Description
Description
This document attempts to explain the steps required to remove the EMC SRDF "RDF" group configuration.
In this instance, the configuration consists of "4" EMC SRDF "R1" devices presented to production server "Dopey" from EMC Symmetrix id (SID) "822". An additional "4" EMC SRDF "R2" devices have been presented to DR server "Bashful" from EMC Symmetrix ID (SID) "414".
Figure 1.0
Steps:
In this instance the "RDF" group "Dopey" will be removed.
1.] List the current EMC SRDF "RDF" groups using "symcfg -sid

2.] Ensure the replication status has been suspended and corresponding "RDF" group pairing have been deleted.
In this instance, the EMC DeviceGroup is called "DopeyDg".

Device group 'DopeyDg' is not an RDF group.
There are no RDF devices that are visible to this host.

3.] Continue to remove the "RDF" group.

Dopey # symrdf removegrp -sid 822 -rdfg 11
Execute a Dynamic RDF Removegrp operation for
Group Number: '11' for Symm: 000290300822 (y/[n]) ? y
Successfully Removed Dynamic RDF Group (Num: '11') for Symm: 000290300822
