HP XC System Software Administration Guide Version 3.2

health to the network, either to a log file for generic usage or through a MySQL database (as is
the case in HP XC systems). In addition to logging errors in the QsNet database, the swmlogger
daemon also logs all errors to the /var/log/messages file. See the diagnostics section of the
installation and operation guide for your model of HP cluster platform for additional information
on the generic use of swmlogger.
The MySQL database for qsnet is created automatically during the configuration phase of the
HP XC system installation and the swmlogger daemon is configured to run on the head node.
Use the qsdiagadm and the qsneterr utilities to report information from the qsnet database.
The qsdiagadm Utility
A useful function of the Quadrics qsdiagadm utility is to display a diagnostic history for the
HP XC system, as shown in the following example:
# qsdiagadm
date time qsdiagadm: diags database created (QMS64,rails=1)
date time qsctrl: passed power control check (on)
date time qsctrl: passed population check (ok)
date time qsctrl: passed bus control check (ok)
date time qsctrl: passed gateway check (bootp,0.0.0.0)
.
.
.
date time qsctrl: passed bus control check (ok)
date time qsctrl: passed gateway check (bootp,0.0.0.0)
date time qsctrl: passed module heartbeat check
date time qsctrl: passed firmware version check (43-4081899)
date time qsctrl: passed tftp server check (172.20.0.16)
date time qsctrl: passed upgrade file check (503-upgrade.tar)
date time qsctrl: passed broadcast top check
.
.
.
The qsneterr Utility
The Quadrics qsneterr utility reports on the network errors logged by the swmlogger daemon
in the diagnostics database. The default action is to print summaries sorted by time and by
module.
20.4.2.2 The qselantestp Diagnostic Tool
This tool runs the qselantest diagnostic tool in parallel on all the nodes of the HP XC system.
The qselantest diagnostic tool verifies the presence of the QM500 adapter in a node and
verifies the clock speed, thread processor, SDRAM, PCI_X connectivity, the QsNet
II
link interface,
the direct memory access (DMA) latency, and the link bandwidth between the QM500 adapter
and the switch port to which it is connected.
Note:
Because this diagnostic tool uses the adapter and the link 100 percent of the time during testing,
it has significant impact on machine performance.
The command format for this utility is as follows:
qselantestp-[-help]-[-d log-directory]-[-rrail]-[-clean]-[-N nodelist]
The options are defined as follows:
-d log-directory
Specifies the directory in which the logs are to be placed. The default
directory is /var/log/diag/quadrics/qselantestp.
