ONTAP 9.x

Issue

  • When migrating data using a migration tool (Robocopy, GSRichCopy360, BeyondCompare, etc.) to ONTAP 9, some file names will be converted to 8.3 file names resulting in collisions and files being overwritten as multiple files may be converted to the same name.

Example:

75TON~1 (extra).ico and 75TON~~1.ico will both be converted to the same 8.3 file name.

  • When copying a file of which name includes ~ (tilde) to a CIFS share on ONTAP, it fails due to "Could not find this item"

Example:

  1. Copy a file named "Abcdefg-001.txt" to a CIFS share in ONTAP.
  2. Copy a file named "Abcdef~1.txt" to the same CIFS share. It fails due to the error.
