Snapmirror stuck at 100gb in 7 Mode


Hi All,


I know this question has been in this discussion forum but it didnt help me out.


I have tried breaking and resyncing the relationship but still it gets stuck at 100 gb and even sometimes it shows restart at checkpoint.


Tried every possible way to fix this and even logs did not have much info.


Can it be a network issue?


Can anyone help here






We had this happen on volumes in the past. Turned out to be an IDS device dropping packets that it didn't like.


The workaround was enabling compression on the snapmirror relationship in question. At least back then tricked the IDS into allowing it through.


Enable compression in 7-mode




we had the same problem here, you need to exclude the storage IP adresses from IDS scanning.

Compression just changes the pattern of the data stream, excluding is the way to go.



Still unable to fix this.

can anyone help
