Creating an online LUSE volume for Windows

Open-Systems Host Attachment Guide

Part Number

This section explains how to safely expand an online LUSE volume in the Windows operating system.

  • It is recommended that you stop all I/O activity before you perform an online LUSE expansion.
  • Data migration is not needed for OPEN V (required for other LU types). A host reboot is not required for Windows. For more information, contact your Hitachi Vantara representative.

The following information applies to the instructions below:

  • LDEV # = 0:32
  • Mount point = i
  • capacity = 40 MB
  1. On the Windows host, confirm that Disk I is mounted and Disk 12 (the disk to be expanded) is on this system: Open Windows Computer Management, expand Storage, and select Disk Management.
  2. View the disk properties (right-click on the disk and select Properties) to get detailed information. In this example, details for Disk 13 are displayed.
  3. Create a LUSE volume. For instructions, see the Provisioning Guide for the storage system. After creating the LUSE volume, you can configure the Windows host to recognize the expanded LDEV (for example, using DISKPART).
  4. Return to the Windows Computer Management application, and refresh the display: Select Action > Rescan.

    When the rescan has completed, he mounted volume I:\ (disk 12) is expanded from 40 MB to 80 MB, but the newly added disk is not yet formatted. You must now combine the new partition (for example, using DISKPART).

    Note: Before using DISKPART, read all applicable instructions.
  5. At a command prompt, enter Diskpart, and press Enter.
  6. At the DISKPART> prompt, enter list disk, and press Enter.
  7. In the list of disks, when you have identified the disk to be expanded (Disk 1 in this example), enter select disk=1 (for this example), and press Enter. Disk 1 is now the selected disk on which the operations will be performed.
  8. At the DISKPART> prompt enter detail disk, and press Enter.
  9. After viewing the disk details, select the volume to be used. For this example, enter select volume = 4, and press Enter.
  10. At the DISKPART> prompt, enter extend, and press Enter to combine the available volumes for the selected disk into a single partition.
  11. Enter detail disk at the DISKPART> prompt, and press Enter to verify that the size is 68G.
