Though if you choose the Unisphere route--creating a DG is the only way to do it. SE is more flexible in that respect.

Sure, but you'll find it's much easier to do so.  The syntax of some commands is very tricky without a dg.

You can use symclone -sid 1234 -file establish -full , where file.txt contains the source and target devices, separated by tabs or spaces.

Let us know if that helps!

I am not using Unisphere. In my environment i have SMC and symcli.

When i compared from other array the dg has created from host side. So i am hoping that i need make just clone relation is that correct.

Before i create a clone pair. I have verified from existing clone pair from different VMAX array. I can see the STD and BCV devices by symdev show command. But when i try to run symdg list its not showing anything.

maybe that STD-CLONE relationship was build using a device file,  that's why you don't see them in a device group.

Can you help me how to create with device file.

i am not sure what you are asking ? Use the cli, much faster/reliance and can be used with devices groups and files (as Karl described above). Devices groups can be local to a symcli host or global (GNS).

device file is very simple, for example:

2118 1DF9

where 2118 is my source device and 1DF9 is my target device, be very very careful not to mix them up or you will blow away production data.

I would highly recommend you read the TimeFinder Product Guide--this is a very good document that will explain everything you want to know about how to use TimeFinder. The first link is the product guide which gives a high-level explanation of what TimeFinder does and how it works. The second link is the the Solutions Enabler CLI guide which explains how to actually use it and run the commands:
