Problem conclusion

• This problem was fixed.
  Affected platforms: AIX, Linux, and Windows.
  
  ANR8758W The number of online drives in virtual tape library
  ABCD does not match the number of
  online drive paths for source XYZ.
  The number of online drives is 789 and the number of online
  drive paths is 123.
  
  Explanation
  If the number of online drives in the library does not match the
  number of online
  paths to drives in the library for any applicable source, the
  server might
  choose a drive that lacks a valid path definition. The server
  then retries the
  mount operation, and any retry might adversely affect mount
  performance.
  
  SystemAction
  Server operations continue. However, this message indicates that
  there might be
  a mount retry if the selected drive does not have a valid online
  path.
  
  UserResponse
  To resolve the issue, complete the following steps:
  1. Evaluate all drive path definitions.
  2. For any drives that lack a path definition for any applicable
  source (for example,
  storage agents), define drive paths.
  3. Validate that all drive path definitions are online.
  4. If a drive path is offline because of a hardware issue,
  resolve the hardware issue
  and update the path so that it is online.
  5. If SAN-attached and NAS tape drives are configured in the
  same library, separate the
  tape drives into two libraries. Ensure that each library has
  only one type of attached
  tape drive.
