4. For each node on the R2 side (node3 and node4), assign the R2 devices to the device groups.
# symld -sid <Remote Symmetrix ID 1> -g <Device Group Name 1> add
dev 018
# symld -sid <Remote Symmetrix 1> -g <Device Group Name 1> add dev
019
# symld -sid <Remote Symmetrix ID 2> -g <Device Group Name 2> add
dev 050
# symld -sid <Remote Symmetrix ID 2> -g <Device Group Name 2> add
dev 051
5. On each node on the R2 side (node3 and node4), associate the local BCV devices to the
R2 device group.
# symbcv -g <Device Group Name 1> add dev 01A
# symbcv -g <Device Group Name 1> add dev 01B
# symbcv -d <Device Group Name 2> add dev 052
# symbcv -d <Device Group Name 2> add dev 053
6. To manage the BCV devices from the R1 side, it is necessary to associate the BCV devices
with the device groups that are configured on the R1 side. Use the following commands on
hosts that are directly connected to the R1 Symmetrix.
# symbcv -g <Device Group Name 1> associate dev 01A -rdf
# symbcv -g <Device Group Name 1> associate dev 01B -rdf
# symbcv -g <Device Group Name 2> associate dev 052 -rdf
# symbcv -g <Device Group Name 2> associate dev 053 -rdf
7. Establish the BCV devices using the following commands in the nodes on the R2 side.
symmir -g <Device Group Name 1> -full establish
symmir -g <Device Group Name 2> -full establish
8. Alternatively, establish the BCV devices with the following commands on the nodes in the R1
side.
# symmir -g <Device Group Name 1> -full establish-rdf
# symmir -g <Device Group Name 2> -full establish-rdf
Configuring gatekeeper devices
It is necessary to have a gatekeeper device for each device group in the consistency group that
will be built in a later step. Use the following commands on all the nodes on the R1 side to define
gatekeepers and associate them with device groups.
# symgate -sid <Symmetrix ID 1> define dev 010
# symgate -sid <Symmetrix ID 2> define dev 009
# symgate -sid <Symmetrix ID 1> -g <Device Group Name 1> associate dev
010
# symgate -sid <Symmetrix ID 2> -g <Device Group Name 2> associate dev
009
Use the following commands on all the nodes on the R2 side to define gatekeepers and associate
them with device groups.
# symgate -sid <Remote Symmetrix ID 1> define dev 002
# symgate -sid <Remote Symmetrix ID 2> define dev 00B
