HP XC System Software Administration Guide Version 3.2

6.2.3 Displaying Blade Enclosure Information
You can use the shownode command to provide information for the HP XC system with HP
BladeSystems. With this command, you can:
• Display the names of the blade enclosures and the nodes (server blades) within them.
• List all the blade enclosures in the HP XC system and, for each, the nodes within them.
• To list the nodes for a specified blade enclosure.
• To list the blade enclosure for a specified node.
For more information, see shownode(1).
6.3 Finding and Setting System Attribute Values
The dbsysparams command finds the value of a specified attribute or sets an attribute to a
given value in the hptc_system table of the CMDB.
CAUTION:
Do not reset any database parameters. Doing so could interfere with the integrity of the database.
If this happens, you must reinstall the HP XC system and any additional software.
For additional information on the dbsysparams command, see dbsysparams(8).
6.4 Backing Up the Configuration Database
The managedb backup command enables you to copy all the data from the configuration and
management database into a backup file; the database remains intact during the backup. You
can use this backup file to restore the database at a later time, if needed.
You must be superuser to use this command.
Following is an example of the managedb backup command that backs up the CMDB:
# managedb backup
If you do not specify a file name, the managedb backup command stores the data in a file
whose name is /var/hptc/database/cmdbbackup-YYMMDDhhmmss.sql, where
YYMMDDhhmmss is a date and time stamp.
Use the managedb restore command to reinstate the database from the backup file.
For more information, see managedb(8).
Note:
The system administrator, following site policy guidelines, is responsible for determining how
often to back up the CMDB.
6.5 Restoring the Configuration Database from a Backup File
Use the managedb restore command to restore the CMDB from a backup file.
The following commands display the name of the backup file in the /var/hptc/database
directory and restore the CMDB from the backup file found there:
# ls /var/hptc/database/cmdbbackup-*.sql
/var/hptc/database/cmdbbackup-datetimestamp.sql
# managedb restore /var/hptc/database/cmdbbackup-datetimestamp.sql
6.6 Archiving Sensor Data from the Configuration Database
The managedb archive command enables you to remove sensor data records from the log
tables. These log tables are any tables in the configuration and management database that end
