      This means the drive won't be recognized as a Netapp drive.  A
      Netapp is expected to have this flag set to TRUE.  I can change
      that, but it won't probably help at all in your case.

The strace does not contain any error which isn't expected.  Are you
sure the problem occured when you created this trace?
