Enabling the suspension capability of a logical partition

You can enable the suspension capability of a logical partition by using the Hardware Management Console (HMC), after the logical partition is created.

To enable the suspension capability, ensure that an AIX® or Linux logical partition is either in the Not activated or Running states.

For an IBM® i logical partition, the partition must be in the shut down state.

While suspending a logical partition, the HMC stores the data about the switching mode in the reserved storage device that was used to store the configuration data.

To enable the suspension capability of a logical partition after the creation of the logical partition by using the HMC, follow these steps:

In the navigation pane, open Systems Management > Servers, and click the system on which the logical partition is located.
Select the logical partition in the work pane.
From the Tasks menu, select Properties.
- If Allow this partition to be suspended check box is selected, the logical partition is suspend-capable.
- If Allow this partition to be suspended check box is not selected, the logical partition is not suspend-capable. To enable the suspension capability of the logical partition, select the Allow this partition to be suspended check box.
  The HMC validates whether the logical partition is suitable for suspension by evaluating against all resource and configuration restrictions. If the validation succeeds, the logical partition is successfully enabled for suspension. If the validation fails, error messages are shown for your appropriate action.
Click OK.

When the logical partition is in the Running state, and when the partition is suspend-capable, you must not dynamically add restricted resources like dedicated I/O resources, Host Ethernet Adapter, or Host Connection Adapters to the suspend-capable logical partition.
