This post is a small TimeFinder Clone 101 doc. It will only contain some basic commands from were you can start using it. anything else or more advanced can of course be found in the manual.

Clone session using a device group

Below are the steps to create and delete a Clone copy session using a Device Group( DG ).

1 Create a Regular Device Group.

symdg create TestDg -type regular

2 Add the devices to device group.

Add the standard devices AAA( source ) and AAB( Target )to the DG. Assume this will add as DEV001 and DEV002.

symld -sid 1234 -g TestDg add dev AAA
symld -sid 1234 -g TestDg add dev AAB

3 Create Clone Session

symclone -g TestDg create DEV001 sym ld DEV002

The above command will create a clone session and also make the target device in NotReady( NR ) state.You can also add the -precopy option to start a background copy from source to target device, prior to the activation.

symclone -g TestDg create DEV001 sym ld DEV002 -precopy

4 Activate the session

symclone -g TestDg activate DEV001 sym ld DEV002

The above command will start the copy operation from sorce device to target.And also make the target device to Read/Write,thus accessable to the host.

5 Check the status of copy operation.

symclone -g TestDg query 

Once the the source device is fully copied from source to target , the state of the pair will change from ‘CopyInProg’ to ‘Copied’.

6 Break the session

symclone -g TestDg terminate DEV001 sym ld DEV002

This will terminate the clone copy session , deletes the pairing information from the storage array and removes any hold on target device.You have to ‘Terminate’ while the pair in ‘Copied’ state to get a fully valid data.
