Is there a way to re-create clone session after restore

well ..i got my answer from support. Unfortunately there is no way to incrementally re-create clone session. Once clone has been restored to it's source device, you have to terminate the session in order to create a new session. Once you terminate the session DMX stops tracking changed tracks and you have to do a full sync again. He recommended that i use BCV for what i am trying to do , but with BCV's i would have to wait for full sync to finish before i can use them where clones are available immediatly.

i believe you can resume the clone session incrementally after a restore. make sure to split the clone before you resume.

unfortunately there is no way to re-create clone session after restore, i tried many different combination including split ...they only way is to terminate after restore, but then it's a create/activate ..so full synch again.

i did try that ..it says device is not in correct state.

it works for me. see below output

abbott# symclone -g test_dg restore -tgt

thats exactly what i need. this is stange i am doing exactly the same thing you are doing except i am not using establish ..i first create my session and then i activate it. whats the difference ?

jyCG,

thank you very much for posting your examples. So i decided to try using establish without activate and it worked exactly how i wanted it to. First of all i nevered used -tgt option when adding STD devices to device group, this is very helpfull as now i don't have to specify each device when i operate on device group. Ok .. so first i added my target device like this:

symld -g testvg add dev 08B2 CLN001 -tgt -sid XXX

next i had to run establish (where before i had to use two separate commands ..i used to first do: symclone -g testvg create -copy -diff DEV001 sym ld CLN001 and then symclone -g testvg activate DEV001 sym ld CLN001. Now all i had to do was this:

$ symclone -g testvg establish -tgt  -full
 
Execute 'Clone Full Establish' operation for device group
'testvg' (y/) ? y
 
'Clone Full Establish' operation execution is in progress for
device group 'testvg'. Please wait...
 
'Clone Full Establish' operation successfully executed for device group
'testvg'

when this completed the state was :

$ symclone -g testvg query

     . = The Clone session is not a differential copy session.
(P): X = The pre-copy operation has completed one cycle
     . = The pre-copy operation has not completed one cycle

at this point i decided to do a re-create (incremental establish)..before i had to run symclone -g testvg recreate DEV001 sym ld CLN001, but this time i just ran:

$ symclone -g testvg establish -tgt
 
Execute 'Clone Incremental Establish' operation for device group
'testvg' (y/) ? y
 
'Clone Incremental Establish' operation execution is in progress for
device group 'testvg'. Please wait...
 
'Clone Incremental Establish' operation successfully initiated for device group

Now i decided to try incremental restore:

$ symclone -g testvg restore -tgt
 
Execute 'Incremental Restore' operation for device group
'testvg' (y/) ? y
 
'Incremental Restore' operation execution is in progress for
device group 'testvg'. Please wait...

after that completed the status was:

(P): X = The pre-copy operation has completed one cycle

Next thing i had to split:

$ symclone -g testvg split -tgt
 
Execute 'Clone Split' operation for device group
'testvg' (y/) ? y
 
'Clone Split' operation execution is in progress for
device group 'testvg'. Please wait...
 
'Clone Split' operation successfully initiated for device group
'testvg'.

and then establish, which performed an incremental establish (exactly was i was looking for)

$ symclone -g testvg establish -tgt
 
Execute 'Clone Incremental Establish' operation for device group
'testvg' (y/) ? y
 
'Clone Incremental Establish' operation execution is in progress for
device group 'testvg'. Please wait...
 
'Clone Incremental Establish' operation successfully initiated for device group
'testvg'.

a few seconds later the state was back to Copied. This is working exactly like i wanted, so how is this process different from using create/activate instead of establish ?

Thanks jyCG ..hopefully this will help somebody else.

You can recreate "incrementally" only if you created the session with the -diff option. The "establish" is a create with -diff and -copy enabled

i've been able to recreate without issues to do a regular re-sync ..it's being able to recreate after a restore ..that's what's been not working ..even though i do use -copy -diff when i create my sessions. I like using establish anyway ..one less command in my scripts . Stefano ..when you are bored one day ..can you try this process on your array and see if you get the same thing:

1) create session by using symclone -g testdg create -copy -diff DEV001 sym ld DEV002
2)activate session by using symclone -g testdg activate DEV001 sym ld DEV002
3) restore from DEV002 by using symclone -g testdg restore DEV001 sym ld DEV002
4) split session by using symclone -g testdg split DEV001 sym ld DEV002

and now the part that's been bugging me for a month now ..try to do a recreate .

5) symld -g testdg recreate DEV001 sym ld DEV002

I am curious if you get the same error message i get "Device is not in correct state"

Dynamix .. I was bored .. and here 's the results

Stefano,

thank you for doing this ..let me go through this process again ..i must be doing something stupid

How ?

Do I need to add new device to same group and then start restore ?
