7 Powering the System On and Off





To power the system on fully, read the following sections:

If you want to boot the system using the SunCD, read Section 7.4, "Booting from the SunCD."

To power the system off, read Section 7.5, "Powering Off the System."

7.1 Powering On the System

Follow these steps to power on the pedestal:

    1. Verify that the SCSI Expansion Pedestal is in the proper place and that the power and data cables are connected properly.

Caution - Make sure you are satisfied with the location the SCSI Expansion Pedestal before you power it up; moving the pedestal after it is powered up may result in disk drive failure.

    2. Turn the AC power switch located at the rear of the pedestal to the ON (|) position (see Figure 7-1).

    Figure 7-1 AC Power Switch Location on the SCSI Expansion Pedestal

    3. Open the front panel on the SCSI Expansion Pedestal.

    To open the front panel, place your hand in the top vent of the front panel and lift upward on the release latch (see Figure 7-2).

    Figure 7-2 Release Latch Location

    4. Turn the DC power switch the SCSI Expansion Pedestal to the ON (|) position.

    The DC power switch is located behind the front panel (see Figure 7-3).

    Figure 7-3 DC Power Switch Location on the SCSI Expansion Pedestal

    5. Check the LED indicators.

    Figure 7-3 shows the location of the LED indicators on the SCSI Expansion Pedestal, and Figure 7-4 shows a close-up of the indicators.

    Figure 7-4 LED Indicators

    Once the DC power switch is on, the system should respond as follows:

Note - It will take about two minutes for all the SCSI devices in the SCSI Expansion Pedestal to spin up.

    6. Turn the power on to the SPARCstation, SPARCserver 630MP, or SPARCserver 670MP.

    Refer to the installation manual you received with the system for instructions on powering on that system.

7.2 Probing the System for SCSI Devices

Once you have connected your SCSI Expansion Pedestal to your system and powered it up, you should probe your system for SCSI devices to make sure all the devices in your SCSI Expansion Pedestal are connected. The commands you will use to probe your system for SCSI devices will vary depending on what system you have your SCSI Expansion Pedestal hooked up to.

7.2.1 Probing for SCSI Devices Connected to a Three-Slot SPARCstation (SSHA Connection)

Follow these instructions to probe for SCSI devices off your SPARCstation:

    1. Back up the system files and data to tape, if necessary.
    2. Notify users that the system is going down.
    3. Use the appropriate command to halt or shut down the system.

    Once you have halted your system, you will see several system messages:

    type "n" at the "" prompt and press <return:

    This will bring you to the "ok" prompt.

    4. Probe your system for SCSI devices.

    The command you enter to probe your system for SCSI devices will vary depending on which SCSI port(s) you have your SCSI Expansion Pedestal tray(s) connected to:

      Enter the total number of SCSI devices listed here: ____

      Enter the total number of SCSI devices listed here: ____

      Enter the total number of SCSI devices listed here: ____

      Enter the total number of SCSI devices listed here: ____

    5. Add up the total number of SCSI devices listed in Step 4.

    Write that number here:____

    6. Compare the total number of SCSI devices you have in your entire system with the number of SCSI devices shown in Step 5.

    For example, if your system consists of a SPARCstation and the SCSI Expansion Pedestal, and you have a 207 Mbyte disk drive in your SPARCstation and four 1.3 Gbyte disk drives in your SCSI Expansion Pedestal, you should see a total of five SCSI devices shown in Step 5.

Note - If you connected your SCSI Expansion Pedestal to the SPARCstation using the method given in Appendix B of this manual, you will not see the disk drives in your SPARCstation listed when you probe your system for SCSI devices.

    If you find that one or more SCSI devices did not come up when you probed for SCSI devices, it could mean that the devices were not installed properly. Contact the Sun Microsystems Customer Service Center for assistance. Make sure you have the serial number of your SCSI Expansion Pedestal available before you call for assistance (Figure 7-5 shows the location of the serial number ID label).

Note - Some SCSI Expansion Pedestals may have the serial number ID label in a different location than that shown in Figure 7-5.

7.3 Installing Software, Creating File Systems, and Mounting a Disk Drive

This section provides the steps you will need to perform in order to begin using your disk drives.

There are two ways you can use the disk drives installed in your SCSI Expansion Pedestal:

Follow the instructions given in the section that pertains to your set-up.

7.3.1 Using a Disk Drive as Additional Storage

If you are going to use one or more disk drives installed in your SCSI Expansion Pedestal as additional storage, complete the following procedure. If you are going to use the disk drives installed in your SCSI Expansion Pedestal as primary storage, go to Section 7.3.2, "Using a Disk Drive as Primary Storage."

    1. Determine which version of the operating system your system is running.

    Execute the command that identifies the operating system and its version number, as appropriate for your system. See Section 1.2, "When You Need Help with UNIX(TM) Commands," for help with this command.

    2. If your system is running SunOS 4.1.1 or SunOS 4.1.1 Rev. B, install the software labeled 1.3Gbyte Disk Drive Enhancement.

    Do not install this software on later versions of SunOS or Solaris. Refer to the Product Note for 1.3Gbyte Disk Drives for software installation instructions. This software might not be shipped with disk units when a later version of SunOS or Solaris is available.

    3. Determine how many disk drives are in each tray in your SCSI Expansion Pedestal.

    Table 7-1 shows the number of disk drives that would be installed in each tray for all configuration options for your SCSI Expansion Pedestal.

    For example, if you ordered X750AR6 and X756AR6, you would see that you have two disk drives in the bottom tray (X750AR6) and two disk drives in the middle tray (X756AR6).

Note - The disk drives will be installed only in the middle and/or bottom trays in the SCSI Expansion Pedestal.

      a. Enter the appropriate command to reformat or repartition the disk, if you want to reformat or repartition the disk.

Note - Each SCSI disk drive comes pre-formatted and partitioned at the factory. You do not need to reformat the disk drive unless you want to change the default partitioning already set up.

      Refer to the documentation that came with your operating system media or the man page on the command for formatting disks for your operating system.

      b. Become superuser.
      c. Perform the following steps on each partition of the SCSI disk drive to mount each partition of the drive:
        i. Make a file system for the partition on the disk.
        ii. Make a directory for the new file system.
        iii. Mount the directory you just created.
        iv. Save the current mount state.

        If you have more partitions on the drive to mount, go back to Step i and repeat the procedure with the next partition on your drive.

        If you have mounted all the partitions of the drive, go back to Step a and repeat the procedure with the next SCSI disk drive.

After completing all of the previous steps, the procedure is complete.

7.3.2 Using a Disk Drive as Primary Storage

If you are going to use a disk drive installed in your SCSI Expansion Pedestal as primary storage (that is, the operating system will be installed on the disk drive), do the following:

    1. Install the operating system on your disk.

    Refer to the documentation that came with your operating system media.

    2. Determine which version of the operating system your system is running.

    Execute the command that identifies the operating system and its version number, as appropriate for your system. See Section 1.2, "When You Need Help with UNIX(TM) Commands," for help with this command.

    3. If your system is running SunOS 4.1.1 or SunOS 4.1.1 Rev. B, install the software labeled 1.3Gbyte Disk Drive Enhancement.

    Do not install this software on later versions of SunOS or Solaris. Refer to the Product Note for 1.3Gbyte Disk Drives for software installation instructions. This software might not be shipped with disk units when a later version of SunOS or Solaris is available.
