11.4 Receive VTL
ETERNUS CS800 copies the snapshot from the target system back to the source system.
You can then perform a recover operation to recreate the partition on the source system just
as it was at the point in time when the snapshot was saved.
Before you can failback a partition, on the original source system, you must add
the original target system to the list of allowed replication sources (see
"Adding a
Replication Source" on page 278 ). This is because, during failback, the original
target is acting as a source when it sends a snapshot to the original source.
1. To perform a partition failback:
On the target system, select a snapshot in the Snapshots List and click Failback .
The Failback Target page displays (see "Failback Target Page" on page 396 ).
Figure 250: Failback Target Page
2. (Optional) In the Failback Destination System box, type the hostname or IP address of
a new destination system to failback the partition to. (The default destination is the
original source system.)
To use hostname format, you must specify at least one DNS IP address on
the
Network page (see "Network" on page 319 ).
3. (Optional) Leave the Use Encryption check box selected to enable encryption when
sending the snapshot to the destination. Or clear the Use Encryption check box to
disable encryption when sending the snapshot to the destination.
CAUTION!
Select 128-bit encryption if you are sending data to an ETERNUS CS800 running a
system software version prior to ETERNUS CS800 2.1 Software.
