<\/p>\n

As your EMC CLARiiON, VNX, and AX series grow older, sourcing the exact part number replacements for hard drives can get harder and harder. This guide aims to educate you on how to determine the part number and see compatible part numbers for your system.<\/p>\n

<\/p>\n

<\/p>\n

Determining EMC Hard Drive Part Numbers<\/h2>\n

<\/p>\n

<\/p>\n

There is a good chance that there are many part numbers listed on a single drive pulled from an EMC array. The generic EMC Model Number does not appear on a drive (e.g.\u00a0EMC CX-SA07-010 1TB SATA Hard Drive<\/a>). The disk part number (PN) appears on a label on the front of the disk carrier. This is a nine digit Top Level Assembly (TLA) Part Number like PN 005123456<\/strong>.\u00a0There are several TLA part numbers that fall under the same EMC model number.<\/p>\n

<\/p>\n

<\/p>\n

\n
\"Determining<\/figure>\n<\/div>\n

<\/p>\n

<\/p>\n

Example:<\/strong>\u00a0Your hard drive has a TLA Part number reading\u00a0005048797. Your replacement has a TLA part number\u00a0005049070. These are both the same EMC hard drive model number CX-SA07-010 and are hot-swappable.<\/p>\n

<\/p>\n

<\/p>\n

Finding TLA Part Number in Navisphere<\/h3>\n

<\/p>\n

<\/p>\n

Follow these steps to find TLA part number for a drive in a CLARiiON array:<\/p>\n

<\/p>\n

<\/p>\n

    \n
  1. Open Navisphere by typing in the storage processor\u2019s IP address in a web browser.<\/li>\n
  2. Open array with the fault. This is usually indicated by a red \u201cF.\u201d<\/li>\n
  3. Open Physical.<\/li>\n
  4. Open the Bus and Enclosure with the fault.<\/li>\n
  5. Open Disks.<\/li>\n
  6. Right-click the disk above or below the disk with the fault and select properties. The TLA part number should be listed at the bottom.<\/li>\n<\/ol>\n

    <\/p>\n

    <\/p>\n

    Follow these steps\u00a0to check and retrieve\u00a0necessary information for\u00a0single disk failure:<\/p>\n

    <\/p>\n

    <\/p>\n

    Check the current status:<\/strong><\/p>\n

    <\/p>\n

    <\/p>\n

    1.\u00a0\u00a0\u00a0\u00a0\u00a0Log in to Navisphere manager, right-click CLARiiON name and select \u201cFaults.\u201d<\/p>\n

    <\/p>\n

    <\/p>\n

    2.\u00a0\u00a0\u00a0\u00a0\u00a0Confirm that the drive\u00a0x_x_x<\/em>\u00a0is the only faulty drive that is\u00a0 showing as \u201cRemoved.\u201d<\/p>\n

    <\/p>\n

    <\/p>\n

    3.\u00a0\u00a0\u00a0\u00a0\u00a0Expand \u201cLUN Folder\u201d and expand \u201cUnowned LUNs.\u201d Make sure no user LUN is unowned. (It\u2019s normal to see hot spares in the unowned LUNs section.)<\/p>\n

    <\/p>\n

    <\/p>\n

    Get the TLA Part number of the faulty disk:<\/strong><\/p>\n

    <\/p>\n

    <\/p>\n

    1.\u00a0\u00a0\u00a0\u00a0\u00a0Right-click SP A or SP B, select \u201cView Events\u201d, and click \u201cYes\u201d to continue.<\/p>\n

    <\/p>\n

    <\/p>\n

    2.\u00a0\u00a0\u00a0\u00a0\u00a0Click \u201cFilter\u201d in the new window, uncheck \u201cWarning\u201d and \u201cInformation,\u201d and click \u201cOK.\u201d<\/p>\n

    <\/p>\n

    <\/p>\n

    3.\u00a0\u00a0\u00a0\u00a0\u00a0Locate Event code \u201c0x7127897c\u201d and Description \u201cDisk(Bus x Enclosure x Disk x) failed,\u201d and double-click to open it.<\/p>\n

    <\/p>\n

    <\/p>\n

    4.\u00a0\u00a0\u00a0\u00a0\u00a0Record the TLA part number in the description field. It is a 9-digit number starting with \u201c005.\u201d<\/p>\n

    <\/p>\n

    <\/p>\n

    5.\u00a0\u00a0\u00a0\u00a0\u00a0Refer to following format:<\/p>\n

    <\/p>\n

    <\/p>\n

    Only one disk failure
    No Uknown LUN
    Disk Slot: x_x_x
    Disk P\/N 005xxxxxx<\/p>\n

    <\/p>\n

    Decoding EMC Model Part Numbers<\/h3>\n

    <\/p>\n

    <\/p>\n

    First two numbers\/letters in the EMC model part number indicate the product these drives are for.<\/p>\n

    <\/p>\n

    <\/p>\n

    CX \u2013 CX series
    AX \u2013 AX series
    VX\/V2\/VS\/V3\/V4 \u2013 VNX series<\/p>\n

    <\/p>\n

    <\/p>\n

    The next four series of numbers indicate Drive Type and Disk Speed (RPM), or in the case of some Fibre Channel drives Data Rate (GB\/s) and Disk Speed (RPM). We have included examples of drives on each and every legend below. Click on any attribute<\/b> below\u00a0 and it will take you to a page where you can read more on that particular drive.<\/p>\n

    Changing Bus Speed<\/strong><\/h2>\n

    <\/p>\n

    <\/p>\n

    If you install a 2 Gb legacy disk in a disk-array enclosure (DAE) on a 4 Gb bus, you\u00a0cannot\u00a0use the disk in a RAID group or thin pool until you change the bus speed to 2 Gb. You can change the bus speed with the Backend Bus Speed Reset Wizard, which is available from the Service option on the Navisphere Manager Tools<\/strong> menu. The speed reset operation reboots the storage processors.<\/p>\n
