Connecting a host to two different arrays

Question

Hello,

I have a requirement to test migration between san's from different vendors, in this case it is from a clariion cx700 and an hds ams 2100, both arrays are on the same fabric. I am just wondering if there are any issues, or gotchas that would possibly occur if I were to zone the host in to both arrays? The idea would be to zone one hba to one array and the other hba to the other array.

If anyone has any experience or suggestion on the best way to achieve this, that would be great. I just don't relish the idea of backing up luns on one array, disconnecting the storage from the host, then zoning it into the new array and restoring the data.

Thanks in advance,

Cheers,

Tim.

At this stage, I was just thinking about stopping any applications running, copy the data between the luns presented from both arrays to the host, and then remove the source array, chnage the drive letter on the new luns, and then bring up the application again. I've not done this before, so not quite sure as to the best way to proceed.

i had hosts connected to HDS (tagma) and CX/DMX at the same time, both HBAs, running HDML and PowerPath at the same time. No issues. How were you going to migrate the data between two arrays ?

unfortunately, no, not in this case mostly win2k3 servers no clusters

How did you zone in both hba's? did you just create two zones and add the same wwns/hba's to each one?

Thanks again for all your help so far!

that will work, if you have systems running some flavor of unix you could mirror the data over to the new LUNs using internal logical volume manager. Any clusters ?

just regular zones, for example your typical Clariion zoning:hba1 - SPA1/B1hba2 - SPA0/B0and then HDS zoninghba1 - Tagma-port0hba2 - Tagma-port1
