3.3 Quick health check for full HPC cluster system
In this section, an organized set of procedures that checks the status of all of the components
of a 775 HPC Cluster is described. The procedures help determine whether a problem is
detected, and which steps might determine the problem.
For more information: For more information about high-performance clustering by using
the 9125-F2C, see this website:

IBM Power Systems 775 for AIX and Linux HPC Solution
Description
Check all xCAT information, such as: xCAT deamon (xcatd), data in the xCAT table,
the xCAT database configuration, the status of ODBC setup, the status of hardware
connection, and the running status of nodes.
Check all DB2 information, such as: the running status of DB2 server, the xcatdb
status to connect to database from DB2 server, the health snapshot for database on
xcatdb, the path pointed of DB2 instance directory (default /var/lib/db2), the size of
DB2 database, and the DB2 license.
Check all TEAL information, such as: the status of TEAL daemon, the log information
for TEAL, the events and alerts of ISNM, SFP, LoadLeveler, PNSD, and GPFS
Check all ISNM information, such as: the running status of CNM, the connection
status of LNMC on FSP, the status of miswired links, the network topology, and the
ISR links information.
Check all NIM objects information, such as: the status of diskfull and diskless image,
the status of NIM network, the status of NIM machine for diskfull node, the status of
NIM dump, and the information of NIM bundle.
