> -how much bytes are 1 cyl? It depends on the physical disk geometry. For a 3380, there are 150 4K pages per cylinder, for a 3390, 180 4K pages. So, on a 3390 (the most common), 1 cyl is approximately 738K (737280 bytes).

I think I read somewhere that more recent versions of DIRMAINT now understand allocation in MB, but I could be wrong. If not, use the value above to divide the amount of swap you want in bytes by the number of bytes in a cylinder and round up. -- db
