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.
