You want to create a new LUN, LUN ID =1, on a new target, target ID = 2.
Inspect the current state of targets and LUNs in the output from tgt-admin -s. The output is filtered
to show only target and LUN associations.
[root@EDFAR9P0 init.d]# tgt-admin -s | egrep -i 'target|lun'
Target 1: iqn.2013-03.com.example.mypc:1
LUN information:
LUN: 0
LUN: 1
LUN: 2
LUN: 3
You want to add a new LUN to a new target by using the /iSCSIsharedDisk/physDisk4.img disk image file.
Which two options would you use to do this?

• A.tgt-setup-lun -d /iSCSIsharedDisk/physDisk4.img -n 2
• B.tgt-admin -d /iSCSIsharedDisk/physDisk4.img -n 2
• C.tgt-admin --op new \
  --mode target \
  --tid 2\
  --targetname iqn.2013-03.com.example.mypc:2
  tgt-admin --op new \
  --mode logicalunit \
  --tid 2 \
  --lun 1 \
  --backing-store /iSCSIsharedDisk/physDisk4.img
• D.tgtadm -- op new \
  --mode target \
  --tid 2\
  --targetname iqn.2013-03.com.example.mypc:2 \
  --lun 1 \
  --backing-store /iSCSIsharedDisk/physDisk4.img
• E.tgt-setup-lun -t 2
  tgt-setup-lun -d /iSCSIsharedDisk/physDisk4.img -t 2

• C.Blocks are automatically rebalanced across all existing devices after adding new devices.

Examine the virt-install command.
# virt-install \
--connect qemu:///system \
--virt-type kvm \

--disk path =/var/lib/libvirt/images/test.img, size=4
--cdrom /home/user01/DownLoads/OracleLinux-R6-U5-Server-x86_64-dvd.iso \
--os-variant oe16
