Workaround for Planned Failover of LiveVolumes in SRM 8.2
SRM 8.2 fails to send the ReverseReplication command to the Dell Storage Replication Adapter (SRA) during the planned
failover of LiveVolumes.
To resolve this issue, perform the following steps on the Windows servers that are running SRM 8.2 at both sites:
1. On the Windows server that is running SRM 8.2, open the vmware-dr.xml file in a text editor.
The default location of the vmware-dr.xml file is C:\Program Files\VMware\VMware vCenter Site Recovery
Manager\config\vmware-dr.xml.
2. Search for the XML tag <storage> in the file.
3. Add the following entry between the XML tags <storage> </storage> :
<forcePrepareAndReverseReplicationForNoopDevices>true</
forcePrepareAndReverseReplicationForNoopDevices>
4. Save the changes to the vmware-dr.xml file.
5. Restart the SRM services on the Windows server.
Storage Manager Scalability
To optimize performance and prevent connectivity issues, Dell EMC recommends that one Data Collector manages no more
than ten Storage Centers. A Data Collector may exceed that recommendation depending on the network latency, I/O load, and
number of volumes.
Documentation Correction
The following documentation issue is in this release:

Documentation Correction
Authentication mode and
administrator privilege requirements
for Microsoft SQL Server
The Storage Manager 2019 R1 Installation Guide contains ambiguous information about
the authentication mode and administrator privilege requirements that are required to
connect a Storage Manager Data Collector to a Microsoft SQL Server database server.
The correct authentication mode and administrator privilege requirements for Microsoft
SQL Server are:
Configure Microsoft SQL Server to use mixed mode authentication.
Use a SQL Server administrator account with sysadmin privileges to connect the
Storage Manager Data Collector to Microsoft SQL Server.
