KernelVersion: v2.6.12
|
||||
Contact: Ed L. Cashin <ed.cashin@acm.org>
|
||||
Description:
|
||||
(RO) Device status. The state attribute is "up" when the device
|
||||
is ready for I/O and "down" if detected but unusable. The
|
||||
"down,closewait" state shows that the device is still open and
|
||||
cannot come up again until it has been closed. The "up,kickme"
|
||||
state means that the driver wants to send more commands to the
|
||||
target but found out there were already the max number of
|
||||
commands waiting for a response. It will retry again after being
|
||||
kicked by the periodic timer handler routine.
