Identifying Disk Drives

You can identify disk drives by viewing the list of disk drives on your system. Only physical drives that display during POST are shown.

To identify a disk drive:

  1. Start the ARC utility (see Running the ARC Utility).
  2. Select the controller you want, then press Enter.
  3. Select Disk Utilities.

    The Disk Utilities view provides you with the following information:

    Location

    Model

    Rev#

    Speed

    Size

    CN1=DEV1

    Box0=Slot0

    Exp0=phy0

    The manufacturer information.

    The revision number of the disk drive.

    The speed of the disk drive.

    The size of the disk drive.

    The location information of a disk drive is determined by three types of connections:

    • Direct attached drives—The connection is determined by the cable connected to a device, for example CN1 (connector 1) is connected to DEV1 (device 1). For more information, see Direct-attach Connections.
    • Storage Enclosure Processor (SEP) managed devices—The connection is determined by an active backplane. Box0 (enclosure 0) is connected to slot0 (disk drive slot 0 in the enclosure). For more information, see Backplane Connections.
    • Expanders—The connections is determined by an expander. Exp0 (expander 0) is connected to phy0 (phy 0 within a connector). For more information, see SAS Expander Connections.
    Note: Devices other than disk drives (CDROM, tape drives, etc...) are listed in order after your system disk drives.
