  • Page 39: Attach

    Attach The Attach operation creates a link so the IO Accelerator interacts with the operating system. In most cases, the operating system driver automatically attaches the installed IO Accelerator(s) at boot time, so you only need to use Attach when you manually detach an IO Accelerator (such as to perform a low-level format).
  • Page 40 If the selected drive is already attached, the Attach Now button will grey-out. Click Attach Now to confirm the operation. Attach will connect the device. The Attach operation’s progress bar will appear in the Device Tree. The bar’s color varies: •...

  • Page 41: Detach

    When you click on Attach Now, ioManager will proceed to connect only the detached devices. Detach Detach disconnects your IO Accelerator from the operating system. Once detached, the device will not be accessible to users or applications. (You will need to use Attach to make it accessible.) You should only need to detach an IO Accelerator to perform a low-level format or a firmware upgrade.
  • Page 42 Click Detach. The ioManager console will ask you to confirm this: Click Detach Now. (If the selected device is already detached, the Detach Now button will grey-out.) Detach will disconnect the device. The Detach operation’s progress bar will appear in the Device Tree.
  • Page 43 Your IO Accelerator comes pre-formatted, so generally it’s not necessary to use this option. However, you would use it if you: • Need to re-format the drive for performance reasons. • Are instructed to do so by HP Customer Support. NOTE: The ioManager performs a low-level format that is different from a format performed by an operating system using standard disk management utilities.
  • Page 44 Click Format Now to perform the format. CAUTION: Formatting an IO Accelerator will destroy any data still on the device. If you have not backed up data to another device, choose Cancel to abort the format. The selected drive(s) will display a blue progress bar as the format occurs showing both the percentage as well as the estimated time remaining to complete the format: When the format completes, the progress bar turns green: Click the X next to the progress bar to close the message.
  • Page 45 The Firmware Update operation lets you upgrade the IO Accelerator’s firmware. You should upgrade the firmware only if: • The Windows System Event Log reports a problem due to out-of-date firmware or • if instructed to do so by HP Customer Support. NOTE: In most cases, if you upgrade the IO Accelerator firmware you will need to upgrade the IO Accelerator driver as well.
  • Page 46 WARNING! Interrupting an update while it is in progress can result in permanent damage to the device. Never use the Windows Task Manager to stop the update. (For this same reason, ioManager disables the Cancel button during the update process.) If the operation fails, it is critical that you restart this operation and complete it successfully before a reboot occurs to prevent damage to the device.
  • Page 47 The selected drive(s) will display a blue progress bar as the update occurs showing both the percentage as well as the estimated time remaining to complete the update: When the firmware update completes, the progress bar turns green: Click the X next to the progress bar to close the message. Use Attach to restore the operating system access to the IO Accelerator.
  • Page 48 The ioManager program checks to see if the selected firmware update is required for the selected device. If the update and the current firmware are the same, ioManager will display this by showing the firmware update and installed version numbers and the equal sign: The ioManager program will grey-out the Update Now button as this update is not required.
