QLogic HBA drivers
Locate the line for your FibreChannel Adapter device driver in the pcitable file
and then add the following options inside the double quotes:
ql2xmaxqdepth=16 qlport_down_retry=10 ql2xloginretrycount=30
ql2xfailover=0 ql2xlbType=1 ql2xautorestore=0xa0 ConfigRequired=0
If you had previously enabled QLogic failover in the file, be sure to set the
ql2xfailover option to 0. Also remove the comment character (#) if it appears
at the beginning of the line.
For example:
0x1077 0x2432 qla2xxx qla2xxx-8.02.11 "ql2xfailover=0 ql2xmaxqdepth=16
qlport_down_retry=10 ql2xloginretrycount=30 ql2xlbType=1 ql2xautorestore=0xa0
ConfigRequired=0" QLogic 2432 Fibre Channel Adapter
Emulex HBA drivers
Locate the line for your FibreChannel Adapter device driver in the pcitable file
and then add the following options inside the double quotes:
lpfc_nodev_tmo=28 lpfc_lun_queue_depth=16 lpfc_discovery_threads=32
Also remove the comment character (#) if it appears at the beginning of the line.
For example:
0x10df 0xfe00 lpfc lpfc-8.2.0.22_p1-3 "lpfc_nodev_tmo=28
lpfc_lun_queue_depth=16 lpfc_discovery_threads=32" LP11000 Fibre Channel Adapter
Update the multipathd file
On Red Hat systems, you will need to add the ulimit parameter to the /etc/
rc.d/init.d/multipathd file. Locate the start() function in the file and add
the following line:
ulimit -n 4096
Following is an example of the updated file:
start() {
test -x $DAEMON || exit 5
echo -n $"Starting $prog daemon: "
ulimit -n 4096
