CAN DYN_RDF DEVICE BE SOURCE DEVICE FOR CLONE ?
Hi Everybody,
I am trying to create clone of a dyn_rdf device,but i couldnot.Generally I create clone of a standard device just by creating a regular device group
and adding source and target devices.But for creating clone of DYN_RDF device ,what device group i have to create,i tried creating a RDFG1 group,because source is
a r1 device.Now should i convert clone target into RDF1 device.Please let me know procedure for creating clone of a RDF device.?

It is possible to create a clone of R1 device(Dynamic RDF Capability).
DG should be of type RDF1
clone target can be BCV or standard device.
symclone -g establish –full -tgt
symclone -g query

Create a file called say pair.txt
in this put source and target like this
0001 0002
where 0001 is the source device
and 0002 is the target device
then
symclone -sid xxxx -file pair.txt create ....
etc

yes you can, add -tgt when you add clone to RDF1 group.
symld -g add dev 0BAD -tgt

Dynamox is correct. The target device has to be added with –tgt option before creating a clone session which creates relationship with the source & target devices.
If the device not added to the device group with –tgt option, then the script will not let you to create the clone sessions.
Else the file can be used with necessary options.

Hello Srik1920,
if it is not necessary to work with device group, then you can use as SamClaret said a txt file and then you can add the source and the target devices of the clone.
Command is: symclone -sid <> -f <> create -precopy -differrential
If you are going to use device group then you have to use the -tgt parameter, but i believe that using txt file is pretty much easier.

If you query is on how to add the STD and RDF device to a DG, then
You can create a DG with the type ANY
# symdg create -type ANY
When adding the device to the DG you need to use 'symdg' command and not 'symld'
I believe this option is available from SE 7.4 and above.
# symdg add dev -g -sid <>
# symdg add dev -g -sid <>
The only implication here is that you always have to mention the source and the target while performing the operation.
This is why we use the -tgt flag which was mentioned earlier by our experts..
