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.
NOTE: The Live Volume feature is not supported on storage systems with front-end SAS connectivity.
Behavior of Volume QoS Settings in Live Volume
Operations
Any Volume or Replication QoS settings that have been defined are enforced only on the primary side of a Live Volume. If the secondary
Storage Center becomes primary Storage Center as the result of a swap or DR Activate, the Volume QoS attributes and Replication QoS
settings from that Storage Center are enforced. This behavior differs 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 be running the same version of Storage Center
software.
Storage Center license The primary and secondary Storage Centers must be licensed for Live Volume.
Storage Manager configuration The primary and secondary Storage Centers must be added to Storage Manager.
NOTE: A Live Volume must use the same LUN number on both the primary and
secondary Storage Centers.
Storage Center communication The primary and secondary Storage Centers must be connected using Fibre Channel or iSCSI, and
each Storage Center must be defined on the other Storage Center.
• On the primary Storage Center, the secondary Storage Center must be defined as a remote
Storage Center.
• On the secondary Storage Center, the primary Storage Center must be defined as a remote
Storage Center.
