SAN Device Considerations

Be aware of the following considerations before configuring the Sun StorageTek Traffic Manager software.

• Configure ports and zones according to the vendor-specific documentation for storage and switches.

• With the Solaris 10 OS you no longer have to manually configure devices unless you enable manual device configuration.

• LUN masking enables specific LUNs to be seen by specific hosts. See your vendor-specific storage documentation that describes masking.

• 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. See power.conf(1M) man page for details about power management.

• Connect arrays and other storage devices to the SAN with or without multipathing capability. The Sun StorageTek Traffic Manager software is an associated application that is bundled with the product name.

• 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.
