Restarting the system

In addition to checking the hardware and checking the processes, you can restart you system to reactivate an inactive system.

If the procedures for Hardware check and Checking the processes fail to correct the problem that makes your system inactive, you need to restart your system.
Note: Before restarting your system, complete a system dump.
  1. Check the state of the boot device.

    Your system boots with either a removable medium, an external device, a small computer system interface (SCSI) device, an integrated device electronics (IDE) device, or a local area network (LAN). Decide which method applies to your system, and use the following instructions to check the boot device:

    • For a removable medium, such as tape, make sure the medium is inserted correctly.
    • For IDE devices, verify that the IDE device ID settings are unique per adapter. If only one device is attached to the adapter, the IDE device ID must be set to the master device.
    • For an externally attached device, such as a tape drive, make sure:
      • The power to the device is turned on.
      • The device cables are correctly attached to the device and to the system unit.
      • The ready indicator is on (if the device has one).
    • For external SCSI devices, verify that the SCSI address settings are unique.
    • For a LAN, verify that the network is up and operable.

    If the boot device is working correctly, continue to the next step.

  2. Load your operating system by doing the following:
    1. Turn off your system's power.
    2. Wait one minute.
    3. Turn on your system's power.
    4. Wait for the system to boot.

If the operating system failed to load, boot the hard disk from maintenance mode or hardware diagnostics.

If you are still unable to restart the system, use an SRN to report the problem with your inactive system to your service representative.
