PROC_SCSI_WRITE(9) | SCSI mid layer | PROC_SCSI_WRITE(9) |
NAME¶
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
buf
length
ppos
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.
