Choose the Verify... menu item to instruct CMS to
  perform a series of consistency checks on your CMS
  library. CMS verifies libraries to confirm that the
  library structure and library files are in a valid form.

  By default, CMS verifies all the elements in each library
  in the library search list.  To specify that CMS verify
  only the first occurrence of each element in the search
  list, use the Occlude option.

  When you choose Verify..., a dialog box appears, enabling
  you to specify options for the library to be verified.

1  –  Vl db

  The Verify dialog box allows you to enter information
  about the library you want to verify.

  You must supply information about whether to verify some
  or all of the elements in the library. You can also
  specify occlusion options, a remark to be stored in the
  library history, whether or not to confirm the deletion
  of any reference copies, and the options to use during
  the verify operation.

  To specify multiple elements to be verified, use wild-
  cards and/or a list of element names separated with
  commas.  If you do not supply an element specification,
  CMS verifies every element in the library.

1.1  –  Vl sf

  If you click on an object or objects before choosing
  the Verify... menu item, the Selected field contains
  those objects.  CMS performs the verify transaction on
  the selected objects.

1.2  –  Vl enf

  Fill in the Element field with the name of one or more
  element expressions to be verified.  If you do not
  supply an element name, CMS verifies every element in
  the library.

  The element expression can also be a wildcard expression
  or a group name.

  You cannot specify an element expression if you also
  specify the Recover option in this dialog box.

1.3  –  Vl rf

  Fill in the Remark field with text that is associated
  with the transaction.  The remark is permanently
  logged in the library history file.

1.4  –  Vl dbc

  Click on the Confirm reference copy deletions button
  to direct CMS to prompt you for confirmation prior
  to deleting any invalid reference copies during the
  verify/repair operation.

1.5  –  Vl wor

  Click on the Warn On Repair Button to direct CMS to
  display a pop-up message for each successful repair
  operation.

1.6  –  Vl rfa

  Click on the Repair File Attributes Only Button
  to direct CMS to only repair problems with the
  file attributes of element Data Files and reference
  copies. Other potential problems with these files
  are not repaired. Note that the library database
  file is always repaired, even when this option is
  selected

1.7  –  Vl a

  The Verify action options allow you to indicate the type
  of verification CMS should use to verify the contents of
  the library.

1.7.1  –  Vl ai

  Click on the Inspect button to verify your library
  without performing any recovery or repair operations. If
  any data in the library is invalid, CMS displays an error
  message indicating that there is an error found during
  the verification of the library.

  Choose the Recover or Repair buttons to correct the
  errors discovered by the verify transaction.

1.7.2  –  Vl ar

  Click on the Recover button to recover the library if a
  previously performed transaction was incomplete and the
  rollback mechanism did not automatically cancel the
  transaction.

1.7.3  –  Vl arr

  Click on the Repair button to repair a file or files in
  the library.  Files should be repaired if one of the
  following conditions occur:

  o  Files were not closed by CMS
  o  The checksum of elements in the library is invalid
  o  File generations have an invalid maximum record size
  o  A reference copy is invalid, missing, or duplicated
  o  A data block was not found
