No DNS forward and revers lookup between SmartDisk’s

1/ verify that source and target SmartDisk are licensed for deduplication using the following command on both SmartDisk’s.

smartdisk license --show

2/ verify that deduplication is enabled on the SmartDisk’s using following command

smartdisk config --show

3/ configure DNS forward and revers lookup for both SmartDisk

If the SmartDisk’s are using optimized replication over WAN or there is no DNS server configure the hosts file on both SmartDisk’s to contain both SmartDisk.
