The following two examples show a successful run on a 16 port interconnect: # ./qsnet2_dmatest -a -e -se -dm -n10000 -RD 1m mnfr_dmatest: master self=0 peer=0 source 0x2000000000602000 dest 0x200000000460a000 event 0x2000000000703fe0 done 0x2000000004607fa8 mnfr_dmatest: using route'D'-> 00000000000000000000000000002008 0: reps 10000 min 1048576 max 1048576 inc 0 (batch 1) dma test will run for approx. 10 secs. please wait.. 0: 1048576 bytes 1145.02 uSec 915.77 MB/s # ./qsnet2_dmatest -a -e -se -dm -n10000 -R4,D,D 1m mnfr_dmatest: master self=0 peer=0 source 0x2000000000602000 dest 0x200000000460a000 event 0x2000000000703fe0 done 0x2000000004607fa8 mnfr_dmatest: using route '4,D,D' -> 0000000000000000000000000088000c 0: reps 10000 min 1048576 max 1048576 inc 0 (batch 1) dma test will run for approx. 10 secs. please wait.. 0: 1048576 bytes 1153.01 uSec 909.43 MB/s The following command example simulates an error. It is intended to test the level 3 chips in the network. However, because the 16 port interconnect has only 2 levels, the script fails and reports that the link has failed: # ./qsnet2_dmatest -a -e -se -dm -n10000 -R4,4,D,D,D 1m mnfr_dmatest: master self=0 peer=0 source 0x2000000000602000 dest 0x200000000460a000 event 0x2000000000703fe0 done 0x2000000004607fa8 mnfr_dmatest: using route '4,4,D,D,D' -> 000000000000000000000000888c000c mnfr_dmatest: not making expected progress, checking errors mnfr_dmatest: total errors reported during test: 0 You can also use the qsnet2_dmatest utility to calculate a static route through the network by deriving the route data derived from the nodeid of the node on which you run the test. Use the -U option to calculate the static route as follows: # qsnet2_dmatest -UN -se -dm -e 0 1m Where N = an integer in the range 1 through 4. Specifying 1 will test only the 1st level of routes through the interconnect. Specifying 2 tests the first and second level, and so on to all four levels. The following sample output show use of the -U option. 0: reps 1000 min 0 max 1048576 inc 0 (batch 1) 0: 0 bytes 2.67 uSec 0.00 MB/s 0: 4 bytes 2.78 uSec 1.44 MB/s 0: 8 bytes 2.77 uSec 2.89 MB/s 0: 16 bytes 2.80 uSec 5.72 MB/s 0: 32 bytes 2.79 uSec 11.46 MB/s 0: 64 bytes 2.84 uSec 22.54 MB/s 0: 128 bytes 3.01 uSec 42.48 MB/s 0: 256 bytes 3.11 uSec 82.39 MB/s 0: 512 bytes 3.39 uSec 151.03 MB/s . . . 0: 1048576 bytes 1155.90 uSec 907.15 MB/s Node Network Error Report: - No Errors 12.5 Using the qsnet2_level_test Utility When running the HP XC operating environment, you can use the qsnet2_level_test utility for diagnosing interconnect problems. To run the command on all nodes simultaneously, use the /cluster/bin/crsh command. If all nodes do not complete the test, the command terminates after a timeout period, killing any incomplete processes. 12-12 Maintenance and Diagnostic Procedures

The following command example simulates an error. It is intended to test the level
3 chips in the network. However, because the 16 port interconnect has only 2
levels, the script fails and reports that the link has failed:
#
./qsnet2_dmatest -a -e -se -dm -n10000 -R4,4,D,D,D 1m
mnfr_dmatest: master self=0 peer=0
source 0x2000000000602000 dest 0x200000000460a000 event 0x2000000000703fe0
done 0x2000000004607fa8
mnfr_dmatest: using route ’4,4,D,D,D’ -> 000000000000000000000000888c000c
mnfr_dmatest: not making expected progress, checking errors
mnfr_dmatest: total errors reported during test: 0
You can also use the
qsnet2_dmatest
utility to calculate a static route through
the network by deriving the route data derived from the
nodeid
of the node on
which you run the test. Use the
-U
option to calculate the static route as follows:
#
qsnet2_dmatest -U
N
-se -dm -e 0 1m
Where
N
= an integer in the range 1 through 4. Specifying 1 will test only the
1st level of routes through the interconnect. Specifying 2 tests the first and
second level, and so on to all four levels. The following sample output show use
of the
-U
option.

12.5 Using the qsnet2_level_test Utility
When running the HP XC operating environment, you can use the
qsnet2_level_test
utility for diagnosing interconnect problems. To run the
command on all nodes simultaneously, use the
/cluster/bin/crsh
command.
If all nodes do not complete the test, the command terminates after a timeout
period, killing any incomplete processes.
