Storage Manager for SANs includes the Provision Storage Wizard, which you can use to create a logical unit number (LUN) on a Fibre Channel or iSCSI disk storage subsystem.

Before you create a LUN on a storage subsystem, verify that all the following requirements are fulfilled:

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at

To create a LUN
  1. In the console tree, click LUN Management.

  2. In the Actions pane, click Create LUN.

  3. Follow the steps in the Provision Storage Wizard pages.

Additional considerations

  • If you create a LUN and do not choose to create a volume for it immediately (by using the Provision Storage Wizard), the disk associated with that LUN will be visible to the server that you assign it to, but it will be offline. Before you can create a partition or volume on that disk, you must first use Disk Management or DiskPart to bring the disk online. For more information about bringing a disk online, see:

  • The types of LUNs that you can create depend on the types of LUNs that are supported by each of your storage subsystems. For more information about LUN types, see Overview of LUN Types.

  • The LUN creation process may take several minutes or longer to complete, depending on the properties that you selected and the subsystem hardware.
