3.5.2. 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. On the side pane, select the Tree tab. On System, click the + icon to display the available data centers.
  2. Double click on the Default data center and click on Storage. The available storage domains display on the results list. Click New Domain.
  3. The New Domain dialog box displays.
    Add iSCSI Storage
    Figure 3.13. Add iSCSI Storage

    Configure the following options:
    1. Name: Enter a suitably descriptive name.
    2. Data Center: The Default data center is already pre-selected.
    3. Domain Function / Storage Type: In the drop down menu, select DataiSCSI. The storage domain types which are not compatible with the Default data center are grayed out. After you select your domain type, the Use Host and Discover Targets fields display.
    4. Use host: Select any of the hosts from the drop down menu. Only hosts which belong in this data center will display in this list.
  4. To connect to the iSCSI target, click the Discover Targets bar. This expands the menu to display further connection information fields.
    Attach LUNs to iSCSI domain
    Figure 3.14. Attach LUNs to iSCSI domain

    Enter the required information:
    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.
  5. Click the Discover button to find the targets. The iSCSI targets display in the results list with a Login button for each target.
  6. Click Login to display the list of existing LUNs. Tick the Add LUN checkbox to use the selected LUN as the iSCSI data domain.
  7. Click OK. The new NFS 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 3.5.4, “Attach and Populate ISO domain”.
