Restarting Linux logical partitions

You can restart Linux® logical partitions or the Linux operating system using the Hardware Management Console (HMC). Restarting a logical partition shuts the logical partition down and then starts it again.

To restart a Linux logical partition, complete the following steps from the HMC:
  1. In the navigation pane, expand Systems Management > Servers.
  2. Click the managed system on which the logical partition is located.
  3. In the work pane, select the logical partition.
  4. From the Tasks menu, click Operations > Restart.
  5. Select one of the following options:
    Option Description
    Operating System The HMC issues the Linux shutdown -r +1 command to shut down and restart the logical partition. This option is available only when the operating system is running, and not when the logical partition is in an Open Firmware state.
    Operating System Immediate The HMC issues the Linux shutdown -r now command to shut down and restart the logical partition as quickly as possible, bypassing messages to other users.
    Immediate The logical partition is restarted as quickly as possible, without notifying the logical partition.
    Dump The HMC allows the Linux operating system on the Linux logical partition to run a diagnostic procedure. After the diagnostic procedure is complete, the logical partition restarts.

    The exact diagnostic procedure depends upon which Linux operating system is installed on the logical partition and how the operating system is set to do. The operating system might run an OS debugger, the operating system might perform a main storage or system memory dump on the logical partition, or the operating system might not be set to run any diagnostic procedure at all.

  6. Click OK.
