Non Replication issue
Hello everyone.
I have a customer with two celerra boxes replicating on two file systesms, or so they thought. The two machines have not been communicating for about 3 weeks now and they would like to get rid of the file system that the replication is/was on. The issue is I cannot get rid of the replication or the file system as the sys ad tried to delete and the job was hung up because of no response from the DR box. Is there a way I can stop the replication without needing the machines to talk first? I would then delete the file system, make sure the machines can talk, and reset this again. Any advice would help. Thanks in advance.

Try the force flags of nas_replicate
Sometimes a data mover reboot helps with stuck replications
If not - open a service request and let customer service help cleanup

Hi,
It looks as if earlier you tried to delete the replications however the tasks got hung.
Could you login to the CLI and have a check on the following command:
nas_task -l
It may show some of the tasks in running status.
if the replication delete task is still running its in a hung state.
try aborting the hung task using the command:
nas_task -abort mover server_2
if it shows OK then it should have aborted and you can try deleting the sessions again.
if it doesnt abort, contact the support to remove the task from DM cache ans delete the sessions from both source and destination.

For next time (I'll assume support cleaned up the resulting hung task and deleted the sessions for you by now), to stop and then delete a replication session between arrays that have lost communication between them, instead you will want to select the option that corresponds to only affecting the source (and not the default of both). Then repeat the same steps with the other half of the session but on the peer array. From the CLI, the relevant options are:
nas_replicate
-stop -mode source (and not the default: both)
-delete -mode source (and not the default: both)
From the GUI when selecting Stop and Delete, you will see options corresponding to modes mentioned above.
