nodev-holdio Controller
Specific
0 0=Off 1=On Yes This variable controls if I/O
errors are held by the driver if
a FCP device on the SAN
disappears. If set, I/O errors
will be held until the device
returns back to the SAN
(potentially indefinitely). This
driver property is ignored, if
SCSI commands are issued in
polled mode. The upper layer
may retry the command once
the error is returned.
nodev-tmo Controller
Specific
30 0 255 Yes This variable controls how
long I/O will be held by the
driver if a device on the SAN
disappears. If set, I/O will be
held for the specified number
of seconds. If the device does
not appear on the SAN before
nodev-tmo seconds, then the
driver will fail all held I/O and
mark the device as
unavailable. The upper layer
may retry the command once
the error is returned.
num-bufs Controller
Specific
128 64 4096 No This variable specifies the
number of command buffers
to allocate. These buffers are
used for FC Extended Link
Services (ELS), and one for
each FCP command issued in
SLI-2 mode. If you want to
queue lots of FCP commands
to the HBA, then increase
num-bufs for better
performance. These buffers
consume physical memory
and are also used by the
device driver to process loop
initialization and re-discovery
activities. Important: The
driver must always be
configured with at least
several dozen ELS command
buffers; Emulex recommends
at least 128.
