Perform cascaded replication (template)
Template summary
Performs a three-site cascaded replication. Sites 1 and 2 have an existing remote replication relationship.
Remote replication between sites 2 and 3 is temporarily added and point in-time snapclone copies of the
storage volumes at site 1 are remotely replicated to site 3.
A.
Con
fi
gures an existing DR group pair for synchronous replication with failsafe on unavailable
member data protection.
B.
Halts the job (waits) to ensure that data on the destination disks is identical to the source disks
(DR group normalization).
C.
When ready, continues the job and makes point-in-time snapclone copies of the storage volumes
at site 2 (which are identical to those at site1).
D.
Returns the existing DR group pair to its prior operational settings.
