Task Overview:
Performing a Share or
Partition Failback
If a NAS share or VTL partition is lost or damaged on the source system,
you can failback the share or partition to the source system using a
received snapshot on the target system. When you failback a share or
partition, it is restored on the source system just as it was at the point in
time when the snapshot was saved.
To perform a share or partition failback:
1 On the original source system, add the original target system to the
list of allowed replication sources (see Adding a Replication Source
on page 258).
Note: For the purposes of failback, the original source system is
now acting as a target because it will receive the snapshot
from the original target system.
2 On the original target system, select a received snapshot and
perform a failback operation pointing to the original source system,
and then recover the share or partition on the original source
system (see Performing a Failback For a Share on page 137 or
Performing a Failback For a Partition on page 151).
The share or partition is now available on the original source
system.
3 (Optional) If necessary, map your backup application to the restored
share or partition on the original source system.
Replication Send
The Replication Send page allows you to manage outgoing replication
activity for NAS shares or VTL partitions. You can replicate shares or
partitions on the DXi4701 (the source) to other DXi systems (the
targets). You can also schedule replication, and view the status of
current and recent replication jobs.
Note: Before you can replicate shares or partitions, you must specify a
replication target (see Adding a Replication Target on
page 251).
