# lun-queue-depth [1 to 128] - The default value lpfc will use to
# limit the number of outstanding commands per FCP LUN. This value
# is global, affecting each LUN recognized by the driver, but may be
# overridden on a per-LUN basis (see below). RAID arrays may want
# to be configured using the per-LUN tunable throttles.
#lun-queue-depth=30;
lun-queue-depth=20;
# tgt-queue-depth [0 to 10240] - The default value lpfc will use to
# limit the number of outstanding commands per FCP target. This value
# is global, affecting each target recognized by the driver, but may be
# overridden on a per-target basis (see below). RAID arrays may want
# to be configured using the per-target tunable throttles. A value
# of 0 means don't throttle the target.
#tgt-queue-depth=0;
tgt-queue-depth=512;
# lpfcNtM-lun-throttle: the maximum number of outstanding commands to
# permit for each LUN of an FCP target that supports multiple LUNs.
# The default throttle for the number of commands outstanding to a single
# LUN of a multiple-LUN target is lun-queue-depth. For a target that
# can support multiple LUNs, it may be useful to specify a LUN throttle
# that differs from the default.
# Example: lpfc0t17-lun-throttle=48;
# says that each LUN on target 17, interface lpfc0 should be allowed
# up to 48 simultaneously outstanding commands.
#lpfc1t39-lun-throttle=10;
#lpfc0t40-lun-throttle=30;
# lpfcNtM-tgt-throttle: the maximum number of outstanding commands to
# permit for a FCP target.
# By default, target throttle is disabled.
# Example: lpfc0t17-tgt-throttle=48;
# says that target 17, interface lpfc0 should be allowed
# up to 48 simultaneously outstanding commands.
#lpfc1t39-tgt-throttle=10;
#lpfc0t40-tgt-throttle=30;
# no-device-delay [0 to 30] - determines the length of
# the interval between deciding to fail back an I/O because there is no way
# to communicate with its particular FCP device (e.g., due to device failure)
# and the actual fail back. A value of zero implies no delay whatsoever.
# Cautions: (1) This value is in seconds.
# (2) Setting a long delay value may permit I/O to build up,
# each with a pending timeout, which could result in the exhaustion of
# critical Solaris kernel resources. In this case, you may see a fatal
# message such as
# PANIC: Timeout table overflow
