A. Manual Configuration for Fabric-Connected Devices
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 allows 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 SPARC devices and enabled by default with x86 devices.
Fabric-connected devices are configured and made available to the host automatically during installation and boot time.
Note - If you are performing an upgrade and want to make any FC devices unavailable after upgrade, those devices have to be manually unconfigured using cfgadm -c unconfigure commands. However, to make those devices permanently unavailable to the system, you may want to consider using switch zoning or LUN masking. The changes made by cfgadm -c unconfigure do not persist after a reboot unless manual configuration for FC devices has been enabled. To find out how to disable the FC devices discovery during boot or install, please refer to Appendix A, Manual Configuration for Fabric-Connected Devices.
