v “Corrections to information about deployment of SnapMirror over Fibre
Channel”
v “Connection name is required to enable SnapMirror compression”
v “Change to the Snapshot copy reserve value”
v “Single file reversion to or from symbolic links using SnapRestore not
supported” on page 142
Corrections to information about deployment of SnapMirror over Fibre
Channel
The sections "Requirements for deploying SnapMirror over Fibre Channel"
and "Functionality supported by SnapMirror over Fibre Channel" have some
incorrect information about fabric configuration.
Requirements for deploying SnapMirror over Fibre Channel
The following existing content is incorrect: The SAN must be enabled for
in-order frame delivery (IOD) in some configurations.
This content is corrected as follows: The SAN must be enabled for in-order
frame delivery (IOD) if there is more than one path between the source and
destination systems.
Functionality supported by SnapMirror over Fibre Channel
The table that describes the fabric configuration options has incorrect
information about in-order delivery setting on SAN fabric. The column titled
"In-order delivery setting on SAN fabric must be" should be removed.
Connection name is required to enable SnapMirror compression
To enable SnapMirror network compression, you must specify a name for the
connection between a SnapMirror source and destination system pair using
the connection_name entry in the snapmirror.conf file. This information is
missing in the "Enabling SnapMirror network compression" topic in the Data
ONTAP 8.0 7-Mode Data Protection Online Backup and Recovery Guide.
Change to the Snapshot copy reserve value
To increase the amount of usable space on the storage system while still
retaining all the benefits of volume Snapshot copies, IBM ships all new
systems running Data ONTAP 8.0.1 GA with a smaller volume Snapshot
reserve value.
