Analyze Why the Link Is Not Up After Back-To-Back Cable Connection (Oracle Solaris x86)

# 

truss -p 

PID

2.

Look for 

NIS

, 

DNS

, and network routing outages.

If you find any issues, fix them before proceeding.

3.

View the I/O statistics to ensure that there are no bottlenecks on the disk.

# 

iostat -xcn 5

If you discover a bottleneck, set the logging to dump to the 

/tmp

 directory. Then retest to ensure

that the new configuration improved performance.

4.

Use the 

vmstat

 and the 

mpstat

 commands to check that none of these conditions

exist:

■

CPU is pegged.

■

CPU is receiving too many interrupts.

■

Memory is low.

■

Page faults are occurring.

■

Contention for resources causes too many spins on mutex (

smtx

).

For more information, refer to the Oracle Solaris 

vmstat

(1M)

 man page or the 

mpstat

(1M)

 man

page.
If the performance issue points to the driver, profile the call stack for 

bnxt

 by using the 

DTrace

script. For more information about the 

DTrace

 script, go to 

My Oracle Support
