1254 z/VM: CP Commands and Utilities Reference
Use SET HOTIO to change the maximum number of consecutive, unsolicited
interrupts per second that CP should allow from an I/O device (the hot I/O rate)
before refusing to accept input from it. For information on how to display the hot I/O
rate settings for your system, see “QUERY HOTIO” on page 816.
ALL
tells CP to change the hot I/O rate for all the devices in the active I/O
configuration.
DASD
tells CP to change the hot I/O rate for all the DASDs in the active I/O
configuration.
Graf
tells CP to change the hot I/O rate for all the graphic display devices in the
active I/O configuration.
rdev
tells CP to change the hot I/O rate for a device at a specific real device number
in the active I/O configuration. The variable rdev must be a hexadecimal
number between X'0000' and X'FFFF'. If you specify a real device number that
does not exist, CP issues an error message and ignores your command.
rdev1-rdev2
tells CP to change the hot I/O rate for devices in a range of specific real device
numbers in the active I/O configuration. The variable rdev must be a
hexadecimal number between X'0000' and X'FFFF'. The first real device
number in the range must be less than the second real device number;
otherwise, CP issues an error message and ignores your command. If you
specify a range of real device numbers that do not exist, CP issues an error
message and ignores your command. However, if there are some valid real
device numbers in the range, CP accepts the command.
