Dynamic SRDF to migrate host
Hi,
I need to migrate a W2K host in a "lab" environment. I could use host based utilities to do this, but I would like to configure and use dynamic rdf as a learning experience.
The test host is connected to a DMX-3 and I need to move it to a DMX-1000. Both are in the same data center. I have plenty of ports on both symm's. The SRDF SYMCLI document makes it sound like all I need to do is:
configure dynamic_rdf on both symms (symmconfigure)
zone the FA's together
use "symrdf addgrp" to create the new group.
Add devices to the group
Can this be done or am I wasting my time?
Thanks,
Chatch

You will need to convert your FA ports to RA ports. That involves a bin file change that that only the EMC CE's can do. You also have to make sure that the microcode is compatable on both DMX units. I'm not sure if the DMX1000 on the R2 side from a DMX3 is supported. There are all kinds of crazy things that happen when you go from a Sym 6 (DMX1000, 2000, and 3000 etc) to R2s on the DMX3 with SRDF. This is because there is an architectural mismatch internally. The DMX3 is 64k blocks instead of 32k. Although EMC claims this works fine, it still gernerated thousands of error messages on the hosts.
Your best bet is to get EMC to help you.

install dynamic RDF is not so easy if today you don't have already some RDF groups define.
RDF need a special license , so symmconfigure cannot modify a regular FA to an RDF processor.Only EMC with a bin file can create this.
If you have already some RDF link on the boxes and if your RDF links are connected on a SAN fabric to join the other box , you can in this case by the symmconfigure process create a dynamic RDF group and create dynamic RDF relationship with your source and target volumes.
RDF from DMX2 to DMX3 could be done but you have to be aware of some warnings:
DMX2 should be at the target code 5671
DMX3 has 64K bytes per track, DMX2 has only 32K , so cylinder size of your DMX3 HVE should be half of the DMX2 HVE.
DMX2 HVE should have an even number of cylinder
