Creating iSCSI LUN Visible by Selected Node.

(VERSION INFORMATION: Solaris 11.1)


This restrict selected targets visible to initiator i.e. host group and selected LUN for particular target.
This is one of the best practice when provision LUN.

• 1. Create ZFS pool.

zpool create db-pool c0t600A0B800056405E0000621E530C68E7d0
zpool add -f db-pool c0t600A0B800056405E000049EF5253ECF4d0

• 2. create zfs disk/volume

zfs create -V 4g db-pool/dbvot1

• 3. Make ZFS volume LUN

stmfadm create-lu /dev/zvol/rdsk/db-pool/dbvot1

• 4. Enable scsi initiator (on all the isci client node)

svcadm enable network/iscsi/initiator
svcs -l iscsi/initiator ##check

• 5. iscsiadm list initiator-node [all client node]

The highlighted section will be used in the next command. Sample principle apply for FC WWN.

• 6. stmfadm create-hg host-db #[iscsi server node]
• 7. stmfadm add-hg-member -g host-db iqn.1986-03.com.sun:01:00144ffba06e.535be0bb iqn.1986-03.com.sun:01:00144ff99ca4.535be0e7

• 8. stmfadm create-tg target-racdb00

Create target group

• 9. Create the iSCSI

#itadm create-target

• 10. itadm list-target –v

• 11. PrimayNode #stmfadm offline-target iqn.1986-03.com.sun:02:315667dd-969a-e405-f715-c6d61ace3acb

Need to make target offline, if it online. See screenshot above.

• 12. PrimayNode #stmfadm add-tg-member -g target-racdb00 iqn.1986-03.com.sun:02:315667dd-969a-e405-f715-c6d61ace3acb

Add “iscsi target” to the target group

• 13. PrimayNode #stmfadm list-lu –v

Check available iSCSI LUN.


Can you create ZFS iSCSI

SCSI LUN created in step 1 to 3.

• 14. PrimayNode # stmfadm add-view -h host-db -t target-racdb00 -n 10 600144F000212834D270536B68270002

Adding LUN to host group and target group.

• 15. PrimaryNode #stmfadm list-view -l 600144F000212834D270536B68270002

• 16. Bring logical unit online.

PrimaryNode #stmfadm online-target iqn.1986-03.com.sun:02:315667dd-969a-e405-f715-c6d61ace3acb

• 17. Activate client’s initiator

root@dbnode1:~# iscsiadm list discovery
root@dbnode1:~# iscsiadm modify discovery -t enable

• 18. Add iSCSI address and port(default is 3260)

root@dbnode1:~# iscsiadm add discovery-address 192.168.200.21:3260

• 19. root@dbnode1:~# iscsiadm list target

• 20. Dynamically update /dev and /devices.

root@dbnode1:~# devfsadm –v

• 21. root@dbnode1:~# format

Other Cheat Commands:

• 1. delete logical unit view

stmfadm remove-view -l 600144F000212834D270536B68270002 0

• 2. stmfadm à SCSI Target Mode Framework
