This set of changes is for scsi pools that are based on a host bus adapter. These types
of sotrage include FiberChannel attached storage devices, as well as
SANs. There's two different ways to define these pools:
FiberChannel connected devices:
<pool type="scsi">
<name>hba0</name>
<source>
<adapter name="host4"/>
</source>
<target>
<path>/dev/disk/by-id</path>
</target>
</pool>
SAN devices:
<pool type="scsi">
<name>npiv</name>
<source>
<adapter name="host6" wwpn="0000111122223333"
wwnn="4444555566667777"/>
</source>
<target>
<path>/dev/disk/by-id</path>
</target>
</pool>
