# symbcv -g dgoraA add dev 01B
# symbcv -d dgoraB add dev 052
# symbcv -d dgoraB 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 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
7. Establish the BCV devices using the following commands from the
R2 side.
# symmir -g dgoraA -full est
# symmir -g dgoraB -full est
8. Alternatively, 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
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 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
