Drive channel data rate detection mismatch

A mismatch in data rate has been detected in the drive channel listed in the Recovery Guru Details area.

This problem can occur for the following reasons:

The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Important: The port has been bypassed and will not transfer any data until this problem is resolved.

Recovery Steps

  1. Check the Recovery Guru Summary area to see if a failed SFP is being reported.

    If... Then...
    There is not a failed SFP being reported or the failed SFP is on a different port than what is being reported in the Details area Go to step 2.
    There is a failed SFP being reported and it is on the same port as being reported in the Details area Fix the problem using its associated recovery steps, then go to step 7.
  2. Refer to the Details area, and compare the Current data rate for the affected drive channel with the Maximum data rate for the SFP in the controller tray's affected port.

    If... Then...
    Both data rate values match Go to step 3.
    The data rate values do NOT match Perform the following steps:
    1. Select the Hardware > Tray > View/Edit > Controller Components menu option in the Array Management Window.

    2. Select SFP from the left pane.

    3. Record the Part number and supported data rate of the optimal SFPs.

    4. Remove the associated SFP from the controller tray.

    5. Insert one that matches the data rate of the storage array.

    6. Go to step 7.

  3. Check the SFP in the drive tray that is connected to the port listed in the Details area. The SFP may be failed or may not match the data rate of the rest of the storage array.

    If... Then...
    The SFP is not failed, and matches the data rate of the storage array
    • If the drive tray has data rate switches, go to step 4

    • If the drive tray does NOT have data rate switches, o to step 5.

    There is a problem with the SFP Replace the SFP with one that matches the storage array's data rate, and then go to 7.
  4. Check the data rate switches on the drive trays connected to the drive channel listed in the Details area. A data rate switch may be set to a speed that conflicts with the data rate of the controller's drive channel.

    If... Then...
    The data rate switches match the data rate of the drive channel Go to step 5.
    A data rate switch does NOT match the data rate of the drive channel Set the switch so that it matches the data rate of the drive channel, and then go to step 7.
  5. Unplug and reconnect the cable at both ends of the port specified in the Details area. Click the Recheck button to rerun the Recovery Guru.

    • If the cables are reconnected and the problem still occurs, go to step 6.

    • If reconnecting the cables fixed the problem, go to step 7.

  6. Replace the cable attached to the port specified in the Details area, and then go to step 6.

  7. Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your Technical Support Representative.
