Preparing the SRA environment

Before you install the IBM® Storwize® Family SRA, you must prepare the storage environment.

1. Verify that the supported storage system microcode version is used (for information, refer to the release notes).
2. Create appropriate-sized target volumes on the recovery (secondary) site Storwize Family. If you are using the IBM SAN Volume Controller, create Metro/Global-Mirror relationships between the source and target volumes and add the relationships to consistency groups, as needed. If you are using IBM SVC Stretched Cluster, create appropriate-sized stretched volumes as needed.

   Note: For more information about Metro/Global Mirror Copy Services, download the IBM SAN Volume Controller Advanced Copy Services Implementation PDF. For more information about IBM SVC Stretched Cluster, click here.

3. Create a user on the Storwize Family with the appropriate privileges for the Storwize Family SRA. For SRA non-preconfigured settings, a user with "Administrator" or higher privilege is needed. For SRA preconfigured settings, a user with "CopyOperator" or higher privilege is needed.

   Important: Use the same user name and password on both the protected (primary) and the recovery site.

   Note: SRA only supports non-preconfigured settings for IBM SVC Stretched Cluster.
