Restart
Restart the selected logical partition or partitions.
For IBM® i logical partitions, use this window only if you cannot restart the IBM i logical partition from the command line of the operating system. Using this window to restart an IBM i logical partition will result in an abnormal IPL.
If you choose to restart VIOS partitions that are acting as the Paging Service Partition (PSP) for a number of client partitions, a warning displays, indicating that you should shut down the client partitions before shutting down the VIOS partition.
Choose one of the following options. The Operating System option
and the Operating System Immediate option are enabled only if Resource
Monitoring and Control (RMC) is up and configured.
- Dump
- The HMC shuts down the logical partition and initiates a main storage or system memory dump. For AIX® and Linux logical partitions, the HMC also notifies the logical partition that it will be shut down. For IBM i logical partitions, the processors are stopped immediately. After the shutdown is complete, the logical partition is immediately restarted. (IBM i logical partitions are restarted multiple times so that the logical partition can store the dump information.) Use this option if a portion of the operation system appears hung and you want a dump of the logical partition for analysis.
- Operating System
- The HMC shuts down the logical partition normally by issuing a shutdown -r command to the logical partition. During this operation, the logical partition performs any necessary shutdown activities. After the shutdown is complete, the logical partition is immediately restarted. This option is only available for AIX logical partitions. Immediate: The HMC shuts down the logical partition immediately. The HMC ends all active jobs immediately. The programs running in those jobs are not allowed to perform any job cleanup. This option might cause undesirable results if data has been partially updated. Use this option only after a controlled end has been unsuccessfully attempted.
- Operating System Immediate
- The HMC shuts down the logical partition immediately by issuing a shutdown -Fr command to the logical partition. During this operation, the logical partition bypasses messages to other users and other shutdown activities. After the shutdown is complete, the logical partition is immediately restarted. This option is only available for AIX logical partitions.
- Dump Retry
- The HMC retries a main storage or system memory dump on the logical partition. After this is complete, the logical partition is shut down and restarted. Use this option only if you have previously tried the Dump option without success. This option is only available for IBM i logical partitions.
