    The document outlines the procedure for replacing a defective storage controller on an XtremIO storage system.

    The steps include logging into the CLI, listing clusters and storage controllers, and identifying issues such as a controller being disconnected or having a failed journal state.

    The steps include deactivating and removing the defective controller after disconnecting cables and power, and confirming its physical removal.

    Identifying the Defective Storage Controller
    To identify the defective Storage Controller, using the CLI:
    1. Log in to the XMCLI as tech.

    2. List the clusters, using the following command:


    show-clusters vertical
    Note: It is recommended to keep the CLI window in a maximized mode. Minimizing the
    window may cause the activation progress bar to be displayed on new lines instead of the
    same line.

    3. Verify that the Conn-state column shows connected.


    4. List the Storage Controllers status, using the following command:
    show-storage-controllers cluster-id="<cluster id>"

    Note: The cluster-id parameter is not mandatory for single cluster configurations.

    5. Verify which Storage Controller is problematic.

    For example: state = Disconnected OR Journal-state = failed

    6. Record the configuration data of the defective Storage Controller and refer to it when you
    configure the new Storage Controller.

    To remove the defective Storage Controller:


    1. Log in to the XMS CLI as tech.

    2. Deactivate the defective Storage Controller, using the following command:


    replace-storage-controller-prepare sc-id=<storage-controller-id>

    3. When prompted to “Proceed when Storage Controller is physically removed.” Disconnect


    all power and I/O cables from the back of the Storage Controller.

    Make sure that all cables are clearly labeled before disconnecting them from the Storage
    Controllers (i.e. SAS, Serial, IB, MGMT and Power).

    4. Remove the server from the rack. With the Server removed type “Done” to complete the
    command.

    Install the new Storage Controller:


    1. Install the server into the rack and cable it up. Verify cabling and power on the server.

    2. Wait for the server to boot (roughly 5 minutes) and update network information on the
    controller. If the storage controller was delivered without a valid XIOS image, proceed to
    Recover the Storage Controller Operating Environment.
    Using a KVM connect to the Storage Controller and configure the network.

    Log into Storage Controller with the xinstall user and configure the replaced controller
    network interface. Select 1 to enter the Configuration menu followed by 2 to enter the
    Configure local storage controller only menu.

    Recover the Storage Controller Operating Environment

    Writing the XtremIO Rescue Image to a USB Drive


    Before writing the XtremIO rescue image to a USB drive, perform the following steps:
    Note: Verify that you have a USB drive that is at least 2GB in capacity.
    1. Locate the XtremIO Rescue Image.
    2. Download the image to the local machine where the USB drive will be created.

    To write the XtremIO image to a USB drive (on Windows 7):


    Note: Before you proceed, verify that the USB drive is available.
    1. Download and unpack the Win32 Disk Imager utility
    (http://sourceforge.net/projects/win32diskimager/).

    2. Launch the Win32 Disk Imager utility on the local machine.

    3. Insert the USB drive into the USB port on the Windows machine.

    4. Under Image File in the Win32 Disk Imager dialog box, click the folder icon and select
    the XtremIO Rescue Image file you downloaded earlier.

    5. Under Device, click the drop-down menu and select the device drive letter for the USB
    drive.
    Note: Use Window Explorer to make sure that the correct drive letter is selected.

    6. Click Write to write the image file to the USB Drive; a warning appears to indicate that
    existing data on the selected drive will be overwritten.

    7. Verify that the correct drive letter is selected and click Yes to confirm.

    8. Follow the write operation progress. When the operation is completed, a message
    appears, indicating that the write was successful.

    9. From the Windows Notification Area, click Safely Remove Hardware and Eject Media.

    Re-Installing a Storage Controller

    To re-install a Storage Controller:


    1. Power-cycle the Storage Controller by unplugging and re-connecting its two power
    cables.

    2. As the Storage Controller powers up, press F6 to enter the boot device menu.

    3. When prompted, type the BIOS password (emcbios) to display the boot device menu.
    Note: If the boot device menu is not displayed, F6 was pressed too late. Go back to step
    1 and repeat the procedure.

    4. In the boot device menu, select USB device.


    Note: The menu option includes the USB drive’s brand name (e.g. "Eject Cruzer Blade"
    appears when SanDisk Cruzer Blade USB drive is used).

    5. When the Storage Controller is booted-up, select Install XtremApp from the GRUB
    menu.

    6. With the new Storage Controller installed, using the following command to complete the
    replacement:
    replace-storage-controller sc-id=<storage-controller-id>

    7. Verify Storage Controller and Cluster State.
