5 fruReplace fruReplace This command is no longer supported in Fabric OS v6.4.1 and later. Although you can still execute the command, it causes problems and should not be used. It will be removed in v7.0.0. Refer to the WWN Card Remove and Replace Procedure (53-1000832-05) for information on how to replace a WWN card without this command. Documentation updates for Fabric OS v6.4.2 bottleneckMon This command has been enhanced with additional command options to support credit recovery on external backend ports. SYNTAX The syntax for added credit recovery support is as follows: bottleneckmon --cfgcredittools -intport -recover [off | onLrOnly | onLrThresh] bottleneckmon--showcredittools DESCRIPTION NOTES Add the following text to the Description section: Credit recovery on backend ports Use the --cfgcredittools commands to enable or disable credit recovery of external backend ports and to display the configuration. When this feature is enabled, credit is recovered on external backend ports (ports connected to the core blade or core blade backend ports) when credit loss has been detected on these ports. When used with the -recover onLrOnly option, the recovery mechanism takes the following escalating actions: • When it detects credit loss, it performs a link reset and logs a RASlog message (RAS Cx-1014). • If the link reset fails to recover the port, the port reinitializes. A RASlog message is generated (RAS Cx-1015). Note that the port reinitialization does not fault the blade. • If the port fails to reinitialize, the port is faulted. A RASlog message (RAS Cx-1016) is generated. • If a port is faulted and there are no more online backend ports in the trunk, the core blade is faulted. (Note that the port blade will always be faulted). A RASlog message is generated (RAS Cx-1017). When used with the -recover onLrThresh option, recovery is attempted through repeated link resets and a count of the link resets is kept. If the threshold of more than two link resets per hour is reached, the blade is faulted (RAS Cx-1018). Note that regardless of whether the link reset occurs on the port blade or on the core blade, the port blade is always faulted. For more information on the RASlog messages, refer to the Fabric OS Message Reference. Add the following text to the Notes section: The credit recovery commands are supported only on backend ports of Condor, Condor 2, and Condor 3-based blades in the Brocade DCX, DCX-4S, DCX 8510-8, and DCX 8510-4 chassis. 34 Fabric OS Documentation Updates 53-1002063-09
