|Oracle Solaris SAN Configuration and Multipathing Guide Oracle Solaris 10 1/13 Information Library|
Review the following considerations before configuring Solaris I/O multipathing features:
Configure ports and zones according to the vendor-specific documentation for storage and switches.
You no longer are required to manually configure devices.
Turn off power management on servers connected to the SAN to prevent unexpected results as one server attempts to power down a device while another attempts to gain access.For more information about power management, see power.conf(4).
Connect arrays and other storage devices to the SAN with or without multipathing capability. Solaris multipathing is an associated application that is bundled with the product name.
The STMS boot utility is included with Solaris I/O multipathing features that manage the SAN booting process. Issuing the stmsboot command activates the automatic update of /etc/vfstab and the dump configuration to reflect device name changes when enabling or disabling the multipathing software. Note that the software is disabled by default for devices on SPARC based systems and enabled by default for devices on x86 based systems.
