aoe – ATA–over–Ethernet (AoE) interface|
bind –a #æ /dev |
The AoE (ATA–over–Ethernet) interface serves a three–level directory
providing control and access to AoE targets. The interface provided
is primarily intended for low–level control of the AoE initiator.
See sdaoe(3) for the standard interface.|
rediscover Returns the current state of the variable named by the keyword. Writing the variable's name to the control file toggles the state of that variable.
ifn path Path to nth bound Ethernet device.
ifn ea Ethernet address of this device.
ifn flag A flag of ``Up'' indicates that this interface is available.
ifn lostjumbo Number of consecutive lost jumbograms.
ifn datamtu Incorrect and unused.
state ``Up'' or ``down''.
nopen Number of clients using this target.
nout Number of outstanding AoE frames.
nmaxout Maximum number of outstanding frames allowed.
nframes Maximum number of outstanding frames. Nframes is greater than nmaxout when the initiator is reducing the number of in–flight frames due to packet loss. It is assumed that packet loss is due to an overwhelmed target and not poor network conditions.
maxbcountMaximum number of data bytes per AoE frame. Using standard frames, maxbcount is 1024 or two sectors. AoE ATA headers are 36 bytes.
firmware The respective fields from the ATA identify unit command.
flag List of flags useful for debugging. The flag jumbo indicates that jumbo frames are accepted, not that they are being used. Maxbcount should be consulted for this purpose.
failio fail outstanding i/o.
identify send an ata identify device command to the target.
maxbno n set the maximum number of block sent per packet.
mtu n set the maximum number of bytes (including header) sent per packet.
nofail never fail this target. This is useful if your root device is on this target.
setsize n with no arguments, reset the device size to the size claimed. Otherwise, assume the device is the given size.
addr A space–separated list of the target's Ethernet addresses visible from this interface.
npkt The number of frames sent on this interface.
resent The number of frames re–sent. Frames are re–sent when they have been outstanding twice the RTT average.
flag ``Up'' when the netlink is up.
mintimer Minimum timer and RTT average as per Congestion Avoidance and Control.
nl path Path of the Ethernet device.
nl ea Ethernet address of the local Ethernet device.
nl flag ``Up'' if the local interface is up.
