2. Credit recovery enhancements
SYNTAX The credit recovery command syntax has been enhanced to support on-demand checking of certain
types of backend ports for credit loss.
bottleneckmon --cfgcredittools -intport -recover [off | onLrOnly | onLrThresh]
bottleneckmon --cfgcredittools -intport -check slot/port,VC
DESCRIPTION Add the following text at the end of the section "Credit recovery on backend ports"
If you suspect credit loss on a particular virtual channel (VC) on a particular backend port, use the -check
option to examine that particular backend port and VC for credit loss.
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.
NOTES 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.
OPERANDS Add the following text to the Operand Section:
backend port credit recovery commands
You can use the -intport option with the -recover option to either configure credit recovery options on a
back end port, or you use it with the -check option to examine a port for credit loss. Both options are
exclusive.
--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.
