Chapter 4. Implementing the SAN Data Gateway 303
Setting up a Virtual Private SAN
Remember that the SAN Data Gateway assigns its own LUN numbers, and it
does so in a sequential order. An attached disk device may have a SCSI target of
1 with a LUN ID of 4, but when recognized by the SAN Data Gateway, its LUN
number assigned will be something completely different. An example is shown in
Figure 4-36.
Figure 4-36 SCSI LUN assignment
In this example, the disk device attached has a SCSI target of 6 and LUN ID of 1.
When it was recognized by the SAN Data Gateway, the Gateway assigned LUN
number 38 to this device. This Gateway’s assigned LUN number corresponds to
the assigned LUN number that appears on the top of the VPS settings window,
as shown Figure 4-38 on page 305.
