the XSCF and an encryption function using SSH and SSL. Operator errors and
unauthorized access during system operation are recorded in a log. The system
administrator can use these functions to investigate the cause of a system problem.
3.2.2.3 System Status Management
The XSCF provides functions as XSCF operations for displaying the system
configuration status, creating and changing a domain configuration definition, and
starting and stopping domains. Also, the XSCF provides the DR function, which
assists in dynamically changing a system board configuration during domain
operation. Thus, domain resources can be optimized for job operations. Moreover,
the XSCF in linkage with the Solaris Operating System manages CPU, memory, and
I/O resources.
3.2.2.4 Error Detection and Management
The XSCF constantly monitors the system status so that the system can operate
stably. When any error is detected in the system, the XSCF immediately collects error
information about the hardware (hardware log) and analyzes it to identify the error
location. To continue operation, the XSCF degrades the relevant component or
domain as necessary according to error conditions or it resets the system, thereby
preventing the problem from occurring again. The user can take prompt action for
problems since easy-to-understand and accurate information on hardware errors and
fault locations are thus provided to the user.
3.2.2.5 Remote System Control and Monitoring
The XSCF provides functions for monitoring the server through an Ethernet
connection so that the user can remotely manage the server. Moreover, a function for
reporting error information to the system administrator and a remote console input-
output function are supported. System availability is thus increased.
3.2.2.6 Resource Management
XSCF manages hardware resources on configured domains and system boards. As
for the resource management, DR function that enables dynamic reconfiguration of
domains is provided. Moreover, COD is provided to realize resource management
CPUs that is purchased by license.
