Why does controller_bus_ownership_grant problem happen?</FONT></FONT></DIV>

<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>In the manual of DiskSim, there is limitation of device per bus: "A bus can have</DIV>
<DIV>no more than 15 disks or controllers attached to it.".</DIV>
<DIV> </DIV>
<DIV>In this case, there are 20 disks per bus. One alternative is that partitioning</DIV>
<DIV>the disks into several groups, then connect them.</DIV>
<DIV> </DIV>
<DIV>Lanyue Lu</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Quoting John Bucy <bucy@gloop.org >:</DIV>
<DIV> </DIV>
<DIV>> Hmm ... that assert is new to me. There may be some static</DIV>
<DIV>> limitations on the number of devices per bus, etc -- I've never been</DIV>
<DIV>> very familiar with that part of the code. Please write back when you</DIV>
<DIV>> figure it out so we know :)</DIV>
