	Here we're using a block size of 8K and batch creating quantity 8x Storage Volumes from the pool each of 3TB in size. The size of each volume should be 1/8th of 95% of the usable capacity of the Storage Pool in order to give all the available usable storage to the IBM SVC. For example if your Storage Pool has 82TB of usable space then one could create 8x 10TB Storage Volumes to assign to the IBM SVC appliance.

			== Step 5: Enable Emulation Mode ==

			By default QuantaStor LUNs will not show up in the Mdevice scan from the IBM SVC. To address this we currently require the system to be put into an emulation mode. This can be enabled by running this command at the console/SSH as root on each QuantaStor system. Note a REBOOT IS REQUIRED after applying this change. After the reboot the Storage Volumes will present to the IBM SVC with "PURE" and "FlashArray" as the emulation mode by default.

			=== Emulation Mode for QuantaStor 5.12 and newer ===
			<pre>
			touch /var/opt/osnexus/quantastor/touchfiles/tf_wwnemulation.enable
			</pre>

			=== Emulation Mode for QuantaStor 5.11 and older ===
			<pre>
			printf "[defaults]\nvendor_id=PURE\nproduct_id=FlashArray\n" > /etc/qs_scst.conf
