The pairing relationship is defined at the device file level.
The device file (-file) option directs the specified operation in the symrdf
command to a device file.
The device file contains device pairs (SymDevnames) listing
a pair for each line.
Device files can include comment lines that begin with the pound
The following example illustrates the file format, which specifies three
#00A3 0105 (To be reinstalled later)
Any suggestion/comment is much appreciated.
But it looks like in your earlier posting of SRDF steps you haven't introduced any command with the file option. Please correct me if i'm wrong.
This is for SRDF/S. SRDF/A is some more complex.

Hi guys -
I'm going to move this over to the Support Forums as well. It is great how everyone is contributing, thanks so much!
One thing to be aware of: you need a very thorough understanding of what these commands do, and what the unintended consequences of running a certain command with a certain flag will be on your storage environment. It is possible to use these commands incorrectly, and the results of that could be very, very bad.
Managing a storage array is something you really must have formal training on, especially when you are first starting out!
So, I'm going to move this over to the support forums where our services folks can help you all keep this converstation going!
Thanks Alexey Yakovenko,
Now I got an idea how to pairup devices, create Dynamic Groups and perform Dynamic SRDF operations.
Once again thanks to EMC Community. If anybody could be more explain more by taking an example that would be great.
Some suggessition from my side for creating new srdf group
Create dynamic rdf group
Build dynamic SRDF pairs
Perform the initial SRDF full establish
Change RDF mode
symrdf addgrp -label new-group-name -sid 123 -rdfg 01 -dir 9d,8d -remote_sid 345 -remote_dir 9d,8d -remote_rdfg 01
symrdf createpair -file pair.txt -type r1 -sid 123 -rdfg 01 -invalidate r2 -nop
symrdf -g new-group-name establish -full
symrdf -g new-group-name set mode sync
But I need steps for
How we can add and delete device pair when we use dynamic rdf group with SRDF/S mode
How we add and delete device pair when we use dynamic rdf group with SRDF/A mode
