Configure Libraries for Use with RAID 1

You can use the Virtual Library configuration tool to configure your library into smaller libraries that you can use for RAID Level 1 Mirroring. You can set up RAID 1 Mirrors on either two drive libraries or a single drive library.

Note: You must install the Arcserve Backup Tape RAID Option to set up and use RAID Level 1 Mirroring.

To configure a multi-drive library into Virtual Libraries to be used in a RAID configuration, perform the following procedure:

  1. Start Device Configuration.
  2. When the Options screen appears, select Virtual Library and click Next.
  3. A message appears notifying you that the Tape Engine will be stopped. Click OK to continue.
  4. Select the multi-drive library you want to use and click New.
  5. Select the drives and slots that you want to add to the Virtual Library and click OK.

    Note: Only two drives are supported when adding a Virtual Library to a RAID Level 1 Mirror.

  6. (Optional) Repeat steps 5 and 6 to create as many two drive libraries as you have available, or create a second Virtual Library using however many drives and slots remain.

    Note: When configuring the last of the drives, you must use all of the remaining slots. The Virtual Library configuration utility does not allow partial configuration or orphan slots.

  7. After you finish creating Virtual Libraries and the Virtual Library Configuration reappears, click Finish to save your settings and exit the configuration tool.
  8. Open Device Configuration, select Windows Server, and click Next again to configure RAID for your new Virtual Libraries.
  9. Select RAID Device and click Next.
  10. To create a RAID Level 1 Mirroring group, click New, and then enter the RAID Type and click OK. Highlight the Virtual Library that you want to add to the RAID group and click Assign.

    Note: You can repeat this step for each two-drive Virtual Library you created.

    The two-drive Virtual Library appears in the RAID Devices box on the left side of the screen and is assigned to the RAID Level 1 Mirroring group.
