6.2. Create an iSCSI Data Domain

Because you have selected iSCSI as your default storage type during the Manager installation, you will now create an iSCSI storage domain. Red Hat Enterprise Virtualization platform supports iSCSI storage domains spanning multiple pre-defined Logical Unit Numbers (LUNs).
To add iSCSI storage
  1. Navigate to the Tree pane and click the Expand All button. Under System, select the Default data center and click on Storage. The available storage domains display on the results list. Click New Domain.
  2. The New Domain dialog box displays.
    Add iSCSI Storage

    Configure the following options:
    1. Name: Enter ISCSI-share.
    2. Data Center: The Default data center is already pre-selected.
    3. Domain Function / Storage Type: The Data/ iSCSI option is already pre-selected because during installation you set iSCSI as your data center's default storage type. The storage domain types which are not compatible with the Data Center will not be available.
    4. Use Host: Select any of the available hosts from the drop down menu. Only hosts which belong in this data center will display in this list.
  3. To connect to the iSCSI target, enter the required information under the Discover Targets bar.
    Discover iSCSI target
    Figure 15. Discover iSCSI target

    1. Address: Enter the address of the iSCSI target.
    2. Port: Select the port to connect to. The default is 3260.
    3. User Authentication: If required, enter the username and password.
    Click the Discover button to find the targets. The iSCSI targets display in the results list with a Login button for each target.
  4. Click Login on the first target to display the list of existing LUNs. Click the + icon under the Target Name to expand the LUN list. Tick the Add LUN checkbox to use the selected LUN as the iSCSI data domain.

  5. Click OK. The new iSCSI-share data domain displays on the Storage tab. It will remain with a Locked status while it is being prepared for use. When ready, it is automatically attached to the data center.
You have created an iSCSI storage domain. Now, you need to attach an ISO domain to the data center and upload installation images so you can use them to create virtual machines. Proceed to Section 7, “Attach and Populate ISO Domain”.
