Troubleshooting the Adapter 69
▼
Analyze a Port Hang
1. If the interface encounters a soft hang, replumb the device.
■
For Oracle Solaris 10, use the
ifconfig
(1M) command.
■
For Oracle Solaris 11, use the
dladm
(1M) command.
2. If the interface encounters a hard hang, reboot the system.
If the interface encounters another hard hang, try to capture the trace information
by using the
dtrace
(1M) command, as in the following example.
3. If the system is panicked, retrieve the crash dump in
/var/crash/
hostname .
Note –
If the interface encountered a hard hang or a panic, file a CR at Oracle
Support. Attach the last page of the
dtrace
(1M) output or the crash dump file to the
CR.

Analyze Slow Network Performance
The Adapter supports several driver parameters that affect the performance of the
ports. See
“Driver Parameters (Oracle Solaris OS)” on page 44 for more information
about the default values.
1. Use the
truss
(1M) command against the process ID of the network application
to view the network performance.
2. Look for NIS , DNS , and network routing outages.
If you find any issues, fix them before proceeding.
# detrace -F -m ‘ixgbe{trace(timestamp0}’\
> /tmp/dtrace.out
# truss -p
