Data Replication Procedures

Use the following command from a host that connects to the
secondary Symmetrix:
# symrdf -g <secsymdevgrpname> -full restore -bcv
5. Use the following command to check the data restore from the R2
devices in the recovery Symmetrix to the BCV/R1 devices in the
secondary Symmetrix. If the "RDF Pair STATE" column shows the
state "Synchronized" for all the devices, the data restore completed.
From a host that connects to the recovery Symmetrix:
# symrdf -g <recsymdevgrpname> query
From a host that connects to the secondary Symmetrix:
# symrdf -g <secsymdevgrpname> query -bcv
6. Once the restore completes, split the SRDF link between secondary
Symmetrix and recovery Symmetrix. From a host that connects to
the recovery Symmetrix:
# symrdf -g <recsymdevgrpname> split
From a host that connects to the secondary Symmetrix:
# symrdf -g <secsymdevgrpname> split -bcv
7. Re-establish the BCV/R1 devices in the secondary Symmetrix as
mirrors of the standard devices. Restore the data from the BCV/R1
devices to the R2 standard devices. From a host that connects to the
recovery Symmetrix:
# symmir -f <secbcvdev_textfile> -sid <secsymid> -full
restore
From a host that connects to the secondary Symmetrix:
# symmir -g <secsymdevgrpname> -full restore
8. Use the following command to check the data restore from the
BCV/R1 devices in the R2 standard devices in the secondary
Symmetrix. If the "RDF Pair STATE" column shows the state
"Restored" for all the devices, the data restore completed. From a
host that connects to the recovery Symmetrix:
# symmir -f <secbcvdev_textfile> -sid <secsymid> query
From a host that connects to the secondary Symmetrix:
# symmir -g <secsymdevgrpname> query
