NAME
       dr, drmach, ngdr, ngdrmach - Sun Enterprise 10000  dynamic reconfigura‐
       tion driver

SYNOPSIS
       dr

       drmach

       ngdr

       ngdrmach

DESCRIPTION
       The dynamic reconfiguration (DR) driver consists of a platform-indepen‐
       dent driver and a platform-specific module. The DR driver uses standard
       features of the Solaris operating environment whenever possible to con‐
       trol  DR	 operations  and calls the platform specific module as needed.
       The DR driver creates minor nodes in the	 file  system  that  serve  as
       attachment points for DR operations.

       The DR driver provides a pseudo-driver interface to sequence attach and
       detach operations on system  boards  using  file	 system	 entry	points
       referred	 to  as "attachment points." The attachment point form depends
       on the platform.

   Sun Enterprise 10000 Server
       On the Sun Enterprise 10000 server, the DR driver consists of  a	 plat‐
       form-independent	 driver	 (ngdr)	 and a platform-specific module (ngdr‐
       mach).

       The domain configuration server (DCS) accepts DR requests from the sys‐
       tem  services processor (SSP) and uses the libcfgadm(3LIB) interface to
       initiate the DR	operation.  After  the	operation  is  performed,  the
       results	are returned to the SSP. For more information about the DCS on
       the Sun Enterprise 10000, refer to the dcs(1M) man  page	 and  the  Sun
       Enterprise 10000 Dynamic Reconfiguration User Guide.

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

       /devices/pseudo/ngdr@0:SBx

       Where x represents the slot number (0 to 15) for a particular board.

       The cfgadm_sbd(1M) plugin creates dynamic attachment points that	 refer
       to components on system boards, including CPUs, memory, or I/O devices.
       Refer to the cfgadm_sbd(1M) man page for more details.
