(I haven't > really tested this heavily) can anybody please confirm/reject this? All three tools (ontape, onbar, onarchive) work fine for me. Using 7.30.FC3X5 on HP-UX 11 (64-bit) on a V2250. There are some side effects to using KAIO, but, outside of having shared memory segments locked, they're unpredictable. I would at least recommend that it be tried out instead of disregarded right out of the chute. I'm in the lucky minority in that I've never had problems with KAIO and I've always seen performance gains from using it.
