Create a New Pool

When you create a pool, XenCenter® attempts to resolve any pool configuration issues before creating the pool.

There might be other hardware or configuration issues that prevent a server from successfully joining a pool. For more information, see Pool requirements.

To create a pool

  1. Open the New Pool wizard by clicking New Pool on the Toolbar.
  2. Enter a name for the new pool and an optional description. The name is displayed in the Resources pane. Click Next.
  3. Nominate the pool coordinator by selecting a server from the Coordinator list.

  4. Select more servers to place in the new pool from the Additional members list. All available managed servers are listed. If a server is not listed, you can add it to the list by clicking Add New Server. If a managed server does not satisfy one or more of the pool join requirements listed in Pool requirements, it appears disabled.

    Click Next.

  5. On the Pre-checks panel, XenCenter identifies any pool configuration issues that might need to be resolved:

    • The supporting servers must be licensed at the same level as the pool coordinator.

      • If the supporting server does not have a license and the pool coordinator has licenses available on the connected License Server, XenCenter automatically applies the appropriate license.

      • If the supporting server has a different license to the pool coordinator, this server shows as disabled in the Additional members list. You cannot add the server to the pool.

      You can change the license of any pool members after joining the pool. The server with the lowest license determines the features available to all members in the pool. For more information about licensing, see About XenServer Licensing.

    • The supporting servers must be part of the same Active Directory domain as the pool coordinator.

      • If the pool coordinator is joined to a domain and the supporting server is not joined to a domain, XenCenter automatically joins the supporting server to the same domain.

        At the Create Pool step, you are prompted for credentials on the supporting server. Enter your AD credentials for the domain to which the pool is joined. These credentials must have sufficient privileges to add servers to the domain.

      • If the pool coordinator is joined to a domain and the supporting server is joined to a different domain, this server shows as disabled in the Additional members list. You cannot add the server to the pool.

    • The supporting server must be at the same level of updates as the pool coordinator. If the supporting server is at an earlier level of updates than the pool, XenCenter synchronizes it with the pool coordinator and applies updates from the pool coordinator to the supporting host.

    Click Next to attempt to resolve these pre-checks and create the pool.

  6. On the Create Pool panel, XenCenter resolves the pool configuration issues, creates the pool, and displays the results. Click Finish to close the wizard.

If the pool coordinator already has a shared storage repository (SR), this repository becomes a shared SR for the pool. If the new pool coordinator does not have any shared storage, you have to create a new shared SR for the pool. For more information, see Creating a New SR.

More pool configuration steps

To configure the new pool, use the property tabs:

  1. To add shared storage to the pool, see Creating a New SR.
  2. To add more servers to the pool, see Add a Server to a Pool.
