NAME

       dr, drmach, ngdr, ngdrmach - Sun Enterprise 10000  dynamic reconfiguration driver

SYNOPSIS

       dr

       drmach

       ngdr

       ngdrmach

DESCRIPTION

       The  dynamic reconfiguration (DR) driver consists of a platform-independent driver and a platform-specific module. The DR driver uses stan-
       dard features of the Solaris operating environment whenever possible to control 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 platform-independent driver (ngdr) and a  platform-specific  module  (ngdr-
       mach).

       The  domain  configuration server (DCS) accepts DR requests from the system 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.

NAME

       cvc - virtual console driver

DESCRIPTION

       The  cvc  virtual  console  driver  is a STREAMS-based pseudo driver that supports the network console. The cvc driver interfaces with con-
       sole(7D).

       Logically, the  cvc driver sits below the  console driver. It redirects console output to the cvcredir(7D) driver if a network console con-
       nection is active. If a network console connection is not active, it redirects console output to an internal hardware interface.

       The cvc driver receives console input from  cvcredir and internal hardware and passes it to the process associated with /dev/console.

NOTES

       The   cvc facility supersedes the SunOS wscons(7D) facility, which should  not be used in conjunction with  cvc. The  wscons driver is use-
       ful for systems with directly attached consoles (frame buffers and keyboards), but is not useful with platforms using cvc,  which  have  no
       local keyboard or frame buffer.
