proc_scsi_write(9) [centos man page]

PROC_SCSI_WRITE(9)						  SCSI mid layer						PROC_SCSI_WRITE(9)

proc_scsi_write - handle writes to /proc/scsi/scsi SYNOPSIS
ssize_t proc_scsi_write(struct file * file, const char __user * buf, size_t length, loff_t * ppos); ARGUMENTS
file not used buf buffer to write length length of buf, at most PAGE_SIZE ppos not used DESCRIPTION
this provides a legacy mechanism to add or remove devices by Host, Channel, ID, and Lun. To use, "echo 'scsi add-single-device 0 1 2 3' > /proc/scsi/scsi" or "echo 'scsi remove-single-device 0 1 2 3' > /proc/scsi/scsi" with "0 1 2 3" replaced by the Host, Channel, Id, and Lun. NOTE
this seems to be aimed at parallel SCSI. Most modern busses (USB, SATA, Firewire, Fibre Channel, etc) dynamically assign these values to provide a unique identifier and nothing more. AUTHORS
