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.?

Are you looking for below command?

symld -g <RDF1 DgName>  add dev <SymDevName of Clone target> -tgt

Hi hemachandra,

thanks for your response.i  know the command.I just want to know,is it possible to create clone

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 <RDF1 DgName> establish –full -tgt
symclone -g <RDF1 DgName> 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 <group> add dev 0BAD -tgt

Re: CAN DYN_RDF DEVICE BE SOURCE DEVICE FOR CLONE ?

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 <name> -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 <STD dev> -g <dg_name> -sid <>

# symdg add dev <RDF dev> -g <dg_name> -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..
