Preparing to remove an IOM

Before removing a I/O module (IOM), collect support data about your storage system and locate the failed component.

You can determine if you have a failed IOM in these ways:
  • The Recovery Guru in ThinkSystem System Manager software directs you to replace a failed IOM.
    Note
    Before replacing an IOM, select Recheck from the Recovery Guru to ensure no other items must be addressed first.
  • The amber Attention LED on the IOM is on, indicating that the component has a fault.
    Attention
    If both IOMs in the shelf have their Attention LEDs on, contact technical support for assistance.
  1. Collect support data for your storage array.

    Collecting support data before and after replacing a component ensures you can send a full set of logs to technical support in case the replacement does not resolve the problem.

    OptionDescription
    ThinkSystem System Manager

    1. Select Support > Support Center > Diagnostics.

    2. Select Collect Support Data.

    3. Click Collect.

    The file is saved in the Downloads folder for your browser with the name supportdata.7z.

    From the SMCli

    Execute the following command: smcli <ip address> -u <userid> -p <password> -c "save storageArray supportData file=\"filename.7z\";"

  2. From ThinkSystem System Manager, determine which IOM has failed.
    1. Select Hardware.
    2. Look at the IOM icon to the right of the Shelf drop-down lists to determine which shelf has the failed IOM. If an IOM has failed, the icon will be red.
    3. When you find the shelf with the red IOM icon, select Show back of shelf.
    4. On the IOMs tab, look at the status of the two IOMs to determine which IOM must be replaced.

      An IOM with a Failed status must be replaced.

      Attention
      If the second IOM in the drive shelf does not have Optimal status, do not attempt to hot-swap the IOM. Instead, contact technical support for assistance.
      Note
      You can also find the information about the failed IOM in the Details area of the Recovery Guru, or you can review the information displayed for the drive shelf.
  3. If you need help physically finding this IOM in your storage array, turn on the locate LEDs for the shelf and the IOMs.
    1. Select Hardware.
    2. Select Shelf > Turn on locator light.
      The following LEDs turn on:

      • The blue Locate LED on the shelf's operator display panel (front view)

      • The blue Locate LEDs on both the failed IOM and the optimal IOM within that shelf (back view)

  4. From the back of the storage array, look at the LEDs to determine which IOM to replace.
