We have two hosts, FAS270 and FAS 2020. FAS 270 is using as filer and FAS2020 is using for snap mirroring(backup of FAS270). When I am trying to delete old snap shot from FAS 2020, it is showing the message "Snapshot operation not allowed on a read-only volume." How we can delete old snap shot???

SnapMirror mirrors everything from primary - including snapshots.
If you want to get rid of a particular snapshot, then you have to delete it from primary & that change will be reflected during the next SnapMirror update.

Yep, 100% true - QSM is different in that respect from VSM.
In this particular case though I believe we are dealing with VSM as the error message clearly says volume is in read-only state.
