Configuration Considerations

Before you configure the Sun StorageTek Traffic Manager software, 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. See power.conf (4) for details about power management.

• The STMS Boot utility is included with the Sun StorageTek Traffic Manager software that manages the enable and disable process needed for SAN booting. 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 Sun StorageTek Traffic Manager software. Note that the software is disabled by default with SPARC devices and enabled by default with x86 devices.

• For Sun Solaris Express Developer's Edition OS, fabric-connected devices are configured and made available to the host automatically during install and boot time.

  Note –

  If you are performing an upgrade and want to make any Fibre Channel (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 fabric-connected devices has been turned on. To find out how to disable the fabric devices discovery during boot or install, please refer to Appendix A, Manual Configuration for Fabric-Connected Devices
