Adding LUNs

When to add LUNs

You add LUNs (called volumes on the IBM storage subsystem UI) for your gateway after you create the dummy host on the storage subsystem. You can use the dummy host to create more LUNs for your gateway.

To map LUNs to the actual gFiler gateway, follow the procedure described in Chapter 4, Modifying LUNs on your storage subsystem.

Caution
You must always add LUNs to the dummy host. The gFiler gateway cannot recognize LUNs while they are being formatted by the storage subsystem. Adding LUNs to the actual gFiler gateway using the Add Volumes option can cause data corruption.

Adding LUNs

To add LUNs on your storage subsystem, complete the following steps.

Note
The term volume is used to mean LUN in the following procedure.

Step	Action
1	Go to the Open Systems Storage screen.
2	Click Add Volumes on the Open Systems Storage screen.
3	Select the dummy host and the cluster on which your gateway connects to your storage system by clicking the appropriate icons, as shown in the figure.
4	When you complete this stage, click Next at the bottom of the screen.
5	Select the Volume Size from the Volume Attributes scrolling list and determine the number of volumes desired at that size, as shown in the figure.
6	When you finish selecting the attributes of the volume you are creating, click Add, which is between the Volume Attributes list and New Volumes list, as shown in the figure.
7	When you finish configuring the volumes, click Perform Configuration Update at the bottom of the screen. Note This task can take up to several hours to complete.
