bottleneckMon 5 NOTES OPERANDS If the command detects complete credit loss, it reports the information. If, in addition, you have enabled link resets on backend ports, this command will perform a link reset on the link in an attempt to recover from the problem. You must explicitly initiate this check and it is a one-time operation. In other words, this command does not continuously monitor for credit loss in the background. Detection of credit loss takes 2-7 seconds, after which the results of the operation are displayed. A Link Reset also generates a RASlog message. Add the following text to the Notes section: The -check option is supported only on modular switches, and only on Condor 2-Condor 2 links between Condor 2 core blades and Condor 2 port blades. AP blades are not supported. Add the following text to the Operand Section: backend port credit recovery commands You can use the -intport option either with the -recover option to configure credit recovery options on a back end port, or you can use it with the -check option to examine a port for credit loss. You cannot use both options at the same time. --cfgcredittools -intport -recover Configures credit recovery options for backend ports. Use one of the following required recovery options to configure credit recovery: onLrOnly Enables the backend port recovery feature in link reset mode. onLrThresh Enables the backend port recovery feature in link reset threshold mode. off Disables the backend port credit recovery feature. --cfgcredittools -intport -check Performs the on-demand detection of credit loss on a given backend port and VC. This operand is optional and exclusive; when you specify this option you cannot use the --cfgcredittools -intport -recover options at the same time. You must specify a port and a VC, separated by a comma. A space before the comma is not permitted. slot/blade_port Specifies the backend port that is to be examined for credit loss. The port number must be the blade port number, since this is a backend port. The blade port number can be located in the Bpt column output of the bladeportmap command. Note that the bladeportmap command requires root permissions. VC Specifies the Virtual Channel number. The valid range is 1 to 31.VC 0 is invalid. --linkreset slot/blade_port Performs a link reset on the specified front-end or backend blade port. The blade port number can be located in the "Bpt" column output of the bladePortMap command. The bladeportmap command requires root permissions. EXAMPLES Add the following text to the example section: Backend port credit recovery examples To examine a backend port for credit loss: switch:admin> bottleneckmon --cfgcredittools \ -intport -check 10/4,30 Started Credit loss Detection on slot 10 port 4 VC 30. Please wait.... Detected credit loss. Link Reset performed. Fabric OS Documentation Updates 39 53-1002063-09
