DESCRIPTION

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

31       The DR driver provides a pseudo-driver interface to sequence attach and
32       detach operations on system  boards  using  file  system  entry  points
33       referred  to  as "attachment points." The attachment point form depends
34       on the platform.
35
36   Sun Enterprise 10000 Server
37       On the Sun Enterprise 10000 server, the DR driver consists of  a  plat‐
38       form-independent  driver  (ngdr)  and a platform-specific module (ngdr‐
39       mach).
40
41
42       The domain configuration server (DCS) accepts DR requests from the sys‐
43       tem  services processor (SSP) and uses the libcfgadm(3LIB) interface to
44       initiate the DR  operation.  After  the  operation  is  performed,  the
45       results  are returned to the SSP. For more information about the DCS on
46       the Sun Enterprise 10000, refer to the dcs(1M) man  page  and  the  Sun
47       Enterprise 10000 Dynamic Reconfiguration User Guide.

49
50       The DR driver creates physical attachment points for system board slots
51       that takes the following form:
52
53         /devices/pseudo/ngdr@0:SBx
54
55
56
57       Where x represents the slot number (0 to 15) for a particular board.
58
59
60       The cfgadm_sbd(1M) plugin creates dynamic attachment points that  refer
61       to components on system boards, including CPUs, memory, or I/O devices.
62       Refer to the cfgadm_sbd(1M) man page for more details.
