| 17 | .Sh NAME | |
| 18 | .Nm scsi | |
| 19 | .Nd simple program to assist with scsi devices. | |
| 20 | .Sh SYNOPSIS | |
| 21 | usage: scsi -f devicename [-d level] [-i] [-r [-b bus] [-t targ] [-l lun]] | |
| 22 | .Pp | |
| 23 | where r = reprobe, i = inquire, d = debug | |
| 24 | .Pp | |
| 25 | If debugging is not compiled in the kernel, 'd' will have no effect | |
| 26 | .Sh DESCRIPTION | |
| 27 | The | |
| 28 | .Nm Scsi | |
| 29 | program is used to give some simple commands to a scsi device. It is also | |
| 30 | really a sample usage of the general scsi commands. A more comprehensive | |
| 31 | program should be written. | |
| 32 | .Pp | |
| 33 | This program allows the operator to ask the systen to reprobe for | |
| 34 | more devices, and also to set any debug level on any scsi device. As | |
| 35 | a sample of a generic scsi command, it also can also perform a scsi | |
| 36 | .Em Enquiry | |
| 37 | command against the device against which it is openned. The | |
| 38 | reprobe can be aimed at any specific bus or target or even lun. | |
| 39 | By default it reprobes lun0 of all possible targets not yet taken. | |
| 40 | an lun of -1 will force testing of all LUNs. As a word of warning, this | |
| 41 | will override the system's caution about attaching devices not on lun0 | |
| 42 | so if a device responds to the | |
| 43 | .Em inquiry | |
| 44 | command on all luns (as many erroneously do), the system may think it has | |
| 45 | found a lot more devices, which are really just the bad luns of an existing | |
| 46 | device. | |
