How to Use a ZFS Volume as an iSCSI LUN

1. First, install the COMSTAR package.

   $ pkg install group/feature/storage-server
   

2. Create a ZFS volume to be used as an iSCSI target.

   For example:

   $ zfs create -V 2g system1/volumes/v2
   

3. Create the SCSI-block-device-based LUN.

   For example:

   $ sbdadm create-lu /dev/zvol/rdsk/system1/volumes/v2
   Created the following LU:
   
   GUID                    DATA SIZE           SOURCE
   --------------------------------  -------------------  ----------------
   600144f000144f1dafaa4c0faff20001  2147483648           /dev/zvol/rdsk/system1/volumes/v2
   $ sbdadm list-lu
   Found 1 LU(s)
   
   GUID                    DATA SIZE           SOURCE
   --------------------------------  -------------------  ----------------
   600144f000144f1dafaa4c0faff20001  2147483648           /dev/zvol/rdsk/system1/volumes/v2

4. Share LUN views to all ZFS clients. or selected ZFS clients.

   You can expose the LUN views to all ZFS clients or to a selected list of ZFS clients. In the following example, the LUN view is shared to all ZFS clients.

   1. Identify the LUN GUID.

      $ stmfadm list-lu
      LU Name: 600144F000144F1DAFAA4C0FAFF20001

   2. Share the LUN view.

      $ stmfadm add-view 600144F000144F1DAFAA4C0FAFF20001
      $ stmfadm list-view -l 600144F000144F1DAFAA4C0FAFF20001
      View Entry: 0
      Host group   : All
      Target group : All
      LUN          : 0

5. Create the iSCSI targets.
