主题： Re: [Disksim-users] Why does controller_bus_ownership_grant problem happen?
Hi,
In the manual of DiskSim, there is limitation of device per bus: "A bus can have
no more than 15 disks or controllers attached to it.".
In this case, there are 20 disks per bus. One alternative is that partitioning
the disks into several groups, then connect them.
