Changes to the Storage Efficiency Management Guide

There are some changes to the existing content of the Data ONTAP 8.0 7-Mode
Storage Efficiency Management Guide.
v "Corrections to deduplication and volume SnapMirror information"

Corrections to deduplication and volume SnapMirror information

The "Deduplication and volume SnapMirror" section includes some incorrect
content.
The following existing content is incorrect: For example, an N5300 storage
system supports a maximum volume size with deduplication of 4 TB, and an
N5600 storage system supports 16 TB. When establishing a volume
SnapMirror relationship between the N5300 and N5600 storage systems, you
should ensure that the volume SnapMirror relationship is established for 4 TB.
After a failover, if the volume size on the N5600 storage system is increased to
more than 4 TB, you will not be able to perform a new baseline transfer or
resynchronize the storage systems, because the N5300 storage system has a
maximum volume size with deduplication of 4 TB.
The content is incorrect because starting with Data ONTAP 8.0.1,
deduplication can be enabled on volumes up to 16 TB for all platform models.

Changes to the Gateway Implementation Guide

There are some changes to the existing content of the Gateway Implementation
Guide.

Changes to the Gateway Implementation Guide for Native Storage
Expansion Units
New information has become available since the previous revision of the
Gateway Implementation Guide for Native Storage Expansion Units
In the Gateway Implementation Guide for Native Storage Expansion Units,
Appendix B, "Setting up and Managing Multipath Storage" says that to use
Multipath Storage with gateway systems you must configure the
fc-non-array-adapter-list environment variable. The information in this
chapter does not specify that using this variable is required only for ports on
FC adapters; it is not required for ports on SAS adapters.
