.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
utility provides a way for administrators to control aspects of
|
||
|
|
.Xr isf 4
|
||
|
|
devices that can not be managed though the
|
||
|
|
.Xr disk 9
|
||
|
|
interface.
|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
utility takes a device name as its first argument followed by a command.
|
||
|
|
Currently supported commands are:
|
||
|
|
.Bl -tag -width erase
|
||
|
|
.It Ic erase
|
||
|
|
Erase blocks beginning at
|
||
|
|
.Ar offset
|
||
|
|
covering a total of
|
||
|
|
.Ar size
|
||
|
|
bytes.
|
||
|
|
The
|
||
|
|
.Ar offset
|
||
|
|
argument must be a multiple of 128K.
|
||
|
|
The
|
||
|
|
.Ar size
|
||
|
|
argument must either be a multiple of 128K or a number less than 32K in
|
||
|
|
which case it is treated as a number of 128K blocks to erase.
