in upcoming BNA release 14.0.1.
