Oracle® Enterprise Manager Ops Center

Adding Volumes to SAN Storage Libraries

12c Release 2 (12.2.2.0.0)

E58122-01

December 2014

This guide provides an end-to-end example for how to use Oracle Enterprise Manager Ops Center.

Introduction

A storage library can use block storage or file system storage. Block storage is backed by Fibre Channel disks or iSCSI disks in the form of Logical Units or LUNs. The LUNs store virtualization hosts' metadata and data and are assigned to storage libraries.

For LUNs backed by Fibre Channel disks, the block storage is static. From the user interface of Oracle Enterprise Manager Ops Center, you cannot change the size of the LUNs, delete them, or create new LUNs. However, you can add more LUNs to the library or remove LUNs if they are not in use. The number of LUNs in the storage library determines the number of virtual hosts that the library can support.

In this document, you use Oracle Enterprise Manager Ops Center to locate a specific LUN in one storage library and add it to an existing storage library.

What You Will Need

You will need the following to add LUNS to a guest's storage capacity:

SAN LUNs in an existing storage library.

Adding a LUN to a SAN Storage Library

These procedures demonstrate how to assign a set of LUNs to the storage capacity available to a guest.

In the Navigation pane, select Assets and then select a guest. In the example, g1 is selected. You could select the Add Storage action from the Action pane, but to see the guest's current storage capacity, click the Storage tab.

To add storage, select the Add Storage icon, which is highlighted in the Storage tab. This opens the Add Storage wizard.

In the Add Storage wizard, select the Add Multiple SAN LUNs icon, which is circled in the following example.

The Select SAN LUNs wizard has no content in its initial view.

In the SAN Library drop-down list, select a storage library. In the following example, the exported_iscsi library is selected. The selection populates the Available LUNs table with all the LUNs in the storage library.

The Available LUNs in library field shows that seven LUNs are available, all the same size.

To add storage to the guest, select one or more LUNs from the Available LUNs table, then click the right arrow button to assign them to the Selected LUNs table. As you assign LUNs, the counters for Available Number of LUNs and Available Storage decrease and the counters for Additional Storage and Additional Number of LUNs increase.

You have these options for selecting LUNs:
- Identify a LUN by its GUID and click it. You can also use select multiple LUNs.
- Enter text in the Search field to filter the list of LUNs to those GUIDs that match the text string. Click one or more LUNs.
- Select all of the LUNs. Select the double-right arrow button.
In this example, four LUNs are selected and then assigned as additional storage.

When the list of Selected LUNs is complete, click Finish. The Add Storage wizard shows the added LUNs.

You can continue to add LUNs from the same storage library or from another storage library. When you have added sufficient storage capacity, click the Finish button. The center pane is displayed.
Click the Refresh icon to show the new LUNs.

What's Next

The guest now has the added storage capacity to store its metadata and data.
