throttle_log_
time Do not exceed
‘throttle_log_cnt’ number
of logs within this time
limit (seconds) Def = 300
Min = 5
Max = 86400 For the native mode
driver.
Works with
throttle_log_cnt.
compression_log Define how often the
compression logs are
written (in seconds)
Def = 300
Min = 5
Max = 86400 For the native mode
driver.
The driver uses this
parameter to
periodically write
status messages to the
vmkernel log. The
messages provide state
analysis on the paths,
targets, and adapter. It
differs from throttle in
that throttle stops the
driver from spamming
the logs on a very high
frequency failure.
suppress_link_
up Suppress Link Up at
initialization:
0x0 = bring up link
0x1 = do not bring up
link
0x2 = never bring up link
Def = 0
Min = 0
Max = 2 For the native mode
driver.
Enable to assist with
SAN issues during ESX
boot.
max_targets The maximum number of
discovered targets allowed Def = 256
Min = 0
Max = 4096 For the native mode
driver.
Driver parameter to
adjust supported
target count.
disable_mq Disable MultiQueue (MQ)
functionality.
0 = MQ is enabled (default)
1–16 = MQ is disabled, also
defines the number of
EQ/CQ/WQ tuples the
driver allocates Def = 0
Min = 0
Max = 16 For the native mode
driver.
By default, ESXi 5.0 ->
ESXi 5.5 has MQ
support and is the
default. Change
reflects driver
auto-configuration
feature. If the value is
nonzero, it should
match fcp_io_channel.
lpfc_delay_
discovery Delay NPort discovery when
the Clean Address bit is
cleared Def = 0
Min = 0
Max = 1 Def = 0
Min = 0
Max = 1 No changes
