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 Oracle Solaris OS 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
The XSCF manages hardware resources on configured domains and system boards.
Resource management provides Dynamic Reconfiguration (DR) and Capacity on
Demand (COD) functions.
Dynamic Reconfiguration (DR)
DR enables users to add, remove or exchange system boards while the domains that
contain these boards remain up and running. It also enables dynamic
reconfiguration of domains.
For details on DR, see the SPARC Enterprise M4000/M5000/M8000/M9000 Servers
Dynamic Reconfiguration (DR) User’s Guide.
