Move data on another controller

maillon133 — Fri, 26 Aug 2011 08:34:06 GMT

Hello,

I want to know if it's possible to move quickly volumes (contains Luns) on another controller (on dataontap v8) ? I would move 5To.

I believe there are datamotion for volume (but only on the same controller) and datamotion for filer (but i'm not sure).

Someone can help me ?

Thank you.

Regards,

HI,

One way of migrating a volume from one filer to another is:

If you are using MEI product DFM, then you can use the space management wizard from NMC to migrate the volume from aggr of one filer to aggr of another filer.

But you will have to remove the exports or LUN maps before doing this.

Here in this example my source filer is sin and destination filer is seawasp:

One more way is,

IF you have volume on vFiler then you can migrate the vFiler from one filer to another.

Create a mirror of your volume from source filer to destination, break the relationship and use the volume on destination (You will have to remap LUNs or export the volume from destination to use it).

Thanks,

Arun

I would also chime in here that ONTAP 8 supports a true cluster mode. The feature your are requesting is actually the number one selling point of C-Mode. Vservers can be migrated throughout the cluster easily with no outage, taking all volumes, luns, exports, IP addresses (LIFS) with them. If this is a key requirement for you you should check out C-mode.

HI,

Please note, the first option and third option are not non disruptive unlike NDVM.

Only the second option of vFiler migration you have an option of online migration (in DFM) which is non disruptive.

Thanks,

Arun

HI Arun,

I have to partly disagree here. C-Mode Vserver migrations are non-disruptive provided that you are currently running ONTAP 8.x in C-Mode, which is probably not the case here. But as you have said Data Motion is the best way to go here, but it would require some pre-work to get the target data into a vFiler. Also he should be aware that Data Motion (vFiler migration) is not allowed between members of a cluster so you will need to move the data to a different cluster (or do a cf disable to temporarily allow it).

Cheers

Jeff

Hi Jeff,

I was only talking about 7 mode. In 7 mode the only non disruptive way to move a vol that I could think of was via the vFiler. Ofcourse if the customer plans to use cmode then what you are saying is absolutely right. Infact, thanks for pitching in and providing that information.

Thanks,

Arun

Sorry for the nit-picking! My statement was more of a teaser than an actual suggestion for this particular problem.
