I have a few issues with Snapshot/SnapMirror I would like to address with a Product Mgr.
De-swizzle or its replacement is taking an extra-ordinary amount of time, during which time no SnapMirror updates can take place. This is a definite GAP in SM as a DR/Backup solution - talking week or more
If a volume is out of space the SM/SV snapshot is rotated in the destination, but not created in the source; this causes the replication to become irreparably broken; another GAP.
SVM-DR is likewise affected by above, except that in first example, NO volumes are updated until that single volume finishes; I've had a 92TB volume take 14 days to do post processing, during which time my SVM-DR for all volumes was stopped.
I'd like to discuss issuing an RFE request, if that is still possible.
