Table 11. Recommended configuration file parameters for a AMCC FCX-6562, AMCC
FCX2-6562, AMCC FCE-6460, or a AMCC FCE-1473 adapter (continued)
Parameters
QfullRetryDelay
LunRecoveryInterval
FcLinkSpeed
JniCreationDelay
FlogiRetryCount
FcFlogiTimeout
PlogiRetryCount
Recommended settings
5000: Default.
Delay (msec) before retrying after receipt of
an I/O operation with a SCSI queue full
status from a target. The number of retries is
based on the QfullRetryCount parameter.
50: Default.
Sets the LUN I/O recovery interval (in msec)
after the driver reconnects to a disk. It is a
global parameter affecting all targets, and
determines how long the driver waits after a
port is discovered until sending I/O
operations to that port. Some devices might
require more time to flush an I/O operation
that was in progress prior to a link going
down; if this is the case, increase the value
of this parameter.
3: Default.
Specifies the desired fibre-channel link speed
as follows:
v 0: default to SEEPROM setting
v 1: force 1 gigabit per second
v 2: force 2 gigabit per second
v 3: auto negotiate link speed
5: Default.
Delay (seconds) after driver creation to allow
the network to stabilize, discover ports, and
build the driver database. Increase this value
if targets are being discovered too late in the
restart process.
3: Default.
Total number of fabric login (FLOGI) attempts
before giving up logging in to a switch.
Failure prevents participation on a fabric
topology.
10: Default.
Specifies the amount of time (in seconds)
that the driver waits for a fabric login
(FLOGI) to be accepted. The value should
be increased only if the switch to which the
host adapter is connected requires more time
to respond to a FLOGI. The number of
retries is configured with the FlogiRetryCount
parameter.
5: Default.
Total number of port login (PLOGI) attempts
before failing to log in to a SCSI target.
