一、提问

Solaris下如何修改HBA卡连接模式

二、解决方法

步骤一：备份配置文件：

# cp /kernel/drv/lpfc.conf /kernel/drv/lpfc.conf.bak 

注意：Emulex卡为lpfc.conf配置文件，Qlogic为qlc.conf配置文件。

步骤二：修改配置文件：

# vi lpfc.conf

……

# topology: link topology for initializing the Fibre Channel connection.

# 0 = attempt loop mode, if it fails attempt point-to-point mode

# 2 = attempt point-to-point mode only

# 4 = attempt loop mode only

# 6 = attempt point-to-point mode, if it fails attempt loop mode

# Set point-to-point mode if you want to run as an N_Port.

# Set loop mode if you want to run as an NL_Port.

topology=4;

……

将topology=0修改为topology=4，为将HBA卡连接模式修改为loop only.

说明：与存储直连时将HBA连接模式修改为loop only，通过光纤交换机连接存储时将HBA卡连接模式修改为point-to-point；

步骤三：重起主机生效

#reboot
