Hotpluggingkeep the state of the operating s ystem updated when pluggable hardwaredevices are added or removed.h otplug script runs all the scripts in / etc / h otplug.d (the default isdefault. h otplug ) which in turn starts the appropriate agent listed in

S CSI DevicesS CSI Devices

Types of S CSI devicesan 8-bit interface with a bus that supports 8 devices,a 16-bit interface (WIDE) with a bus that supports

16 devicesSCSI devices are uniquel y identified using a set of 3 numbers called the S CSI I D:

the SCSI channel (Each SCSI adapter supports one

data channel)the device ID number (jumpers on the disk)the logical unit number LUN
