#paircreate –g dg13 –f async –nocsus –vl –c 15 –jp <Journal_id> -js <Journal_id>

5.Once the Delta Resync pair is created, issue the horctakeover command at DC1 so that the data source is at DC1. This suspends dg23 device group pair. Resync the dg23 device group using pairesync command:

#horctakeover –g dg12

#pairresync –g dg23

Creating Device Group Pairs for Multi-Hop Bi-Link configuration

For a Multi-Hop-Bi-Link configuration, first create the Continuous Access Sync or Continuous Access Journal pair between DC1 and DC2. Create the Continuous Access Journal pair dg23 after creating the pair between DC1 and DC2:

1.Create the Continuous Access sync or Journal device group between DC1 and DC2.

a.When using 3DC Sync/CAJ replication, create the Continuous Access Synchronous device group pair dg12 from any node in DC1:

# paircreate –g dg12 –f <data or never> –vl –c 15

or

When using 3DC CAJ/CAJ replication, create the Continuous Access Journal device group pair dg12 from any node in DC1:

#paircreate –g dg12 –f async –vl –c 15 –jp <Journal_id> -js <Journal_id>

b. Wait for the PAIR state to come up for the dg12 device group.

#pairevtwait -g dg12 -t 300 -s pair

2.Create Continuous Access Journal device group pair dg23 between DC2 and DC3 from any DC2 node:

— paircreate -g dg23 -vl -f async -c 15 -jp <Journal_id> -js <Journal_id>

Creating Device Group Pairs for Multi-Target Bi-Link configuration

For a Multi-Target-Bi-Link configuration, first create the Continuous Access-Syncor Continuous Access Journal pair between DC1 and DC2. Then create the Continuous Access journal pair between DC1 and DC3. Use the following to create the pairs:

1.Create the Continuous Access sync or Journal device group between DC1 and DC2.

a.When using 3DC Sync/CAJ replication, create the Continuous Access Synchronous device group pair dg12 from any node in DC1:

# paircreate –g dg12 –f <data or never> –vl –c 15

or

When using 3DC CAJ/CAJ replication, create the Continuous Access Journal device group pair dg12 from any node in DC1:

#paircreate –g dg12 –f async –vl –c 15 –jp <Journal_id> -js <Journal_id>

b. Wait for the PAIR state to come up for the dg12 device group.

#pairevtwait -g dg12 -t 300 -s pair

2.Create Continuous Access Journal device group pair dg13 between DC1 and DC3 from any DC1 node:

— paircreate -g dg23 -vl -f async -c 15 -jp <Journal_id> -js <Journal_id>

NOTE: Paired devices must be of compatible sizes and types. Only OPEN-V LUNs are supported for Three Data Center configuration.
