Chapter 7
Maintenance
This chapter describes the daily maintenance of the CPU blade and precautions when relocating or
storing the CPU blade.

MAKING BACKUP COPIES

NEC recommends you make backup copies of your valuable data stored in hard disk drives of the
CPU blade on a regular basis. For backup storage devices suitable for the CPU blade and backup
tools, consult with your service representative.
When you have changed the hardware configuration or BIOS configuration, select "System
Information Management" and then "Save" of the Off-line Maintenance Utility to make a backup
copy of the system information.
Also make a backup copy of the disk array configuration data if your system is in the array
configuration. When your hard disk drives have been auto-rebuilt due to a failure, it is
recommended to make a backup copy of the configuration data. To make a backup copy of the
configuration data, refer to the manual that comes with the disk array controller.
