The logical unit provider for creating disk-type LUs is called sbd. However, you must initialize the storage for the logical unit before you can share a disk-type LU.
The disk volume provided by the server is referred to as the target. When the LU is associated with an iSCSI target, it can be accessed by an iSCSI initiator.
The process for creating SCSI LUs is as follows:
Initialize the storage for the LU, also known as the backing store.
Create a SCSI LU by using the backing store.
When a LU is created, it is assigned a global unique identifier (GUID), for example, 600144F0B5418B0000004DDAC7C10001. The GUID is used to refer to the LU in subsequent tasks, such as mapping a LU to select hosts.
The following steps are completed on the system that is providing the storage device.
target# zpool create sanpool mirror c2t3d0 c2t4d0
target# zfs create -V 2g sanpool/vol1
target# stmfadm create-lu /dev/zvol/rdsk/sanpool/vol1 Logical unit created: 600144F0B5418B0000004DDAC7C10001
You can find the device path for the ZFS volume in the /dev/zvol/rdsk/pool-name/ directory.
target# stmfadm list-lu LU Name: 600144F0B5418B0000004DDAC7C10001
This command makes the LU accessible to all systems.
target# stmfadm add-view 600144F0B5418B0000004DDAC7C10001
If you want to restrict the LU view to specific systems, see How to Restrict Logical Unit Access to Selected Systems.
