Live Volume overview
39 Dell EMC SC Series: Synchronous Replication and Live Volume | CML1064
For pre-existing Live Volumes, once both SC Series arrays are upgraded to SCOS 7.3, a banner will be
displayed allowing these Live Volumes to upgraded to support ALUA capability.

Dell Storage Manager 2018 and newer provides guidance through the upgrade process. All Live Volumes can
be upgraded, or just a partial subset of Live Volumes can be upgraded if not all storage host operating system
types meet the requirements.
Microsoft Windows, Hyper-V, or vSphere Live Volumes can be upgraded for ALUA capability
The next task in the wizard provides an option to unmap and remap the secondary Live Volume mappings to
the storage host. Depending on the operating system of the storage host, resetting the secondary Live
Volume mappings, or alternatively rebooting the storage host, may be necessary to cleanly pick up the ALUA
state changes on the Live Volume. This is a flexible option available to the administrator performing the
upgrade. Be aware of the impact of either operation. Testing revealed that vSphere hosts require a reboot.
The default action in the workflow is to not reset the secondary server mappings.
Reset the secondary Live Volume mappings or reboot the storage host as necessary
