How to Create SCSI Logical Units
The logical unit provider for creating disk-type logical units is called sbd. However, you have to initialize the storage for the logical unit before you can export a disk-type logical unit.
The process for creating SCSI logical units is as follows:
- Initialize the storage for the logical unit, also known as the backing store.
- Create a SCSI logical unit using the backing store.
When the logical unit is created it is assigned a global unique identifier (GUID), for example, 6000ae4000144f972b2e486291410001. The GUID is used in subsequent tasks to refer to the logical unit, such as mapping a logical unit to select hosts.
You can create a SCSI logical unit in the following ways:
- How to Create a File-Based SCSI Logical Unit
- How to Create a Thin-Provisioned SCSI Logical Unit
- How to Create a Disk Partition SCSI Logical Unit
- How to Create a ZFS Volume SCSI Logical Unit
 | Important Note Determine which backing store is best suited for the available capacity on the SCSI target. Consider the amount of data you plan to store, data retrieval needs, and required retrieval speed when making your decision. |
