Collect and Understand Replication/Deduplication Configurations

The first step for the removal of replication/deduplication is to understand your current replication/deduplication configurations. The configuration information includes:

  • Which file systems are snpolicy-managed file systems and where are they mounted?
  • What replication/deduplication policies have been defined? Is a policy defined for deduplication only, replication only, or replication with deduplication?
  • Does the snpolicy-managed file system work as a replication source site, or target site or both? Where are the target sites which are defined in the replication policies on source site?
  • Which directories are source directories for the source site file systems, which directories are realized namespaces for the target site file systems? Is there a TSM relation point associated with the source directory or target namespace?

Note: On a target, the realized namespace must land under a TSM relation point.

  • Where is the blockpool repository located? Is the file system where the blockpool repository resides only used for the blockpool?

Such information can be acquired either through the GUI or command line. Start from the replication source side host; obtain the list of target site host(s); then collect the configuration information on all targets. For deduplication-only configuration, there are no target hosts involved.
