reconfiguration driver
SYNOPSIS
dr

ngdrmach
DESCRIPTION
The dynamic reconfiguration (DR) driver consists of a
platform-independent driver and a platform-specific module.
The DR driver uses standard features of the Solaris operat-
ing environment whenever possible to control DR operations and calls the platform specific module as needed. The DRdriver 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 ServerOn the Sun Enterprise 10000 server, the DR driver consists
of a platform-independent driver (ngdr) and a platform-
specific module (ngdrmach).
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 particu-
lar 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.SEE ALSO
