⁠7.9. Configure ISO Domain

Now that you have configured your data storage domains, the next step is to define an ISO domain for your new data center. If you have an additional NFS mount point, you can choose to create a new ISO domain and attach it to your new data center. Alternatively, you can also use the local ISO domain created during the Manager installation. An ISO domain can be shared across data centers, even if the data center storage types are different.
⁠

Option 1: To create a new ISO domain

  1. On the side pane, select the Tree tab and click Expand All. Under the FinanceDataCenter data center, select Storage. On the results list, click New Domain.
  2. The New Storage dialog box displays. Configure the following options:
    1. Name: Enter iso-domain.
    2. Data Center: The FinanceDataCenter data center is already pre-selected.
    3. Domain Function / Storage Type: In the drop down menu, select Data → NFS. The storage domain types which are not compatible with the Default data center are grayed out. After you select your domain type, the Export Path field appears.
    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.
    5. Export Path: Enter the IP address or a resolvable hostname of the chosen host. The export path should be in the format of 192.168.0.10:/Images/NFS-Share or domain.example.com:/Images/NFS-Share.
  3. Click OK. The new iso-domain displays on the Storage tab. It displays with a Locked status as the domain is being validated before becoming Active.
You have now successfully defined an ISO domain for your new data center, and can now upload ISO images to it. Once you have populated your ISO domain, you can create virtual machines.
Alternatively, if you do not have an NFS mount point for a new ISO domain, use the local-iso-share domain which was created on the Manager server.

Option 2: To attach the existing ISO domain to a new data center

  1. On the side pane, select the Tree tab and click Expand All. Click FinanceDataCenter. On the results list, the FinanceDataCenter data center displays. Click on it to display the details pane.
  2. On the details pane, select the Storage tab and click the Attach ISO button. Select the local-iso-share domain and click OK.
  3. The ISO domain appears in the results list of the Storage tab. It displays with the Locked status as the domain is being validated, then transits to Inactive.
  4. Select the ISO domain and click the Activate button. The status changes to Locked and then to Active.
You have now successfully attached the ISO domain from the Manager server to your new data center. All the installation images which were available in the Default data center can now be used for the FinanceDataCenter data center. You can create more virtual machines on your new hosts. Just remember to substitute the default cluster for FinanceCluster and the default data center for FinanceDataCenter.
