  22 DESCRIPTION
  23        The dynamic reconfiguration (DR) driver consists of a platform-
  24        independent driver and a platform-specific module. The DR driver uses
  25        standard features of the Solaris operating environment whenever
  26        possible to control DR operations and calls the platform specific
  27        module as needed. The DR driver creates minor nodes in the file system
  28        that serve as attachment points for DR operations.
  29 
  30 
  31        The DR driver provides a pseudo-driver interface to sequence attach and
  32        detach operations on system boards using file system entry points
  33        referred to as "attachment points." The attachment point form depends
  34        on the platform.
  35 
  36    Sun Enterprise 10000 Server
  37        On the Sun Enterprise 10000 server, the DR driver consists of a
  38        platform-independent driver (ngdr) and a platform-specific module
  39        (ngdrmach).
  40 
  41 
  42        The domain configuration server (DCS) accepts DR requests from the
  43        system services processor (SSP) and uses the libcfgadm(3LIB) interface
  44        to initiate the DR operation. After the operation is performed, the
  45        results are returned to the SSP. For more information about the DCS on
  46        the Sun Enterprise 10000, refer to the dcs(1M) man page and the Sun
  47        Enterprise 10000 Dynamic Reconfiguration User Guide.
  48 
  49 
  50        The DR driver creates physical attachment points for system board slots
  51        that takes the following form:
  52 
  53          /devices/pseudo/ngdr@0:SBx
  54 
  55 
  56 
  57        Where x represents the slot number (0 to 15) for a particular board.
  58 
  59 
  60        The cfgadm_sbd(1M) plugin creates dynamic attachment points that refer
  61        to components on system boards, including CPUs, memory, or I/O devices.
  62        Refer to the cfgadm_sbd(1M) man page for more details.
