(All): The answer to Would you like to perform fabric link speed
error analysis
indicates when iba_report -o slowlinks should be
run. If the user enters
y to this question, the Check for links configured
to run slower than supported
question is asked. If the user enters y, the
-o misconfiglinks option will also be used for iba_report. Additionally, if
the user enters
y to the Would you like to perform fabric link speed
error analysis
question, the Check for links connected with
mismatched speed potential
question will also be asked. If the user
enters
y, the -o misconnlinks option is also be used for iba_report.
Entering
y to all but the last 2 questions is recommended (these are the
defaults for each prompt). This checks all the ports in the fabric for any links
that have high error rates or are running at a lower speed than expected.
Any identified links should be diagnosed and corrected.
(Host): If the user enters
n to all of the prompts, the showallports command is
run to allow the state and symbol error counts of all host ports to be manually
reviewed. Selection of this option requires that QLogicIB OFED+ software be
installed on all hosts being checked.
Verify Hosts see each other
(Host) This will run the iba_host_admin sacache command to verify that each
host can see all the others through queries to the Subnet Administrator. For the
OFED+ stack this also verifies the Distributed SA on each host has been fully
populated.
Verify Hosts ping via IPoIB
(Host) This will run the iba_host_admin ipoibping command to verify that
IPoIB is properly configured and running on all the hosts. This is accomplished
through the InfiniBand management node pinging each host using IPoIB.
NOTE:
If the fabric is homogeneous and all links are expected to be running at full
speed, enter
y to the last two questions as well.
NOTE:
This operation requires that the hosts being queried be specified by a
resolvable TCP/IP host name. This operation will FAIL if the selected hosts
are specified by IP address. See the FastFabric Command Line Interface
Reference Guide, Selection of Hosts section for more information.
