Open Replicator: data migration from DS4800 to VMAX-SE
Hi,
I'd like to know if there is anybody dealing with:
1) DS4800 is not compatible with OR. Why? It's the same architecture of DS4000, I can't understand the reason.
2) Is it possible to activate a differential copy if I have to migrate from DS4800 to VMAX (pull)?
3) With hot copy the control devices are on line, but the remote devices (DS to VMAX migration)?
4) In HACMP environment on remote devices can I have cluster on line?
There is any document that deal with OR procedure when IBM DS is involved?
Thanks,
Mario

in answer to your first question
EMC supports most third party arrays with ORS however you need to have your ATC raise an RPQ for them. The reason for this is that EMC engineering want to have tight supervision of it.
I was recently involved in ORS from IBM SVC with DS8100 backend to V-Max and we had to submit an RPQ, migration went fine

Hi, sometimes it dipends on the path of remote storage if it's an actve/passive storage. Try to failover the lun on the alternate path on DS4800.

Hi,
you are right, no Supp. Matrix lists any DS4000, but if I remember I asked an RPQ for a DS4000 storage and Open Replicator. The answer was that the architecture of DS4000 is quite the same. My advice is to ask for a RPQ.

It could be an old document but I dont see DS4000 supported by ORS, do you have a document which says its supported?

Yes,
it happens. Further more you should verify the size and the geometry of source and control device, VMAX is 15 tracks per cyl with 512 bytes block.

OR often gets slow near the finish line. Probably, urs is stuck at a phantom track.

Hi,
on cold pull or push not incremental, you can use not necessary all port where your control devices are mapped and you can follow the same rule of a normal host initiator (single hba zoning).
