Need to know if there is any way by which we can achieve 'In Sync' state for sync state of replication.
I am working with UNISPHERE rest apis.
Problem is that my sync state of replication just won't achieve target 'In Sync' state from consistent state.
Let me know, if anyone knows any guidance.

Hello akfd,
You should see an in-sync state once files are synced on both systems. If you are not then, it is best to open a support case so that we can pull some logs and see why it is not going into in sync state.

Hello akfd,
Which unity system do you have and what is your current onefs version?

Hi DELL-Sam L,
Thank you for your response.
my array details are as follows:
Model: Unity 380F
There is no onefs, associated with my array.
Mine is DELL EMC Unity replication array providing replication and snapshots capability.
I want to achieve sync state as "In Sync" with my replication by performing some workaround that you may want to suggest.

Thanks @DELL-Sam L will check with support, one more request
Could you also point me to the exact difference between "consistent" and "in sync" sync states of DELL EMC Unity replication.
I know the typical definitions:
In sync: Exact replica at destination
Consistent: There is latest or point in time copy at destination.
But I could observe that even with consistent state there was no data loss and all files were copied.
Want to understand what happens at data copy level exactly in both cases.
Is it safe to proceed with just consistent state?

Hello akfd,
Here are what the different states mean. Here is a link to the Dell EMC Unity Family Configuring Replication guide & this information is found on page 42.
· Consistent – The data on the destination system is consistent from the host
perspective. The destination LUN is the latest or point in time copy of the source
LUN.
· In Sync – The data on the destination system is consistent from the host
perspective. The destination LUN is an exact copy of the source LUN.
