What is Multiplexed I/O (MPXIO) and how is it controlled?


Solution




MPXIO is SUN's version of Dynamic Multi-pathing (DMP).  

It is part of the SAN Foundation Kit on versions earlier than Solaris 10.  On Solaris 10 it is included.

It is controlled by the file /kernel/drv/scsi_vhci.conf.  The file has documentation on how to enable and disable the MPXIO as well as configure it for specific devices.

To disable MPXIO ensure that the mpxio-disable="yes"; is in the scsi_vhci.conf file.
