HP XC System Software Administration Guide Version 3.2

• Links reporting IB_TIMEOUT, meaning the node is down.
• Links reporting a state other than PORT_ACTIVE, meaning the link is down.
The output that ib_prodmode_mon produces identifies the bad links so that you can take
corrective action. It resembles the following:
date time node ib_prodmode_mon:
IR0N00 - Link xc9n1 GUID 0008f10403961325 (LID 3 PORT 1)
<==> GUID 0008f10400410876 (LID 1 PORT 1 ) running at 1X
ibt1 - Link ibt1 SLOT 1 PORT 14 GUID 0008f104003f0726 (LID 2 PORT 23)
<==> R1C5-IB14 PORT 7 GUID 0008f10400410a10 (LID 617 PORT 7 ) reporting
4297 RcvErrs, which is above threshold of 2400
ibt1 - Link 0008f1040396cd64 PORT 1 GUID 0008f1040396cd65 (LID 950 PORT
1) <==> R3C10-IB58 PORT 18 GUID 0008f104004108cc (LID 589 PORT 18 )
reporting Status ALERT IB_TIMEOUT
The ib_prodmode_mon diagnostic tool searches /etc/hosts for entries whose name matches
the regular expression "IR0[NT][0–9][0–9]".
This command uses the wget command to obtain the PortCounters.csv file from the switch
and parses the output. The ib_prodmode_mon diagnostic tool generates an alert if it finds any
errors. All alerts are logged in the /var/log/messages file and the ib_prodmode_mon.log
file.
The format of this command is:
ib_prodmode_mon [--help] [--verbose] [-d directory-name]
The output from the ib_prodmode_mon is logged to
/var/log/diag/ib/ib_prodmode_mon/ib_prodmode_mon.log by default, but you can
specify another directory with the -d option. Output is displayed to the stdout to show the
progress of the diagnostic test.
This command is configured to run once each day by a crontab file in the /etc/cron.daily
directory.
20.4.4 Using Diagnostic Tools for the Gigabit Ethernet System Interconnect
The Gigabit Ethernet system interconnect is diagnosed with the standard Ethernet diagnostic
tools, including:
• tcpdump
• ifconfig
• mii-tool
For more information about these diagnostic tools, see the Linux Administration Handbook and
the corresponding manpages.
