Dynamic SRDF to migrate host

Unfortunately it's not as simple as that.
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.

Hi,

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

I took a look at the SYMCLI document you mention and it's really misleading. It doesn't describe everything you need to do to get setup to start very clearly. There is a ton of prep work, you should EMC to look at your specific environmtent. It exceeds the scope of what a forum like this can provide.

Anyone heard of a Bug with AIX 5.2 and below, where if the ODM definitions aren't up to the latest, changing a STD device to a R1, upon reboot the host won't recognize the volumes as the originals and mark them as new, and the filesystems won't load....???? I heard it word of mouth and haven't been able to find it in primus to support the comment, so thought I would post it here..... Thanks.
