msi-mode Controller
Specific
2 0 2 No This variable controls whether
lpfc uses MSI based interrupts
or legacy interrupts. If set to 2
(default), the driver will try to
use multiple message MSI. If
multiple message MSI is not
possible due to an OS or
hardware limitation, then the
driver will attempt single
message MSI. If single
message MSI fails, then the
driver will attempt legacy
interrupts. A value of 0
disables MSI and the driver
will use legacy interrupts.
network-on Controller
Specific
0 0 1 No This variable controls whether
lpfc provides IP networking
functionality over Fibre
Channel. This variable
is a Boolean: when zero, IP
networking is disabled; when
non-zero, IP networking is
enabled.
no-device-delay Global 1 0 30 Yes This variable (0 to 30
seconds) determines the
length of the interval between
deciding to fail an I/O
because there is no way to
communicate with its
particular device (e.g., due to
device failure or device
removal) and actually failing
the command. A value of zero
implies no delay whatsoever.
This delay is specified in
seconds. A minimum value of
1 (1 second) is recommended
when communicating with any
Tachyon based device.
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.
