Remote STREAMS Environment
7-2 Fault Tolerant System Administration (R1004H) HP-UX version 11.00.03
STREAMS driver instance and a remote communications adapter STREAMS
instance from the file /etc/orse/orsdinfo.
NOTE
Prior to running an RSE application, first ensure that information in the
orsdinfo file is current, then run the otelrsd utility.
Figure 7-1 illustrates a configuration with four remote Streams. The first two
remote communications adapter Streams use one instance each of an operating
system host remote STREAMS driver (OHRSD) to pass messages through the PCI
bus and communications adapter. The third U916 PCI adapter has two Streams
open to it. Using information in orsdinfo, otelrsd sets up mapping between an
operating system kernel device and an RSE device.
