Before you configure Solaris I/O multipathing features, consider the following:
Configure ports and zones according to the vendor-specific documentation for storage and switches.
LUN masking enables specific LUNs to be seen by specific hosts. See your vendor-specific storage documentation that describes masking.
Power management needs to be disabled for hosts and devices on a SAN. For more information about power management, see poweradm (1M) .
The STMS boot utility is included with Solaris I/O multipathing features that manage the SAN booting process. Issuing the stmsboot command automatically updates the /etc/vfstab file 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.
Fabric-connected devices are configured and made available to the host automatically during installation and boot time.
