clprivnet - SUNW,clprivnet Sun Cluster private network driver
Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-ori-
ented command set. Although Sun Cluster software still supports the original command
set, Sun Cluster procedural documentation uses only the object-oriented command set. For
more information about the object-oriented command set, see the Intro(1CL) man page.
The SUNW,clprivnet Sun Cluster private network driver is a STREAMS pseudo driver support-
ing Sun Cluster resident applications that use standard Solaris interfaces to communicate
over the Sun Cluster private network. By striping data traffic over all links, this driver
optimally utilizes the bandwidth of the private network while supporting highly available,
software fault-tolerant communication.
APPLICATION PROGRAMMING INTERFACE
The driver is supported by the character-special device /dev/clprivnet, but is reserved
for Sun Cluster internal operation and the standard Solaris network utilities. This inter-
face must not be directly used for general application communication.
The administration and configuration of the driver as a network interface is done com-
pletely by the Sun Cluster infrastructure internals.
