Cancel a Portable Volume Disk Restore Operation
You can cancel the operation to restore a replication baseline from a portable volume disk to the destination Storage Center.
1. Click the Storage view.
2. In the Storage pane, select the destination Storage Center.
3. Click the Storage tab.
4. In the Storage tab navigation pane, select Repl Baseline From [ ].
5. In the right pane, on the Portable Volumes tab, right-click the volume restore that you want to cancel, then select Cancel
Replication Baseline. The Cancel Replication Baseline dialog box appears.
6. Click Yes.
Storage Center Live Volumes
A Live Volume is a replicating volume that can be mapped and active on a source and destination Storage Center at the same time.
While both Storage Centers can accept writes, when a server writes to the destination volume, the writes are redirected to the
source volume before being replicated back to the destination.
Unlike replicated volumes, Live Volume primary and secondary volumes share the same volume identity, which means that servers
recognize the primary and secondary volumes as the same volume.
Behavior of Volume QoS Settings in Live Volume Operations
Any Volume or Replication QoS settings that have been dened are enforced only on the primary side of a Live Volume. If the
secondary becomes primary as the result of a swap or DR Activate, the Volume QoS attributes and Replication QoS settings from
that system are enforced. This behavior diers from how Volume QoS settings are enforced for a replication.
Live Volume Requirements
To create Live Volumes, the requirements listed in the following table must be met.
Requirement
Description
Storage Center version The primary and secondary Storage Centers must meet the
minimum version requirements.
• Synchronous Live Volume: Version 6.5 or later
• Asynchronous Live Volume: Version 5.5 or later
NOTE: Dell recommends that both Storage Centers are
running the same version of
Storage Center.
Storage Center license The primary and secondary Storage Centers must be licensed
for Live Volume.
Storage Manager conguration The primary and secondary Storage Centers must be added to
Storage Manager.
Storage Center communication The primary and secondary Storage Centers must be connected
using Fibre Channel or iSCSI, and each Storage Center must be
dened on the other Storage Center.
• On the primary Storage Center, the secondary Storage
Center must be dened as a remote Storage Center.
• On the secondary Storage Center, the primary Storage
Center must be dened as a remote Storage Center.
QoS denitions Quality of service (QoS) denitions must be dened on the
primary and secondary Storage Centers.
