This chapter describes how to perform system and frame management tasks. This chapter also includes information about system profiles.
You can perform the tasks discussed in this chapter when the managed system is selected in the Contents area. A managed system is shown below a "frame" in the Contents area. A frame manages a collection of managed systems.
The HMC communicates with the managed system to perform various system management, service, and partitioning functions. Systems connected to an HMC are recognized automatically by the HMC, and are then shown in the Contents area.
You can connect up to two HMCs to each managed system by using the serial cable that was provided with the HMC. You can also manage multiple systems with one HMC. For more information about using two HMC connected to one managed system, see Using Two HMCs Connected to One Managed System.
To view more information about the managed system, click on the Server Management icon in the Navigation area. The Contents area expands to show a frame, which you can then expand to show information about the managed system, including its name, its state, and the operator panel value.
To expand your view of the managed system's properties, click the plus sign (+) next to the managed system's name to view its contents.
In the Contents area, you can also select the managed system by right-clicking on the managed system icon to perform the following:
You can also access these options by clicking on the managed system and then clicking Selected on the menu.
You can use your HMC to power on the managed system.
To power on the managed system, you must be a member of one of the following roles:
To power on the managed system, do the following:
You are asked to select a power-on mode from the following:
The next section discusses each of these power-on modes.
The Partition Standby power-on option allows you to create and activate logical partitions. When the Partition Standby power-on is completed, the operator panel on the managed system displays LPAR..., indicating the managed system is ready for you to use the HMC to partition its resources.
For more information about partitions, see Partitioning.
The Full System Partition power-on option allows you to use all of the system's resources on one operating system after the system has been powered on. This is the traditional single-system method of using your system's resources.
The physical operator panel on your managed system displays progress codes when you boot the system to this mode.
If you select the Full System Partition option, you can then select one of the following profiles:
Using this profile to boot the system is the preferred way to run online diagnostics.
For more information about SMS menus, see the PCI Adapter Placement Reference, order number SA23-2504.
To learn more about these power-on options, see the service documentation for your managed system.
For more information about the Full System Partition, see Full System Partition.
The System Profile option powers on the system according to a predefined set of profiles.
You can also use your HMC to power off the managed system. Ensure that all partitions have been shut down and their states have changed from Running to Ready.
To shut down a partition, do the following:
To power off the managed system, you must be a member of one of the following roles:
To power off the managed system, do the following:
When you power off the managed system, each partition associated with that managed system also powers off.
To view your managed system's configuration and capabilities, use the properties window.
Any user can view managed system properties.
To view your managed system's properties, do the following:
If you have powered on your system using the Full System Partition option, the HMC displays the system's name, partition capability, state, serial number, model and type, and policy information. A system that is powered on using the Partition Standby option displays this information, as well as available and assigned processors, memory, I/O drawers and slots, and policy information. The Processor tab displays information that is helpful when performing Dynamic Logical Partitioning processor tasks.
Use the Processor tab to view the processor status, the processor state, and whether a processor is assigned to a partition. The information in the Processor tab is also helpful when you need to know if processors are disabled and therefore are not able to be used by any partition. For more information about recovering resources, see Appendix C, Error Messages and Recovery Information.
Use the Policy tab to perform the following tasks:
You can back up, restore, initialize, and remove profiles that you have created. This section describes each of these options.
To back up profile data, you must be a member of one of the following roles:
To back up profile data, do the following:
Selecting this menu item restores profile data to the system from the local file system.
To restore profile data, you must be a member of one of the following roles:
To restore profile data, do the following:
When you initialize profile data, you return the HMC to its original state. After you perform this task, any profiles that you created are erased.
To initialize profile data, you must be a member of one of the following roles:
To initialize profile data, do the following:
To remove stored profile data, you must be a member of one of the following roles:
To remove stored profile data, do the following:
If you no longer want to manage a particular system, you can delete it from the Contents area.
To delete the managed system from the Contents area, you must be a member of the System Administrator role.
To delete the managed system from the Contents area, do the following:
The managed system's icon is removed from the Contents area, and the connection is broken between the HMC and the managed system.
Rebuilding the managed system acts much like a refresh of the managed system information. Rebuilding the managed system is useful when the system's state indicator in the Contents area is shown as Recovery. The Recovery indicator signifies that the partition and profile data stored in the managed system must be refreshed.
This operation is different from performing a refresh of the local HMC panel. In this operation, the HMC reloads information stored on the managed system.
Any user can rebuild the managed system.
To rebuild the managed system, do the following:
After you select Rebuild Managed System, current system information displays.
Perform this task only if you have two HMCs connected to your managed system and one of the HMCs is not responding. For more information, see Releasing an HMC Lock on the Managed System.
The HMC enables the operating system on a partition to be reset when errors are encountered in the operating system. The system can undergo either a soft or hard reset, as follows:
For more information about configuring your operating system's policy settings, refer to your operating system documentation.
Attention: Issuing a hard reset forces termination and can corrupt information. Use this option only if the operating system is disrupted and cannot send or receive commands.
To reset the operating system, you must be a member of one of the following roles:
To reset the operating system on a partition, do the following:
A frame is a collection of managed systems and resources. Each frame is shown in the Contents area as the root of a resource tree; managed systems are listed underneath each frame.
Any user role can refresh a frame.
If a managed system that is part of a frame does not show up under the frame in the Contents area, you should refresh the frame as follows:
The Contents area is updated to show the latest frame information.
If your managed system is a frame housing multiple managed systems and resources, you can use your HMC to perform the following frame-management tasks:
If your managed system is not a frame housing multiple managed systems and resources, these tasks are not enabled. The only option available to you is to refresh the frame.
The frame must be manually powered on before its managed systems and other resources can be powered on.
Perform this task the first time that the frame is plugged into the wall, and whenever resources in a frame have been added, removed, or recabled.
To initialize a frame's managed systems and resources, you must be a member of one of the following roles:
To power on the managed resources in the frame, do the following:
The frame's properties panel shows you all of the managed systems and I/O drawers that exist in the frame.
To view frame properties, you must be a member of one of the following roles:
