scsidev builds a list of devices on your SCSI busses and creates device nodes to access them. The names are built based on their path, which is a 4-tuple consisting of the host adapter number, the channel number, the SCSI target ID, and the Logical Unit Number. Names build this way are much more persistent than the enumeration scheme used by the kernel (1st disk = sda, etc.). scsidev remembers the permissions of disappeared devices and restores the permissions properly when devices reappear. Optionally, it can create the devices as symbolic links to the main device nodes in /dev/, create missing device nodes, and handle missing permissions on the /dev/ nodes. You can assign alias names based on various pieces of information, such as vendor and model name. It also supports retrieving the serial number, the WWID, and the HSV OS ID and allows assigning names based on this information, thus providing a unique identification.
