10 Dynamic Reconfiguration
The "Dynamic Reconfiguration" (DR) functionality described in this section exists on
BS2000 partitions of SX servers as of the SX150 model series, both native BS2000 and
VM2000 being able to run in a BS2000 partition.
Dynamic Reconfiguration of Solaris partitions is possible as already on servers of the
SX130 and SX140 model series.
10.1 Functional scope, concepts and applications
The following sections describe the functional scope, features and prerequisites for DR, the
DR concept for BS2000, applications for DR, and recommendations and DR scenarios
based on an example.
10.1.1 Functional scope and features
The PRIMEPOWER Enterprise Servers – the hardware basis for SX150 servers – offer not
only the option of dividing the hardware statically in partitions consisting of one or more
system boards, but, with Dynamic Reconfiguration (DR), also the option of removing
system boards from or adding them to a partition during ongoing operation, i.e. dynamically.
The partitions of a server as of the SX150 model series use the system boards in extended
system board mode (XSB mode):
The hardware unit which can be added or removed during DR is the extended system board
(XSB), a subunit of the system board.
An XSB is either integrated into a partition or contained in the pool of free XSBs (XSB
system board pool). Further more an XSB can be assigned to one or to no partition.
An XSB can be configured into a partition if it is contained in the XSB system board pool
and is not assigned to another partition.
An XSB can be removed from a partition if it is integrated in this partition or assigned to it
(see
"The XSB attributes "integrated" and "assigned"" on page
303). In the first case a DR
action (addition or removal) for this XSB can only be performed within the partition; in the
second case the XSB can be assigned to any partition.
