>It is true that MIGRAT2 can also be on as DASD device. 

Yes, but.

MIGRAT2, by itself, is meaningless since volsers can only be 6 bytes long.

A detailed description would have helped.

PS: The first shop that I worked with HSM in had ML1 & ML2 both on disk.
And, that was back when DISK was expensive (3380-D & 3380-E).
ML2 was on the paging volumes, against my recommendations, because of cost vs 
performance issues.

Circa 1984.
