How It Works
Oracle provides several utilities and commands to validate your InfiniBand network on Exadata. Table 7-4
summarizes these utilities.

Table 7-4. InfiniBand diagnostics utilities and scripts

Utility Usage Description

ibdiagnet From compute or storage server, run

# /usr/bin/ibdiagnet

Validates InfiniBand link status,
performance counters report, and
other information

ibqueryerrors.pl From compute or storage server, run
#/usr/sbin/ibqueryerrors.pl

Reports InfiniBand network
transmission errors

infinicheck From the compute or storage server, change directories

to /opt/oracle.SupportTools/ibdiagtools and run
# ./infinicheck -g [text file listing nodes]
-u root

network performance tests

ip From an InfiniBand switch, run

# ip -s link show

7-16. Connecting to Your Cisco Catalyst 4948 Switch and
Changing Switch Configuration
Problem
You wish to connect to your embedded Cisco Catalyst 4948 switch inside your Exadata rack to perform configuration
changes.

Solution
First, connect a serial cable from the Cisco switch console to a laptop using the RJ45 to DB9 serial cable included with
your Exadata package. Once you've got a serial connection, connect at 9600 baud, 8 bits, no parity, 1 stop bit, and no
handshake.

Once connected, change to enable mode using the following command:

Switch> enable
Switch#
