    How to Install the SAS hard disk drive

    Disk drives for Serial-Attached SCSI (SAS) is distinguished by easy installation procedure. To ensure proper operation of these drives, you don't need to install any jumpers, terminators, or other settings.

    Each disc is equipped with a SAS interface separate cable that connects to the host adapter or controller, SAS. With some types of controllers, SAS can use cables to connect multiple devices (or port replicator). Unlike disk drives (Parallel) SCSI, in this case there is no need to assign identifiers, as each disk is connected to a single port and all the identifiers assigned by the controller.

    SAS drives can be used simultaneously with SCSI or Serial ATA (SATA), if the motherboard and the host adapter supports both of these interfaces. Moreover, in the presence of suitable ports can be connected to the disk controller SATA drives along with SAS (but drives SAS, connected to the controller SATA, will not work).


    BIOS configuration

    In most modern computers through the system setup program (CMOS or BIOS) device discovery is done automatically. When the system starts happening automatically recognize the disc, and, as a rule, the screen displays the model number. Model numbers Seagate hard drives begin with the letters ST.

    Note: Sometimes the BIOS SAS-controller has its own configuration utility system, which is absent in the standard BIOS on the motherboard. In this case the model number of SAS drives will only appear in the message SAS BIOS. For more information about configuring the BIOS settings for the disk contained in the SAS documentation for your motherboard or controller SAS.

    Important: Special note for users of RAID-host adapter. For many RAID-HBA with SAS interface you want to assign the disk to the array to the operating system to work with the disk. For information on the appointment of the disk to the array controller, see the documentation for the SAS.

    Other recommendations : Make sure that the SAS channels are included. In most of the system BIOS setup utility there is a possibility to disable port SAS. If the controller does not detect the disk, make sure that all ports of SAS included.

    Precautions / protection from electrostatic

    • Hard drives are fragile products. Keep the disk from shocks and jolts. Take a drive by its edges case.

    • Electronics drive is extremely sensitive to static electricity. To keep the installation disc in antistatic packaging. Put the cuff contact with the ground pin. Make sure that contact with the drive elements do not have static electricity. Do not use an ohmmeter to the circuit boards.

    • Use caution when working with equipment, is under stress.

    • Do not disassemble the drive, otherwise the warranty will be void.

    • Drive for warranty replacement should be returned to the collection, even if only a few defective items.

    • Do not push and do not attach a label on the circuit board or on the top cover of the disc.


    Installation Instructions


    1. Attach the drive on a stand or tray.

    Most of the systems that support the interface of SAS, equipped with trays or holders for the drive, which allows you to drive "on hot".
    Attach the disc in the tray or pedestal using the four mounting screws 6-32 UNC. Do not tighten the screws too much. The disc can be installed both horizontally and vertically.

    Note. To connect SAS drives do not require cables and cable interfaces. However, you can connect the drives and using high-quality cables up to 4 meters (cable interface).

    2. Installation CD


    Install tray or stand in the appropriate compartment of the system. Thus the disc are connected to SAS. Connector SAS, usually located on the rear panel.

    Note. Installing the drive is carried out without the jumpers and terminators. Power supply via plug SAS.

    3. Formatting disk

    Disk comes formatted at a low level. Perform low-level format once again not required, except in cases of diagnostic controller. The process of low-level formatting can not be interrupted, as this may damage the disc. Low-level formatting takes up to 1,5 hours for models ST3146854SS, 1 hour for models ST373454SS and 30 minutes for models ST336754SS.
    Provide protection in case of power failure and blackouts during formatting.

    You can also use the software Seagate SeaTools for DOS, to perform a full format. But we should remember that this tool can not work with drives connected to RAID-array.

    Warning: Formatting a disk destroys all data. This should be taken into account at the start of formatting. Disks on which information is stored, it should be formatted only if you intend to delete all data. Seagate is not responsible for any loss of data.

    Operating Systems

    Cheetah drives are compatible with different operating systems. Information on formatting and preparing the hard drive to work in a particular operating system is contained in the user manual OS or host adapter (controller) SAS.

    Hot-swap disk

    Hot Swap feature allows you to install and remove the drive without powering down the system.

    Parameters promotion drive

    Run the disk depends on the system parameters that determine the sequence of promotion drive. In most systems, with only the two drives, promotion starts immediately after power to the wheels. Systems with large numbers of drives can be configured so that the wheels are included at different times. This allows the system to avoid overloading the computer's power.

    Information about how to change the startup disk options is contained in the documentation that came with your computer or host adapter SAS.


    To install a SAS hard disk drive, complete the following steps:

    1. Read Safety and the Installation guidelines.

    2. Shut down the operating system, turn off the blade server, and remove the blade server from the BladeCenter® unit. See Removing the blade server from a BladeCenter unit.

    3. Carefully lay the blade server on a flat, static-protective surface, with the cover side up.

    4. Open and remove the blade server cover. See Removing the blade server cover.

    5. Locate the SAS connector for the hard disk drive.

    6. Install the appropriate drive.

    * Install the front SAS hard disk drive:

    1. Unlatch the bezel to increase the ease of installing the drive. (You do not have to remove the bezel.)

    2. Place the drive into the hard disk drive tray and push it toward the rear of the blade, into the connector until the drive moves past the lever at the front of the tray.

    Attention: Do not press on the top of the drive. Pressing the top might damage the drive.

    3. Latch the bezel.

    * Install the rear SAS hard disk drive:

    1. If a standard-form-factor expansion card is installed in the rear drive SAS connector 1 location, remove the expansion card, remove the expansion card and its mounting bracket, and save the screws that secure the tray to the system board. Store the screws in a safe place.

    2. Secure the SAS connector drive tray to the system board with the screws from the option kit.

    3. Place the drive into the hard disk drive tray and push it toward the rear of the blade, into the connector until the drive moves past the lever at the front of the tray.

    Attention: Do not press on the top of the drive. Pressing the top might damage the drive.

    7. Install and close the blade server cover.

    Troubleshooting

    Problem: The drive does not spin up.
    • Remove the disc, re-secure it in a tray or on a stand and reinsert into the bay for a hard disk. Make sure that the disk is not broken contact with the connector SAS on the back of the device.

    • Check your startup disk, installed on the host adapter.

    • If possible, install the drive in another bay or use a different port.

    • Try to connect to the same port or set in the same compartment of another disk.



    Problem: The computer can not recognize the disc.

    • Make sure that the disk included with the configuration utility HBA SAS.

    • If so, then the controller recognize the disc. Verify that the SAS controller drivers loaded correctly. Instructions for downloading drivers controllers, see the documentation for the controller card.

    • When you install the operating system on the hard drive should boot from the CD-ROM of the operating system and press F6, when requested (usually such a request remains on the screen a few seconds.)

    • Installing Windows 2000 or XP: Further, the installation proceeds normally, and the screen will display all the standard message, but then the screen to install drivers for the main processor bus adapter (HBA) or controller.

    • Installing Windows Vista: Click Load Driver, when it will be offered. The procedure described above with pressing F6 may be required or not required depending on specific conditions.

    Re: How to Install the SAS hard disk drive

    I was facing a issue of not detecting of the sas disk. For that you must recheck the connection of many SAS disk on motherboard ASUS P6T Deluxe X 58, 6 ports for serial ATA are supported by the Northbridge and two other ports are managed by Marvell chip that supports the disc pack ONLY SAS. If you checked the SAS drivers were available for loading at startup when you boot from the DVD 7.

    I will recommend you to go through the below manual which can guide you in more detail way. The setup is bit complicated, but with the help of manual you can properly configure the same. You have to manage the same from gui interface. If possible try to find the manual of your system. There can be chances that settings might differ system to system.
