Enable AIR on DataDomain

The steps are (assume DD7200 is the source DataDomain and DD7200A is the destination DataDomain):

1) Create an storage unit on the source DataDomain

ddboost storage unit create airA

2) Create an storage unit on the destination DataDomain

ddboost storage unit create airB

3) Link them

On DD7200

ddboost association create aira replicate-to DD7200A airb 

On DD7200A

ddboost association create airb replicate-from DD7200 aira

4) On source NetBackup master server, create a Diskpool that must target the volume created in Step 1

Keep in mind that if that volume does not appear as a "Replication Source" type, then Step 3 is incorrect

5) On source NetBackup master server, create an SLP (we named it AIRTEST) containing one backup against the storage unit type source (in our case aira) and a replication

6) On source NetBackup master server create a test backup policy, targeting in the Policy storage the SLP created in step 5

7) On destination NetBackup master server, create a Diskpool that must target the volume created in Step 2
That volume must be of type Replication target. Otherwise Step 3 was not performed or performed incorrectly

8) On destination NetBackup master server, create an SLP with the same name as in Step 5 (in this case AIRTEST), but it must be an Import operation against the DiskPool created in Step 7

When you start the backup in source NetBackup, a ddbost job will run against the source DataDomain. When the backup completes, a replication from DataDomain source to DataDomain destination will start.

Once the replication finishes an event will be generated (you should be able to see it with # ddboost event show). That notifies destination NB that an import must be started. You will see an import job in destination NetBackup Master Server.

This is very textual, but it is how it works,,!
