Administration and Diagnostics Utilities - Oracle Exadata Recipes: A Problem-Solution Approach - page 177

How It Works
The CheckSWProfile.sh script is supplied on each Exadata Compute and Storage Server and can be found in
/opt/oracle.SupportTools/CheckSWProfile.sh . CheckSWProfile.sh processes the list of InfiniBand switch names
and passwords provided, logs in to each switch, and runs a series of InfiniBand commands such as version show ,
module-firmware , and also copies the contents of /etc./opensm/opensm.conf to temporary files in /tmp .
CheckSWProfile.sh also conducts an RPM search on each switch to confirm software versions. When complete, the
utility will parse the temporary output files and display its status to the calling window.
The CheckSWProfile.sh utility is typically executed as a pre-patch or post-patch procedure but can be executed
at any time.

7-14. Verifying Your InfiniBand Network Topology
Problem
You wish to report your Exadata InfiniBand network topology.

Solution
With Exadata, Oracle supplies a script called /opt/oracle.SupportTools/ibdiagtools/verify-topology , which
is used to do just what its name implies, validate your InfiniBand network layout. To execute this utility, log in to a
compute server or storage cell as root , change directories to /opt/oracle.SupportTools , and execute the command
below:

[root@cm01dbm01 ~]# cd /opt/oracle.SupportTools/ibdiagtools/
[root@cm01dbm01 ibdiagtools]# ./verify-topology

[ DB Machine Infiniband Cabling Topology Verification Tool ]
[Version IBD VER 2.c 11.2.2.4.2 111221]
Leaf switch found: cm01sw-ib2 (21284697f9a0a0)
Leaf switch found: cm01sw-ib3 (2128469c6da0a0)

Found 2 leaf, 0 spine, 0 top spine switches

Check if all hosts have 2 CAs to different switches...............[SUCCESS]
... Output omitted
Spine switch check: Are any Exadata nodes connected ..............[SUCCESS]
Spine switch check: Any inter spine switch links..................[SUCCESS]
Spine switch check: Any inter top-spine switch links..............[SUCCESS]
Spine switch check: Correct number of spine-leaf links............[SUCCESS]
Leaf switch check: Inter-leaf link check..........................[SUCCESS]
Leaf switch check: Correct number of leaf-spine links.............[SUCCESS]
[root@cm01dbm01 ibdiagtools]#

■ You must execute the verify-topology command from the /opt/oracle.SupportTools/ibdiagtools
directory because the script attempts to read the VERSION_FILE file from the current working directory. not doing so will
yield a head: cannot open 'VERSION_FILE' for reading: No such file or directory error message .
