SNIA Multipath Management API support

This system administration feature is new in the Solaris Express 5/06 Release.

The Storage Networking Industry Association (SNIA) Multipath Management API (MP API) defines standard interfaces for multipath devices, associated path discovery, and path administration on a host. This feature provides Sun's implementation of the SNIA MP API library for the scsi_vhci driver-based multipathing solution.

The SNIA MA API consists of the following components:

• /usr/sbin/mpathadm CLI

• /lib/libMPAPI.so common library

• /lib/libmpscsi_vhci.so plug-in for the scsi_vhci driver

The following areas have been extended to support the SNIA MP API feature:

• MDI

• SCSA

• libdevinfo

• scsi_vhci IOCTL

With this feature, the administrators can use the standards-based path administration for scsi_vhci multipath devices.

For more information see the mpathadm(1M) and libMPAPI(3LIB) man pages. See also the Solaris Fibre Channel Storage Configuration and Multipathing Support Guide.
