Table 1. Limitations in Storage Manager 2020 R1.2Storage Manager 2020 R1.2 limitations
Limitation Description
Planned Failover of Live Volumes in SRM 8.2 and 8.3 SRM 8.2 and 8.3 fail to send the ReverseReplication command to the Dell Storage Replication Adapter (SRA) during the planned failover of Live Volumes. To resolve this issue, perform the following steps on the servers that are running SRM 8.2 or 8.3 at both sites:
  1. On the servers that are running SRM, open the vmware-dr.xml file in a text editor.
    • The default location of the vmware-dr.xml file in Windows is C:\Program Files\VMware\VMware vCenter Site Recovery Manager\config\vmware-dr.xml.
    • The default location of the vmware-dr.xml file in the Photon-based SRM is /opt/vmware/srm/conf/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 service on the servers at both sites.
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.
Unisphere Central features The following features are not available in Unisphere Central:
  • Chargeback
  • FluidFS management
  • PS Series Group management
