Chapter 2 Setting Up XSCF 2-97
Note – (1) DR : Abbreviation for Dynamic Reconfiguration. This function
dynamically adds a system board to a domain or deletes it from a domain. For
details on DR, see the
Dynamic Reconfiguration User’s Guide .
Note – (2) Specified or displayed by the DCL. When the system board uses kernel or
I/O, for details of the DR operation and notation, see the Dynamic Reconfiguration
User’s Guide .
Note – (3) Although a CMU with two CPUMs can be configured into Quad-XSB
mode on an M8000/M9000 server, be aware of the following points:
-
Only an XSB with at least one valid CPUM and memory can be configured
into a domain.
-
Memory within an XSB that does not have a CPUM becomes unavailable.
The result is loss of access to half the installed memory on the CMU.
-
You can add DIMMs to a CMU, but you cannot reconfigure memory resident on a
CMU to the valid XSBs to prevent that memory from becoming unavailable.
-
The server generates a "configuration error" message for those XSBs that do not
have a CPUM and memory.
For details of components such as CPU/Memory Board unit, I/O unit, and
Motherboard unit, see the
Service Manual for your server.
