exds_netdiag
The
exds_netdiag
utility performs tests on and retrieves data from the networking components
in an X9720 Network Storage System. It performs the following functions:
•
Reports failed Ethernet Interconnects (failed as reported by the HP Blade Chassis Onboard
Administrator)
•
Reports missing, failed, or degraded site uplinks
•
Reports missing or failed NICs in server blades
Sample output
exds_netperf
The
exds_netperf
tool measures network performance. The tool measures performance between
a client system and the X9720 Network Storage System. Run this test when the system is first
installed. Where networks are working correctly, the performance results should match the expected
link rate of the network, that is, for a 1– link, expect about 90 MB/s. You can also run the test at
other times to determine if degradation has occurred.
The
exds_netperf
utility measures streaming performance in two modes:
•
Serial—Streaming I/O is done to each network interface in turn. The host where
exds_netperf
is run is the client that is being tested.
•
Parallel—Streaming I/O is done on all network interfaces at the same time. This test uses
several clients.
The serial test measures point-to-point performance. The parallel test measures more components
of the network infrastructure and could uncover problems not visible with the serial test. Keep in
mind that overall throughput of the parallel test is probably limited by client’s network interface.
The test is run as follows:
•
Copy the contents of
/opt/hp/mxso/diags/netperf-2.1.p13
to an x86_64 client host.
•
Copy the test scripts to one client from which you will be running the test. The scripts required
are
exds_netperf
,
diags_lib.bash
, and
nodes_lib.bash
from the
/opt/hp/mxso/
diags/bin
directory.
•
Run
exds_netserver -s <server_list>
to start a receiver for the test on each X9720
Network Storage System server blade, as shown in the following example:
exds_netserver -s glory[1-8]
