Checking the Data Redundancy on an Array

Use the Check Array Redundancy option to check the on a selected only when instructed to do so by the Recovery Guru.


Important:

Use this option only under the guidance of a representative.

Keep these important guidelines in mind before you check data redundancy on an array:

To successfully perform this operation, these conditions must be present:

  1. Select the Logical tab.
  2. Select the array that you want to check.
  3. Select Advanced >> Recovery >> Check Array Redundancy .
  4. Click Yes.
  5. Click Start.

    The check redundancy operation starts. The logical drives in the array are sequentially scanned, starting from the top of the table in the logical drive dialog. These actions occur as each logical drive is scanned:

    • The logical drive is selected in the logical drive table.
    • The status of the redundancy check is shown in the Associated Status column.


    Attention:

    Possible loss of data access – A parity error (the last column in the following table) is potentially serious and could cause a permanent loss of data.

    Redundancy Check Statuses and Conditions

    Status

    Condition in Which the Status Appears

    Pending

    This is the first logical drive in the array to be scanned, and you have not clicked Start to start the redundancy check.

    or

    The redundancy check operation is being performed on other logical drives in the array.

    Checking

    The logical drive is undergoing the redundancy check.

    Passed

    The logical drive passed the redundancy check. No inconsistencies were detected in the redundancy information.

    The logical drive failed the redundancy check. Inconsistencies were detected in the redundancy information.

    Media error

    The disk drive media is defective and is unreadable.

    Parity error

    The parity is not what it should be for a given portion of the data.

    • The progress bar shows the completion percentage of the redundancy check for a single logical drive, with 100 percent being complete. If an operation error occurs before the redundancy check completes, an error message appears.


    Note:

    Clicking Cancel during a redundancy check closes the dialog. Immediately running a redundancy check on the same array might cause an error. To avoid this problem, wait one to two minutes before running another redundancy check on the same array.

  6. After the last logical drive in the array has been checked, click Done.
