symcfg -sid 1234 list -RA all  this will show you all the RDF directors in the array and what groups they have on them.  You can get the remote serial number and run the same command to see the other side from your local box as well.
If we have a srdf dynamic group, how we can find out the srdf director pair associated with it ?  for eg,my rdf group is 3 and I would like to know which are the srdf source and target symmetrix's srdf director associated with it.Earlier I used to collect it from SMC,currently my SMC is not working.So I would like to know whether we have any specific command that will give this info  thanks,
symcli command help
