.SH DESCRIPTION
|
||
|
|
For each
|
||
|
|
.I file
|
||
|
|
specified,
|
||
|
|
.I vblade
|
||
|
|
serves it as an AoE (ATA-over-Ethernet) target via
|
||
|
|
the specified interfaces. The default interface is
|
||
|
|
.BR /net/ether0 .
|
||
|
|
Since AoE uses raw Ethernet frames, the target is
|
||
|
|
only visible on the local ethernet segment.
|
||
|
|
.PP
|
||
|
|
All target-related options are reset for each
|
||
|
|
.IR file .
|
||
|
|
.SS Options
|
||
|
|
.TP \w'\fL-e\ \fIetherXX'u
|
||
|
|
.B -i
|
||
|
|
Initialize the configuration header in
|
||
|
|
.IR file .
|
||
|
|
All previous configuration information is lost. Without this option,
|
||
|
|
configuration is read from
|
||
|
|
.I file
|
||
|
|
and command like options override previous settings.
|
||
|
|
.TP
|
||
|
|
.B -r
|
||
|
|
Raw. Do not use a configuration header. This is useful when
|
||
|
|
exporting a device or file not generally exported by
|
||
|
|
.IR vblade .
|
||
|
|
.TP
|
||
|
|
.BI -s " n"
|
||
|
|
The exported target will have size
|
||
|
|
.IR n ,
|
||
|
|
rather than the available space in the target. A size may end in
|
||
|
|
.LR p ,
|
||
|
|
.LR t ,
|
||
|
|
.LR g ,
|
||
|
|
.LR m ,
|
||
|
|
or
|
||
|
|
.LR k
|
||
|
|
to specify a customary
|
||
|
|
.I binary
|
||
|
|
multiplier.
|
||
|
|
.TP
|
||
|
|
.BI -a " m.n"
|
||
|
|
Specify the shelf and slot (or major and minor) address of the target.
|
||
|
|
Valid shelf numbers are between 0 and 65534. Valid slots are 0-255.
|
||
|
|
.TP
|
||
|
|
.BI -c " s"
|
||
|
|
Set the AoE config string to
|
||
|
|
.IR s .
|
||
|
|
.TP
|
||
|
|
.BI -e " ether"
|
||
|
|
Listen to the network port
|
||
|
|
.IR ether.
|
||
|
|
Multiple ports may be specified.

.SH BUGS
|
||
|
|
Security depends on control of the local Ethernet segment. It may be
|
||
|
|
unwise to serve AoE on a segment bridged to a wireless network.
