Enclosure tree object Creating logical devices

Complete the following steps to create logical devices:

  1. Click the appropriate Pool tab.

  2. Click .
  3. If you do not want to use the maximum size for the logical device, click the Size field; then, type the logical device size.

    Notes:
    1. Some operating systems have size limitations for logical devices. Before you save the configuration, verify that the size of the logical drive is appropriate for your operating system. For more detailed information, see your operating-system documentation.
    2. A logical device cannot exceed 256 terabytes (TB) (2 terabytes for HostRAID controllers); the minimum size is 10MB.
    3. Typically, the first logical device defined on the first controller found by system BIOS during startup will be your startup (boot) drive.
    4. The actual logical-drive size might be slightly different from what you select. The RAID level and the number of physical drives determine the size of the logical device. For example, a pool consisting of three, 1 GB physical drives with a requested RAID level-0 logical drive of 1000 MB will actually contain only 999 MB because the data is striped across all three drives, with 333 MB on each drive.
  4. Click the Name field; then, type the logical device name. The name must begin with an upper- or lower-case letter (a-z, A-Z).
  5. For iSCSI initiators only, define the authentication method for users of this logical device:
    1. From the Authentication drop-down list, choose the authentication method:
      • None - Do not authenticate users
      • CHAP - Challenge Handshake Authentication Protocol
      • SRP - Secure Remote Password
    2. For SRP authentication, choose the scope name: you can use the default name (DEFAULT); type a unique scope name in the Scope field; or choose an existing name from the drop-down list.
    3. For CHAP authentication, click ; the "Global user name and password management" window opens. Then, add users to the user list.
  6. If you have free space in the pool and want to create additional logical devices, click ; then, repeat steps 3-5. To create a new logical device with the same settings as the current logical device, click .


    Note: As you create each logical device, the cylinder view on the right shows used and free space.

  7. Repeat steps 1-6 for each additional pool that you want to configure.
  8. Click Next. The "Assign logical devices to initiators" window opens.

To leave the Configuration wizard, click Cancel.
