Building a Metropolitan Cluster Using MetroCluster/SRDF
Setting up M by N Configurations
Chapter 4 161
To manage the BCV devices from the R1 side, you need to associate the
BCV devices with the device groups that are configured on the R1 side.
Use the following commands on hosts directly connected to the R1
Symmetrix:
# symbcv -g dgoraA associate dev 01A -rdf
# symbcv -g dgoraA associate dev 01B -rdf
# symbcv -g dgoraB associate dev 052 -rdf
# symbcv -g dgoraB associate dev 053 -rdf
Now establish the BCV devices using the following commands from the
R2 side:
# symmir -g dgoraA -full est
# symmir -g dgoraB -full est
Alternatively, you can establish the BCV devices with the following
commands from the R1 side:
# symmir -g dgoraA -full est -rdf
# symmir -g dgoraB -full est -rdf
Configuring Gatekeeper Devices
You need 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 nodes on the R1 side to define gatekeepers and associate them with
device groups:
# symgate -sid 638 define dev 010
# symgate -sid 130 define dev 009
# symgate -sid 638 -g dgoraA associate dev 010
# symgate -sid 130 -g dgoraB associate dev 009
Use the following commands on all nodes on the R2 side to define
gatekeepers and associate them with device groups:
# symgate -sid 021 define dev 002
# symgate -sid 363 define dev 00B
# symgate -sid 021 -g dgoraA associate dev 002
# symgate -sid 363 -g dgoraB associate dev 00B
