Syntax

ibchecknet [-h][-N][topology|-C ca_name -P ca_port -t timeout]

where:

• topology is the topology file.

• ca_name is the channel adapter name.

• ca_port is the channel adapter port.

• timeout is the timeout in milliseconds.

Description

This InfiniBand command is a script that uses the topology file created by the ibnetdiscover command to scan the InfiniBand fabric to validate the connectivity and report errors from the port counters.

Options

The following table describes the options to the ibchecknet command and their purposes:

Example

The following example shows how to check error counters for all LIDs in the InfiniBand fabric with the ibchecknet command.

# ibchecknet 
#warn: counter SymbolErrors = 3121      (threshold 10) lid 25 port 255
#warn: counter RcvSwRelayErrors = 48545         (threshold 100) lid 25 port 255
#warn: counter XmtDiscards = 9789       (threshold 100) lid 25 port 255
Error check on lid 25 (Sun DCS 72 QDR FC switch o4nm2-72p-2) port all:  FAILED 
#warn: counter RcvSwRelayErrors = 56839         (threshold 100) lid 25 port 28
Error check on lid 25 (Sun DCS 72 QDR FC switch o4nm2-72p-2) port 28:  FAILED 
#warn: counter RcvSwRelayErrors = 56839         (threshold 100) lid 25 port 9
Error check on lid 25 (Sun DCS 72 QDR FC switch o4nm2-72p-2) port 9:  FAILED 
#warn: counter XmtDiscards = 9714       (threshold 100) lid 25 port 1
Error check on lid 25 (Sun DCS 72 QDR FC switch o4nm2-72p-2) port 1:  FAILED
