Site Recovery Manager configuration
32 Dell EMC SC Series: VMware Site Recovery Manager Best Practices | 2007-M-BP-V
6.2 Creating array pairs
Once an array manager has been added to each of the two sites in SRM, the arrays must be paired so that
replicated volumes can be discovered by SRM as eligible devices. In older versions of SRM, pairing was an
action that was performed after the initial installation of SRM. However, as of SRM 5.8, pairing can be
performed as part of the process of adding array managers to sites.
Arrays cannot be unpaired while downstream SRM dependencies, such as protection groups, exist.
6.3 Array manager device discovery
Whenever a new replicated datastore or RDM is added to the environment, the arrays should be rescanned
within SRM for new devices. The array pair device discovery tool can be found in the Array Based
Replication module > Manage tab. Run the device discovery on both arrays to ensure a consistent list of
devices. Non-replicated volumes will not be discovered and displayed as eligible devices in SRM. Keep this in
mind as a troubleshooting tip if datastores or RDMs are not listed as eligible devices in SRM. Conversely, all
SC Series replicated volumes are discovered as devices in SRM, even if they are not for use by vSphere (for
example, replicated volumes belonging to other storage hosts such as physical Microsoft
®
Exchange
®
, SQL
Server
®
, Oracle
®
, and file servers).
