How to create clone pair in VMAX

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:

The symclone commands don't have the preview/commit syntax of symconfigure.  When you run them, they will execute operations on the array.  I strongly urge you to look at the guide Cody recommends.  As Dynamox says, blowing away production data is very easy.  Research the guide, try it with a test device, then try it in production.

What does establish -full, Is it like commit or preview.

I can see that it is in Recoverpoint replication.

Held devices usually indicates that there is some type of replication session to that device possibly (TF, VAAI and a few others). They can also be have been manually held for whatever reason.

You can see what is held by running symdev list -held

You can unhold a device by running symdev unhold dev -sid . Note that if the hold is due to some replication or synchronization this command will also fail. The only way to unhold those devices is by determining the feature that created the hold and terminate the process

I have unhold the device and started precopy and activated the clone pair.

On recoverpoint i can see the transfer status as INT(56%)
