DEPENDENCIES

disc3

When the system is rebooted, the disc3 driver always resets the value of the

immediate_report

mode parameter to off.Ifioctl() or

scsictl is used to change the setting of immediate reporting

on a SCSI device, the new value becomes the default setting upon subsequent conﬁguration (for example,

opens) of this device and retains its value across system or device powerfail recovery. However, on the

next system reboot, the

immediate-report

mode parameter is again reset to the value of the tunable

system parameter,

default_disk_ir

. This is set using the kctune command.

sdisk

ioctl() or scsictl is used to change the setting of immediate reporting on a SCSI device, the new

value becomes the default setting upon subsequent conﬁguration (for example, opens) of this device until

the "last close" of the device, that is, when neither the system nor any application has the device open (for

example, unmounting a ﬁle system via umount

and then mounting it again via mount (see mount(1M)).

On the next "ﬁrst open", the

immediate-report

mode parameter is again reset to the value of the tun-

able system parameter,

default_disk_ir

. This is set using the kctune

command.
