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 list -rdfg all" across both the local and remote server's.

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".

Dopey # symrdf -g DopeyDg query

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



Dopey # symrdf -sid 822 list pd

Symmetrix ID: 000290300822

There are no RDF devices that are visible to this host.


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


Prior to the "RDF" group being deleted:

In this instance, RDF group number "11" will be removed.


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




4.] Validate that the RDF group has been removed.
