how to create/synchronize the remote clone of a local clone ?

Hi,


we a have 2 DMX. there is a srdf link between them and a clone on the source DMX. I would like to clone on the second DMX the clone of the first DMX (not cloning the source but the clone himself). i've tried to do it but not suceeded.
1) is it possible (i've not find exactly this case in docs) ?


DMX1 DMX2
___________ _______________
SOURCE1 * <---> * SRDF1 *
^ * * *
| * * *
| * * *
BCV1 * <-???-> * BCVCLONE1 *
___________ _______________

2) how to do it ?

i've tried this:
=========

[root@>>symdev -sid 2143 show 3AB

[root@>>symclone -g GRPfamieR3 -rdf -bcv -full establish BCV001 BCV ld BRBCV001

Execute remote 'Clone Full Establish' operation for device 'BCV001'
in device group 'GRPfamieR3' (y/ ) ? y

'Clone Full Establish' operation execution is in progress for device 'BCV001'
paired with target device 'BRBCV001' in
device group 'GRPfamieR3'. Please wait...

The device must be an RDF device for this function

If I've understood you correctly, you need to convert your "BCV+R-5" (source clone) to a "RDF1-BCV+R-5".

You'll also need an identically sized RAID5 volume in the target box (this one doesn't need to be a BCV), which will become an "RDF2+R-5"

The SRDF relationship can be created in one of two ways:

1) Using "Dynamic RDF". Each of the volumes above needs to have the dyn_rdf(DRX) attribute set (via symconfigure). The SRDF relationship is then created by using the "symrdf createpair" command.

2) Using "Static SRDF". The source volume above is "converted" to "RDF1-BCV+R-5" using symconfigure, specifying the target volume ID in the symconfigure script. The target volume is automatically converted to an R2 at the same time.

I can only give an overview here. I suggest you talk with your local EMC office for in depth assistance.

Best Regards, MT

In the future, please avoid posting full output of commands .. please hide full box SN if possible.
If you want to have a copy of your data on a different box, you need SRDF.
So the answer to your question mark is a RDF link between the two devices .. :-)
There are options (Open Replicator) but since you already have RDF links between the boxes, RDF may be the easier choice :-)

what's wrong with full output of commands ? Easier to understand what the person is doing.

I simply asked to avoid posting full symm ids :-)

then you also need to ask not to post device WWN since it contains frame id in it as well ;)

Maybe I'm being naive about this, but what difference does it make if someone knows your Symm ID?

Given the symm ID I can search for open Service Request from the box ... and from the SR I can find details on the customer. Is it enough ?? :-)

you can ..customers can not. Since you work for EMC we would not expect you would do anything malicious, would you ? ;)

Who knows ;-)

Dynamox .. I know everything about you .. always remember to buy EMC storage otherwise I'll send your data to the tax office :D (hope it's scaring you too .. I'm already scared! ;) )

I didn't really know that customers can not search SR .. ThX for the tip !! :-)
