Migrate HP EVA to IBM SAN

We have a lot of servers that run novell, Linux, Microsoft and they are mapped towards a HP EVA SAN storage.
 
The plan is to change the storage to any IBM SAN. So we need to migrate from HP EVA storage to another storage. if you have any migration plan. Any third party tools available. What should be the procedure for migration.

If you are migrating to IBM you probably ought to be considering IBM's version of the SVSP, its called a SAN Volume Controller (SVC) Remember once you install a SVC/SVSP you are genrally tied in to using one of these devices as although its really easy to start using these devices its really really hard to stop using them!

Are you running virtual machines or physical?

For physical machines I would shtudown all services, map the LUN from the second SAN, use a tool like robocopy to migrate data, dismount original LUN, Re-Map new LUN with old driver letter and you should be set.  This way the data is at the old location just in case.

We have some virtual machines are there. Some in vmware and some hyper-v. How about migrating them.

What the novel and linux systems. Can we use the robocopy  for the same too?

For Novell you can't but for Linux I imaging that you can use rsync.  Haven't played with Novell for 10 years, not sure what you would use.

You could also use a product like HP's SVSP to migrate the data transparently and non-distuptively... probably only cost-effective for lots of data, though.   See  hp.com/go/svsp    

(I get nervous when I hear "shut down servers" and "manual copy".... )

I asked how to migrate from HP to IBM SAN not IBM to HP.

Yes... you can use SVSP to migrate from HP to IBM, automatically and while your application continues to run.

Is possible for virtual and non virtual servers. What is the basic procedure for the migration in short.

You've got your existing LUNs... and everything is done at the LUN level with migration.

SVSP will be installed and connected to your switches.   Then you'll create new zoning maps, with the odd-numbered SVSP Fibre Channel ports of the Data Path Modules pointing to your servers, and the even-numbered ports pointing to your storage.  

Through the SVSP GUI, you configure the DPMs to present the current storage as you need it to be presented.

You then enable the new zoning map, and everything is as it was before, but data is now going through the SVSP DPM (this is not a switch, although it looks like it; it is a special-purpose appliance that has a programmable ASIC between each pair of ports so that the remapping can be done at line speed).

Then you'll create storage pools in the new system and present it to SVSP.

And last, you'll use the GUI to tell the DPMs to migrate data from the old LUNs to the new ones you just created.

SVSP will ensure that all writes go to the new LUNs.  
Reads come from the most recently-written storage, whether it's the old or new array.
And in the background, SVSP will be moving data from old to new automatically, until the new array has all of the data, and there are no longer any modifications written to the old array.

You can also use SVSP to provide functions such as mirroring of different (even different vendors') arrays, snapshots, thin provisioning, and striping data across arrays.

If you're seriously interested, spend some time reading up about it from http://www.hp.com/go/svsp
