Copy Lun to Lun

sure, use Clariion Lun migration tool, build a lun of the same of bigger size and then right click on the source lun and select migrate ...follow the wizard

actually SnapView will do that for you too, but if you did not have SnapView license but did have SAN Copy ..that would work too.

Thank-You for your answer. I didn't know about this tool. I read about it this morning. Apparently it does just what it says; Migrate. It actually moves the data and destroys the source lun afterwards. That could be handy I'm sure.

However, I am asking if there is a way to COPY the contents of one lun to another lun without mounting the luns to a host to have the host do it. Do you know of any way to do that from within the array?

We would not want to destroy the source until we know everything is ok with the destination data.

yep, check out SnapView for Navisphere Admin Guide ..sounds like Clones is what you are after, very easy to configure. I would recommend you use command line (naviseccli) instead of Navisphere ..it's so much faster that way .

I have SnapView but no San Copy. I'll figure out how to do it with SnapView. I've never used SnapView yet. I use Mirrorview and do have reserved lun pools set up. Thanks for the follow up info.

The main difference between using SnapView and SanCopy for copying LUNs is that with SnapView the Luns have to be identical sizes, but with SanCopy they can be the same or larger.

Thank you for that information.

Right now we have two arrays; production and DR. We have mirrorview and mirrorview/a installed on both arrays.

For some reason we do have SnapView installed but only on the DR Array. I am trying to make the case to install SnapView on the production array so we're even on that and to install SanCopy on both arrays as well. That way we can snap, copy and synch to our heart's content with full functionality on both arrays from and to either one.

I'm hoping that what is being said is correct and that I will have lun to lun copy functionality within the array after I get all these goodies. It would be most embarassing to not be able to do that and to have to justify something else to do it.

I'm hoping that after loading up on Mirrorview, Snapview and San Copy, I'll be pretty well set up for just about anything I will ever want to do.

Silly me. That probably doesn't even exist. Anywhere!

Thanks again.

Yep, you'll be setup for anything all right....

Differences FYI

SnapView only replicates inside the array. Mirrowview only replicates between arrays and SanCopy does both. That doesn't mean you only need SanCopy, as the other two have features SanCopy doesn't. Bottom line is you are right with all three you can do what you want.

Good Luck

some tools might be redundant ..but hey ..if the budget is unlimited ..get the toys

Be sure that you check out:

"EMC CLARiiON Open Systems Configuration Guide"

When you install SANcopy, you turn the front-end SP ports into initiators - this means that the SP ports will log into each other if the multiple SP ports are in the same switch zone (ie. one HBA and two SP ports in the same zone).

Also, you can not clone a mirror (except in release 24), you can only take a snapshot of the mirror.

Thanks for the tips Glenn, I will download that guide.

glen,

can you explain this "(ie. one HBA and two SP ports in the same zone)." . Why would somebody configure a zone with one initiator and multiple targets ? When i configured my SAN Copy zones i simply zoned two targets ( in my case CX700 SPA/Bs to DMX3 FAs)

Thanks

The term "single initiator zone" is used by EMC to describe a zone that contains one initiator (HBA) and one target (SP port).

Some people create zones with one HBA and multiple SP ports - saves entry time.

It's these zones (multiple targets) that cause problems when SANcopy is installed.
