5.2.11 Initialize Snap Data Volume
This screen is used to initialize a Snap Data Volume (SDV) for use as a Sn apOPC/SnapOPC+
copy destination.
SnapOPC/SnapOPC+ are Advanced Copy functions. The [Create Logical Volume] function is
used to create a Snap Data Volume as a SnapOPC/SnapOPC+ copy destination. The Snap
Data Volume contains both data space and copy control information.
If an operational error or other mistake causes a large amount of data to be written by the host to
the Snap Data Volume, the capacity of the SnapOPC/SnapO PC+ copy destination may prove
insufficient. When the amount of data written to a Snap Data Volume exceeds its capacity, the
ETERNUS DX400/DX8000 series reports this to the host, and data writing is disabled. This func-
tion may also be used to reinitialize a Snap Data Volume when this has occurred.
The data space becomes unavailable after the Snap Data Volume is initialized.
• When the format ends abnormally or ends partially abnormally, an
error screen appears. Click the [OK] button to return to the [Menu]
screen.
• When exceeding the maximum capacity of volumes that can be
formatted concurrently, a message to that effect appears. Wait
until the current format process is complete, and then format the
volumes that failed to format. When Thin Provisioning Volumes
fail to format, "Unknown" is displayed as the result of the format
starting process. When volumes other than Thin Provisioning
Volumes fail to format, "Error" or "Not formatted" is displayed as
the result of the format starting process.
• If a Snap Data Volume is initialized, access to the d a t a i n t h e v o l u m e i s
lost. Make sure to backup any required data beforehand.
• In the following cases, initialization of Snap Data Volume cannot be
performed by this function.
- When there is no volume to be initialized
- When the volume to be initialized is not a Snap Data Volume
- When the status of the volume to be initialized is not Available
- When a copy session is already set for the volume to be initialized
- When the LDE is operating in the RAID Group to which the
initialization target volume belongs
- When the [Initialize Snap Data Volume] is operating in the ETERNUS
DX400/DX8000 series
• Only one Snap Data Volume may be initialized at a time.
