Can we split clone pair in DMX-4 5773 code
I am cloning from R2 device.
0478 is RDF2+Mir
0EAF is BCV+R-5 ( clone targer)
R1 and R2 pair is split.
Clone pair is in copied state.
When I try split clone pair using DG, symclone -g clone_test_dg split, it gives the following error message.
"Cannot perform the operation because the device is not in a valid state"
Could you please let me know where I am wrong. I obsered client is using script for anothe device group, it works fine.

Hi Yere,
Hope you are doing well. do you have R1 or R2 local invalids? Did you use -precopy option while creating the session?

Hey Saurabh,
Thanks I am doing good, how are you.
We don't have invalids, but clone session is created with precopy option
as mentioned. Client is using script below are the steps in the script.
1. Create clone session with precopy.
2. Once precopy is at 100%, split R1 and R2 ( I guess this step is
not required)
3. Activate clone session.
4. Once session status is copied, next step clone session split.
As per the script it was happened all these days, only from yesterday we
are facing this issue. I tried the same procedure manually without
script, but unable to split
Thanks & Regards ,

ok, paste the TF query and SRDF query output. If possible, capture the debug while spliting the clone and send it to me. Send it to my gmail

Can we disable "Prevent Automatic RDF Link Recovery" option for RDFG
group on 5773 with SE 7.1.
D:\dmx\sdt24dbho2_dg>symrdf -sid 301 -rdfg 21 set rdfg
-autolink_recovery on -both_sides
'rdfg': Invalid keyword.

Hi
1. Create clone session with precopy.
2. Once precopy is at 100%, split R1 and R2 ( I guess this step is not required)
3. Activate clone session. ==> Activating the clone session will normally make your target clone device as RW and host can access the target clone LUN. Why we need step 4?
4. Once session status is copied, next step clone session split. ==> Your clone session should be in restored state if you want to perform Split. You can't split the clone session when it is in copied state.
Correct me if I am wrong.
Thanks

Thanks Govind, I did it manually by moving the RDF pairs, deleting the
RDF group and re creating RDFG group with auto link recovery option.
