Equallogic V7.1.5 intermediate snapshots

Hello,

i examined how EQL snapshots work (AoW), and think to have understood that snapshots are child only to their base volume. Nevertheless, they just store the modifications in relation to the previous snapshot...

That's why i'm in doubt it would o.k. to delete intermediate snapshots?

The system let me do so, but now i receive [ID: 4.18] ...

Could someone please elaborate on this?

Thanks in advance
