Hi Sandy,  I can help you in setting up the cascaded srdf.  E.g:   [IMAGE] Step 1: create a text file with <025 035> symrdf -sid siteA -rdfg 10 createpair -f -type r1  Step 2: create another text file <035 045> symrdf -sid siteB -rdfg 20 createpair -f 
   -type r1 -rdf_mode acp_disk 
   After running createpair at Site B, the device 035 will be converted to a R21 device.  Hope this helps..  regards, Saurabh
Hi Folks ,  I am ware of the Cascade SRDF conceptually but i just want to note down how it will be implemeted step by step. I tried lot to search into powerlink PDF's which will help me to note down the commands but i am unlucky.   Can some one help with commands and validate my below steps.  Please feel free to add if i am missing anything.  Example :  Site A --> Site B --> Site C  ( Assuming all site having dynamic SRDF bit enabled )   Step 1 : Setup SRDF between devices on Site A and  Site B - Its very easy using "createpair command "  Step 2 : Make R2 device on Site B as R21 - Not sure how to do this , also not sure if we need to do this manually using commands. Step 3:  Setup SRDF between devices on Site B and  Site C - Should be easy using "createpair command " only if the Site B device is in R21 state.   Thanks in Advance.  Regards OnlySandy
