change qllink_down_timeout in ESX4.0 for Qlogic

Hi,

I need to set the timeout linkdown on the ESX 4.0 that has qlogic card to 10 seconds, I used the commands below, but It seems didn't work:
Request Queue = 0xbc013000, Response Queue = 0xbc094000

 

#esxcfg-module -s qllink_down_timeout=10 qla2300_707_vmw

或者#esxcfg-module -s 'qllink_down_timeout=10' qla2xxx
#esxcfg-boot -b

#reboot

 

The qllink_down_timeout value is still set to default 30.

# cat /proc/scsi/qla2xxx/4

----------------------
经笔者测试：在ESX Server4.0中，这样设置，重启后会导致qla2xxx文件夹丢失，光纤驱动加载不成功，不能再使用光纤及其挂载的资源。
解决措施如下：

#esxcfg-module -s '' qla2xxx
#reboot
----------------------
若要设置想要的参数：
#vmkload_mod -s qla2xxx
will generate a list of all parameters the module could handle.
#esxcfg-module -s 'par1=xxx par2=yyy' qla2xxx
#reboot
即可。

当然，我们也可以下载Qlogic的SANsurfer工具修改FC HBA卡的BIOS信息，笔者未测试。
