would spend determining that the disk
system is unavailable. Bus reset
signals the host to resend outstanding
I/O requests.
Bus control is restricted to the host.
4. Address High High addresses give disks high priority
on the bus, saving access time.
High addresses are needed for other
devices on the bus.
5. Bus Reset-
Hot Swap
Automatic bus reset reduces the
chances of data corruption and saves
the 30 to 60 seconds that the host
would spend determining that a disk is
unavailable. Bus reset signals the host
to resend outstanding I/O requests.
a. No bus reset reserves bus control to
the host.
b. No bus reset avoids resetting the
entire bus for one disk.
