HP XC System Software Installation Guide Version 2.1

Test failures and warnings are clearly rep orted, and the log file contains some
troubleshooting information. In some cases, the errors might be o bvious, and the test
output is terse. For example, an LSF HPC test might fail, and the log file message migh t
say that LSF HPC has not been configured.
See the ovp
(8) m anp age and the HP XC System S oftware Administration Guide for more
information about verifyin g individual cluster components on demand.
Interconnect diagnostic tests are documented in the Installation and Operatio n G uid e for y our
model of HP cluster platform as well as in the HP XC System Software Administration Guide.
When all OVP tests pass, proceed to Section 5.2 to create a baseline snapshot of the
configuration database.
5.2 Take a Snapshot o f the Database
After running the O V P to verify the successful installation an d con figuration of your system,
HP recommends that you take a snapshot of the system configuration database to create a
baseline version. A baseline copy of the database may be useful should you have to restore the
database to its original state.
Enter the following co mmand to back up the system configuratio n database to a file in the
current directory:
# managedb backup ./filename
You can save the backup file to any directory of your choice, and you m ay w ant to add a date
and time stamp to the file name to easily determine when the backu p file was created.
Depending upon your corporate policy for manag ing system an d database backu ps, you may also
want to consider storing the database backup file on a remote system as an additional precaution.
The HP XC System Software Administratio n G uide provides informatio n about basic database
management com m a nds. Fo r complete information ab out managing your MySQL database,
refer to the MySQ L Reference Manual, which is located at the following U RL:

5.3 Create a B
aseline Report of Your System Configuration
The sys_check utility is a data collection to ol that is used to diagnose system errors and
problems. Use the sys_check utility now to create a baseline repo rt o f yo ur system’s
configuration (software and hardware).
The sys_check utility collect s confi gur ation data for only the nod e on which it is run unless
you set and export the SYS_CHECK_SYSWIDE variable, which collects configuration data for
all n odes i n the XC system .
Use the following com m and to invoke the sys_check utility in its simplest for m :
# export SYS_CHECK_SYSWIDE=1
# sys_check > /tmp/filename.html
By default, the sys_check util ity creates the report in HTML format , but there is an option to
create a text version. You can redirect the output of the sys_check report to the directory and
file name of your cho ice.
Refer to the HP XC System Software Administration Guide and the sys_check
(8) manpag e
for more information ab out this utility and i ts options.
5.4 You Are Done
Yo ur XC system is now fully installed, config ured, and operational.
