Dell Storage Manager configuration
15 Dell EMC SC Series: VMware Site Recovery Manager Best Practices | 2007-M-BP-V
Keep in mind that each Data Collector, whether primary or remote, maintains its own user access database.
In a typical active/DR site configuration, a single Data Collector server is configured and deployed, managing
both source and destination site arrays. A single set of credentials is needed to register that Data Collector
server as an array manager for both sites.
In a typical active/active site configuration, two Data Collector servers are configured and deployed with one
managing the source site array and one managing the destination site array. Two sets of credentials are
needed to register each respective Data Collector as an array manager in SRM.
4.3 Creating dedicated SRA access accounts
For the SRA to have uninterrupted access to both arrays through the DSM Data Collector, it is recommended
to create dedicated accounts for SRM. Using dedicated accounts on each array ensures that service is not
disrupted due to a user changing their password.
Following the previous example, creating dedicated accounts requires these steps:
1. Create an account named srmadmin on both the protected site array and the recovery site array.
This account needs administrator privileges and the password assigned must be secure. For added
security, create different accounts on both systems with different passwords. The account names and
passwords are arbitrary.
2. Create a new account within Unisphere Central named srmadmin.
The srmadmin account used to access the DSM Data Collector can now be used for configuring the SC
Series credentials within the SRM Array Manager configuration.
Note: Each DSM Data Collector and SC Series array maintains its own user account database. In an
active/active SRM site configuration, two sets of credentials are used to configure the SRM array managers.
4.4 Saving restore points manually
Restore points are queried by the SRA to discover the replication state and available recovery points for data
on volumes. Saving the restore points allows the SRA to retrieve the most current information about volumes
replicated between sites.
