SRDF -type R1/R2 related question
Hi Folks,
I have a question regarding SRDF.
When we createpair between R1 and R2 using the below command:
symrdf -file -sid -rdfg createpair -type R1/R2 -establish
What does -type R1/R2 signify here. Is R1/R2 similar to RDF1/RDF2? Would changing the order reverse sync from R2 to R1?
Also when synchronizing initially ..if we want to stop the sync and resume it some other point in time which command should be used.
-Thanks in Advance

Hi Tech51,
R1/R2 indicate whether the symm and devices are RDF1(source) or RDF2(target).
The Symmetrix ID specified in createpair command is the R1 side by default and due to that we are using -R1 option.You can specify the -R2 if you are mentioning R2 symm ID but that will not copy from R2 to R1.
Type R1/R2 depends upon which symm ID we mention in the command(source or target)
If you want to stop the sync,you can suspend the RDF pair and use resume option when want to resume the sync
symrdf -file -sid -rdfg -suspend
If you created a DG,use
symrdf -g -suspend
To resume
symrdf -file -sid -rdfg - resume
symrdf -g -resume

Thanks Anoop. That was very helpful.
Can you also let me know. How when I initially sync R1->R2 can i add the devices to a Device group, so that I can perform any RDF operations such as query/set mode/suspend/resume on the DG.
A command will be helpful. -Thanks again in Advance.

Hi,
You can create a DG using:
symdg create [‑type REGULAR | RDF1 | RDF2 | RDF21]
To add devices to the DG use:
symld -g add
You can create DG on both local and remote by using the above commands.
For Local: Type would be : RDF1
For Remote: Type would be : RDF2
Thanks
