可通过配置脚本中的 DEBUG_MODE 变量(In Srcipt Line:112)来使用debug模式,在debug模式下,不会执行选通 + 9641,9548的操作,仅执行读取传感器的操作,因此启用debug模式后需要手动配置的变量有: + i2c_bus + + + 二、服务器PCIE槽位和PCA9548的channel关系 + + 5280M7的PCIE槽位和PCA9548/9546没有确定的对应关系,取决于使用的riser卡.根据一般情况选择的Riser卡, 对应 + 情况如下: + + PCIE 0 = i2c bus 12 , 9548channel1(0x02) + PCIE 1 = i2c bus 12 , 9548channel2(0x04) + PCIE 2 = i2c bus 12 ,

= i2c bus 14 , 9548channel4(0x10) + PCIE 10 = i2c bus 14 , 9548channel5(0x20) + + 针对不同服务器产品,请对应修改server_type变量,当前支持的服务器类型: + 5280m7 + 5468m7 + + 三、M7 sysadmin用户 SSH打开方法 + + 5280M7服务器默认不开启SSH, 且串口通常有较多干扰打印, 因此推荐使用SSH来执行脚本, 刷新BMC镜像后需要重新配置 + + 1、打开M7 BMC的串口, 可通过串口线或者IPMI SOL带外登入 + + 使用IPMI SOL的前提环境: 可与BMC网络连接, 且电脑上有ipmitool工具 + SOL登陆方法: + (1) 将SOL串口源切换到BMC: + ipmitool -I lanplus -H -U admin -P admin raw 0x3c 0x2c 0x02 0x01 + (2) 打开SOL: + ipmitool -I lanplus -H -U admin -P admin sol activate + 备注: 为目标BMC的ip地址, 请自行更改为对应的ip地址 + + 2、登录进入bmc的linux系统 + + bmc linux系统的默认用户名/密码 : sysadmin/superuser + + 3、在BMC的linux系统下执行命令 + + (1) cp /etc/defconfig/ssh_server_config_with_sysadmin /etc/ssh/sshd_config + + (2) /etc/init.d/ssh restart + + 执行完毕后，就可以使用ssh登录BMC了 + + 四、常见问题 + + 1、脚本执行时出现大量的 Error + + 由于M7服务器的I2C设计有PCA9641作为I2C仲裁器, 脚本执行过程中可能会被9641强行断开I2C连接, 造成大量的 + 脚本Error, 这种情况在实际运行中是不可避免的, 直接重新执行脚本即可 + + 2、不建议使用该脚本进行压力测试 + + 由于BMC shell的版本非常原始, 没有集成高级的命令行工具, 因此处理数值时采用了复杂的脚本逻辑进行执行, 处 + 理效率较低。另外由于9641芯片的存在, 不能保证压力测试的正常执行。
