DF-compatibility support for disk LUNs
Table 19 and Table 20 may be used as a reference for establishing disk LUN policies in support of
DataFort firmware versions.

Brocade handling for DF disk LUNs - Read Brocade handling for DF-compatible encryption
- Write
Version 1.x The encryption switch will support reading and
decrypting the disk LUNs encrypted by this version of
DataFort. The DF-compatible license is required.
The encryption switch will not support writing disk LUNs in
this version format. Only the DataFort firmware version 3.x
compatible encryption (metadata and algorithm) is
supported for writing and encrypting the disk LUNs. This
requires DF-compatible encryption mode to be set on the
LUN and a DF-compatible license.
Version 2.x (No
Metadata on the LUN)
The encryption switch will support reading and
decrypting the disk LUNs encrypted by this version of
DataFort. The DF-compatible license is required.
The encryption switch will not support writing disk LUNs in
this version format. Only the DataFort firmware version 3.x
compatible encryption (metadata and algorithm) is
supported for writing and encrypting the disk LUNs. This
requires DF-compatible encryption mode to be set on the
LUN and a DF-compatible license.
Version 3.x The encryption switch will support reading and
decrypting disk LUNs encrypted by this version of
DataFort. The DF-compatible license is required.
The encryption switch will support writing and encrypting
the disk LUNs in this version format when DF-compatible
encryption mode is set and DF-compatible License is
present.
Note: Brocade also supports creating new DataFort
version 3.x LUNs.
