Remote restart states

A simplified remote restartable partition goes through several state changes regarding the simplified remote restart operation, both on the source and destination servers. Most of the simplified remote restart operations are supported only when the partition is in the appropriate remote restart state. A remote restart state is not related to the logical partition state, but is an indicator that is specifically associated with the simplified remote restart operation.

You can use the lssyscfg command to view the remote restart status of the partition. The following are the possible values:

Invalid: The partition that is configured for simplified remote restart is in the Invalid state until the logical partition is activated. Simplified remote restart is supported only on a logical partition that has been started at least once.

Remote Restartable: After the partition is started and running, the partition transitions into the Remote Restartable state. A partition in this state can be remote restarted.

Source Remote Restarting: During the actual simplified remote restart operation, the source partition is in the Source Remote Restarting state. This state is transitional and valid until the simplified remote restart operation completes or the operation is canceled.

Destination Remote Restarting: During the actual simplified remote restart operation, the destination partition transitions into the Destination Remote Restarting state. This state is transitional and is valid until the simplified remote restart operation completes or the operation is canceled.

Destination Remote Restarted: When the simplified remote restart operation reaches the no return point on the destination system (all the adapters are configured on the destination system), the remote restart status is set to Destination Remote Restarted.

Remote Restarted: After the simplified remote restart operation completes, the source logical partition is in the Remote Restarted state. The source logical partition can be cleaned up and the destination logical partition is now again ready to be restarted as needed.

Local Storage Update Failed: When an update to persisted information (configuration data stored external to the server on persistent storage) on the Hardware Management Console (HMC) fails due to any reason, the logical partition is in the Local Storage Update Failed state. This state indicates that the persisted information on the HMC is out of synchronization with the current logical partition configuration. Simplified remote restart is not allowed in this remote restart state. However, you can use the usecurrdata option with the rrstartlpar command to run a simplified remote restart operation.

Forced Source Side Restart: When you use the usecurrdata option with the rrstartlpar command to run a simplified remote restart operation, the partition is restarted with the configuration data on the device and the remote restart state on the source system is updated to Forced Source Side Restart state.

Partial Update: When a system is connected to an HMC that has logical partitions with the simplified remote restart capability enabled, the HMC automatically collects the configuration information and the data is stored external to the server on persistent storage. Some configuration information like virtual adapter information, requires a Resource Monitoring and Control (RMC) connection to the Virtual I/O Server (VIOS) partitions. Therefore, the HMC waits until the RMC connection is established to collect such information. When the virtual adapter information is not collected for any reason, the remote restart state is set to Partial Update.

Stale Data: When a system is connected to an HMC, the remote restart state is set to Stale Data if there is configuration information existing for a logical partition before the state is changed to Partial Update. Simplified remote restart is not allowed in this remote restart state. However, you can use the usecurrdata option with the rrstartlpar command to run a simplified remote restart operation.

Out Of Space: When an update to the persisted information fails because there is insufficient space on storage disk of the HMC to store the configuration information, the remote restart state is updated to Out Of Space. You can free up space on storage disk of the HMC and run the refdev command to recover from this state.

Profile Restored: When a profile restore operation is performed on a system, during the creation of the simplified remote restart capable partition, the remote restart state is set to Profile Restored.

Source Side Cleanup Failed: When a cleanup operation performed on the source system after a successful simplified remote restart fails, remote restart state on the source partition is set to Source Side Cleanup Failed.

Reserved Storage Device Update Failed: This state is specific to the simplified remote restart operation that requires a reserved storage device. When an update to the reserved storage device fails for any reason, the logical partition is in the Reserved Storage Device Update Failed state. This state indicates that the data on the device is not synchronized with the current partition configuration. Simplified remote restart is not allowed in this remote restart state. However, you can use the -force option to run a simplified remote restart operation.
