Chapter 2 Setup Procedure for QLogic Converged Network Adapter Cards
2.4 Setting Up the Driver Parameters
*1: Recommended value = 1024 ¸ (number of FCoE ports that are connected to a single CA port) ¸ num-
ber of LUNs
(Round the result down)
- Use the value of "8" if the actual result is lower. Use the maximum value if the actual result exceeds
the maximum value for the driver.
- To achieve maximum system performance, this value can be changed according to the server load
and the peak operating times.
The number of simultaneous command executions per CA port for the ETERNUS DX is limited to
-
1024. This value is used by multiple servers that share the CA port. A maximum of 1024 commands
can be executed per CA port.
Some driver versions do not support the "ql2xfailover" and "ql2xtgtemul" driver parameters.
Use the "modinfo qla2xxx" command to check whether the "ql2xfailover" and "ql2xtgtemul" driver pa-
rameters are supported. Do not specify the "ql2xfailover" and "ql2xtgtemul" parameters if they are not
supported.
●
When the ETERNUS Multipath Driver is used
Setting driver parameters is not required.
When Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 6, or Red Hat Enterprise Linux 5 is used, com-
ment out the following two lines if they appear in the configuration file.
:
install qla2xxx /sbin/modprobe qla2xxx_conf; /sbin/modprobe --ignore-install qla2xxx
remove qla2xxx /sbin/modprobe -r --first-time --ignore-remove qla2xxx && { /sbin/modprobe -r
--ignore-remove qla2xxx_conf; }
:
Example:
•
(Before)
alias eth0 tg3
alias eth1 tg3
alias scsi_hostadapter megaraid_mbox
alias scsi_hostadapter1 ata_piix
install qla2xxx /sbin/modprobe qla2xxx_conf; /sbin/modprobe --ignore-install qla2xxx
remove qla2xxx /sbin/modprobe -r --first-time --ignore-remove qla2xxx && { /sbin/modprobe -r --ignore-r
emove qla2xxx_conf; }
alias qla2100 qla2xxx
alias qla2200 qla2xxx
alias qla2300 qla2xxx
alias qla2322 qla2xxx
alias qla2400 qla2xxx
# options qla2xxx for MPD (Do not edit this line)
options qla2xxx ql2xfailover=0 ConfigRequired=0 ql2xmaxqdepth=8
alias scsi_hostadapter2 qla2xxx_conf
alias scsi_hostadapter3 qla2xxx
alias scsi_hostadapter4 mpdh
Add "#" to the beginning of the following lines to comment them out.
install qla2xxx /sbin/modprobe qla2xxx_conf; /sbin/modprobe --ignore-install qla2xxx
remove qla2xxx /sbin/modprobe -r --first-time --ignore-remove qla2xxx && { /sbin/modprobe -
r --ignore-remove qla2xxx_conf; }
