Shutdown and Restart Procedures

7

Performing shutdown and startup tasks are necessary for the performance of the subassembly removal and replacement procedures. These procedures are specifically structured for a high availability system. At appropriate points, references will indicate that the system administrator be contacted. For example, to remove a node from a cluster in preparation for service, to rejoin a node to the cluster after servicing or, to perform certain necessary software tasks prior to maintenance of various system components. Thus, highly available data services are maintained.

7.1.1.2 Startup

  1. Begin with a safety inspection.

    a. Ensure the AC power switch on the expansion cabinet rear is off. b. Verify the power cord is plugged into the correct facilities power outlet.

  2. Turn the LOCAL/OFF/REMOTE switch is in the REMOTE position.

    Refer to Figure 7-2.

  3. Turn the AC power switch on the expansion cabinet rear to ON.

    Refer to Figure 7-2.

CAUTION Caution - Never move the system when the power is on. Failure to heed this warning may result in catastrophic disk drive failure. Always power the system off before moving it.

Imported image(10x10)

  1. Turn the key switch to (the power-on position).

    See Figure 7-1. You will hear the fans begin turning.

  2. After the cabinet has been powered on, request that the system administrator return the system to high availability.

7.1.2 Processor

Before turning off the processor power, request that the system administrator remove the node that the processor is in from the cluster. The processor can then be shutdown as indicated in the following procedure.
CAUTION Caution - To avoid damaging internal circuits, do not disconnect or plug in any cable while power is applied to the system. Exceptions to this are the fiber optic and private net cables.

7.1.2.1 Shutdown

  1. Halt the system using the appropriate commands.

  2. Wait for the system-halted message and the boot monitor prompt.

  1. Turn the key switch on the front of the server to the Standby position (fully counterclockwise).

    Refer to Figure 7-3.

图形

  1. Turn the AC power switch on the system back panel off.

    Refer to Figure 7-4.

图形

7.1.2.2 Startup

  1. Begin with a safety inspection of the system.

    a. Ensure the key switch on the front panel is in the Standby position.

    See Figure 7-3.

    b. Ensure the AC power switch on the system rear is off.

  2. Turn on the AC power switch on the rear panel.

  3. Turn the key switch to the on position.

    See Figure 7-3. You should see and hear several things happen:

  • Fans begin turning.
  • The left front panel LED (green) turns on immediately to indicate the DC power supply is receiving current.
  • The middle front panel LED (yellow) lights while POST runs for approximately 60 seconds. After 60 seconds, this LED turns off if the tests do not fail. If the LED remains lighted after 60 seconds, a test has failed.
  • The right front panel LED (green) lights to show that booting is successful and the operating system is running. If this LED does not turn on and the middle LED is on, a severe hardware fault exists.
CAUTION Warning - Never move the system when the power is on. Failure to heed this warning may result in catastrophic disk drive failure. Always power the system off before moving it.
  1. Watch the system console for possible error messages from the POST diagnostic program.

    POST tests subassemblies in the server and some interface paths between subassemblies.

  2. At the conclusion of testing, POST automatically attempts to reconfigure the system, omitting any parts of the system that have failed diagnostics.

  • If there are no faults, or if POST completes a successful reconfiguration of the detected faults, the system boots. Following a successful boot, request that the system administrator rejoin the node to the cluster.
  • If you wish to run diagnostics again, or if the system hangs, you need to press the reset switch.
  1. To activate the reset switch:

    Insert the back of a pencil or other narrow object into the small opening in the center of the metal face plate and press the reset button, See Figure 7-5.

图形

CAUTION Warning - Once the system is started, do not move or attempt to move the chassis with system power on. Failure to heed this caution may result in catastrophic disk drive failure. Always power the system off completely before attempting a move.
  1. Once the system sucessfully boots, request that the system administrator rejoin the node to the cluster.

7.1.3 SPARCstorage Array

A SPARCstorage array contains three drive trays and each tray contains ten drives. To replace a single drive or a single drive tray within a SPARCstorage array, it is not necessary to power down the SPARCstorage array, together with all drives. Instead, spin down only the drives in the tray containing the drive to be replaced as described in Section 7.1.3.3, "Single Drive/Tray Shutdown."

7.1.3.1 Complete Array Shutdown

CAUTION Caution - Do not disconnect the power cord from the wall socket when you work on the SPARCstorage Array. This connection provides a ground path that prevents damage from uncontrolled electrostatic discharge.
  1. Prior to powering down a complete SPARCstorage array, you must first request that the system administrator prepare the array for service (indicate component to be replaced) and then spin down all drives in the array trays.

  2. Once the system administrator has prepared the array for servicing and spun down all drives in the array trays, turn off the AC power switch on the rear of the SPARCstorage Array 100 Series chassis.

    See Figure 7-8.

图形

7.1.3.2 Complete Array Startup

CAUTION Warning - Never move the SPARCstorage Array when the power is on. Failure to heed this warning may result in catastrophic disk drive failure. Always power the system off before moving it.
  1. Begin with a safety inspection.

    a. Ensure that the SPARCstorage array AC power switch is off.

    See Figure 7-8.

    b. Verify that the power cord is plugged into the chassis and a wall socket.

    See Figure 7-8.

  2. Turn on the AC power switch on the chassis rear.

    You should hear the fans begin turning.

  1. Watch the front panel LCD display.

    When powering on, the LCD displays the icons shown in Figure 7-7.

Figure 7-7

It may take some time for a SPARCstorage array to boot up, depending on the total number of disk drives in the SPARCstorage array.
For example, a SPARCstorage array with eighteen disk drives may take 15 - 30 seconds to boot up, while a SPARCstorage array with thirty disks drives may take up to 2 minutes to boot up.
  1. Once POST has completed, request that the system administrator restart all drive trays within the array and then rejoin the node to the cluster.

7.1.3.3 Single Drive/Tray Shutdown

Note - The procedure for a single disk is the same as that for a tray, that is, prior to replacing a disk within a tray, you must first spin down all drives in the tray.
First request that the system administrator prepare the SPARCstorage array containing the disk or tray and then spin down all drives in the tray. Once all drives in the tray are stopped, remove the tray to access individual drives for service.

7.1.3.4 Single Drive/Tray Startup

Request that the system administrator start all drives in the tray or in the tray for the disk.

7.1.4 Terminal Concentrator

To power the terminal concentrator on or off, use the power switch on the back panel as depicted in Figure 7-8.

  2. Turn the LOCAL/REMOTE switch is in the REMOTE position.

    See Figure 7-11.

  1. Turn on the power switch on the AC distribution unit. See Figure 7-10.

Note - It will take approximately 90 seconds for the terminal concentrator to boot once the key switch switch is positioned on as indicated in the next step. Following successful booting of the concentrator, you can then bring up the processor on the system console in preparation for viewing POST/boot messages as indicated in step 5..

Imported image(10x10)

  1. Turn the key switch to (the power-on position). See Figure 7-9.

    Several things will happen:

  • The DC-powered blower fan in the top of the cabinet begins turning.
  • The left front panel LED (green) turns on immediately to indicate the DC power supply is functioning.
  • The middle front panel LED (yellow) lights immediately and should turn off after approximately 60 seconds.
  • The right front panel LED (green) lights after POST has ended to show that booting is successful.

图形

CAUTION Caution - Never move the system cabinet or the expansion cabinets when system power is on. Excessive movement can cause catastrophic disk drive failure. Always power the system OFF before moving cabinets.
  1. Watch the system console for any POST error messages.

    At the conclusion of testing, POST automatically configures the system, omitting any devices that have failed diagnostics. After POST ends, the system will boot using the new configuration.

    If the middle front panel LED remains lit after the system has booted, the system has failed POST.

Note - POST does not test drives or internal parts of SBus cards. To test these devices, run OpenBoot(TM) PROM (OBP) diagnostics manually after the system has booted. Refer to the OpenBoot Command Reference manual for instructions.
  1. To start POST again, or if the system hangs, press the reset switch on the back of the front panel.

    See Figure 7-5.

  1. After the cabinet has been powered on as described in previous steps, power on individual components as directed in the jump table at the beginning of this chapter.

  2. Once the system cabinet and individual components have been powered on, request that the system administrator return the system to high availability.

7.2.2 Processor Shutdown/Startup

You can power down a SPARCcluster 2000HA processor without powering down the associated SPARCstorage arrays, if the power distribution unit Local/Remote switch is in the Local position. With the switch in the Local position, the AC outlets (for the SPARCstorage arrays) will be powered regardless of the front panel key switch position. You can then turn the processor off using the key switch.
If you want to further ensure that power is removed from the processor, check that the Local/Remote switch is in the Local position and then unplug the power supply as indicated in the following procedure.
  1. Request that the system administrator remove the node for the processor from the cluster and then halt the operating system as follows:

  2. Halt the system using the appropriate commands.

  3. Wait for the system-halted message and the boot monitor prompt.

CAUTION Caution - Do not use the key switch to power off the system for service in this procedure until you ensure that the Local/Remote switch on the Power Sequencer in the LOCAL position. This is normally set to the Remote position as a function of initial system installation, refer to the SPARCcluster HA Server Hardware Planning and Installation Manual. If it is the Remote position, the Power Distribution unit and the SPARCstorage arrays will power off, due to a sensing circuit, when the Power Supply is unplugged.
  1. If you are not sure that the Local/Remote switch on the power supply is in the Local position, proceed as follows:

    Refer to Figure 7-13 and remove the Power Supply cover by loosening six screws (it is not necessary to remove the screws). Lift the panel and pull it to the rear.

  2. Refer to Figure 7-13 and place the Local/Remote switch on the Power Sequencer in the LOCAL position.

    (the standby position).

    The logic bay and main blower will power off. You may now service the logic bay as described in the SPARCcenter 2000 Service Manual.
