  34 The dynamic reconfiguration (DR) driver consists of a platform-independent
  35 driver and a platform-specific module. The DR driver uses standard features of
  36 the Solaris operating environment whenever possible to control DR operations
  37 and calls the platform specific module as needed. The DR driver creates minor
  38 nodes in the file system that serve as attachment points for DR operations.
  39 .sp
  40 .LP
  41 The DR driver provides a pseudo-driver interface to sequence attach and detach
  42 operations on system boards using file system entry points referred to as
  43 "attachment points." The attachment point form depends on the platform.

  47 On the Sun Enterprise 10000 server, the DR driver consists of a
  48 platform-independent driver (\fBngdr\fR) and a platform-specific module
  49 (\fBngdrmach\fR).
  50 .sp
  51 .LP
  52 The domain configuration server (DCS) accepts DR requests from the system
  53 services processor (SSP) and uses the \fBlibcfgadm\fR(3LIB) interface to
  54 initiate the DR operation. After the operation is performed, the results are
  55 returned to the SSP. For more information about the DCS on the Sun Enterprise
  56 10000, refer to the \fBdcs\fR(1M) man page and the \fISun Enterprise 10000
  57 Dynamic Reconfiguration User Guide\fR.

  60 The DR driver creates physical attachment points for system board slots that
  61 takes the following form:

  65 /devices/pseudo/ngdr@0:SB\fIx\fR
  66 .fi
  67 .in -2
  69 .sp
  70 .LP
  71 Where \fIx\fR represents the slot number (0 to 15) for a particular board.
  72 .sp
  73 .LP
  74 The \fBcfgadm_sbd\fR(1M) plugin creates dynamic attachment points that refer to
  75 components on system boards, including CPUs, memory, or I/O devices. Refer to
  76 the \fBcfgadm_sbd\fR(1M) man page for more details.
