clprivnet - SUNW,clprivnet Oracle Solaris Cluster private network driver




Note - Oracle Solaris Cluster software includes an object-oriented command set. Although Oracle Solaris Cluster software still supports the original command set, Oracle Solaris Cluster procedural documentation uses only the object-oriented command set. For more information about the object-oriented command set, see the Intro(8CL) man page.

The SUNW,clprivnet Oracle Solaris Cluster private network driver is a STREAMS pseudo driver supporting Oracle Solaris Cluster resident applications that use standard Solaris interfaces to communicate over the Oracle Solaris 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.


The driver is supported by the character-special device /dev/clprivnet , but is reserved for Oracle Solaris Cluster internal operation and the standard Solaris network utilities. This device interface must not be directly used for general application communication.


The administration and configuration of the driver as a network interface is done completely by the Oracle Solaris Cluster infrastructure internals.
