Thaw a Domain

Use this procedure to thaw an I/O Domain that is frozen. This is performed when you want to take a domain from the Frozen state back to the Ready for Use state (with OS running).

  1. Access the SuperCluster Virtual Assistant.

    See Log In to the SuperCluster Virtual Assistant.

  2. In the navigation panel, select I/O Domains.
  3. Select the frozen I/O Domain.
  4. Click Thaw.

    The next screen enables you to choose a physical host for this I/O Domain. If you pinned an I/O domain to a host, the domain can only be thawed on that specific host. For more information, see Freeze a Domain.

    If the assistant detects that any auxiliary ISCSI LUNs are associated with the I/O Domain, the assistant includes that information in the screen, as shown below:

    This example shows the screen that is displayed when there are no auxiliary iSCSI LUNs associated with the I/O Domain.

  5. Select a physical host from the drop-down menu.

    Not all I/O domains can be thawed on all physical hosts for these reasons:

    • If you pinned an I/O Domain to a physical host, that domain can only be thawed on that specific physical host. For more information, see Freeze a Domain.

    • You can only thaw an I/O Domain on a physical host that has sufficient available resources to accommodate the frozen I/O Domain.

    • Some I/O Domains have auxiliary LUNs associated with them (for example, for zone file systems). These I/O Domains can only be thawed on physical hosts that have access to all auxiliary LUNS.

  6. Click Thaw.

    The process takes a few minutes to complete. Once complete, Ready for Use is displayed in the State column.


    Tip  -  Click the Refresh button to ensure that the page reflects the most current state.

    This example shows the state of the I/O Domain during the thaw process.
