DELL R610 BIOS固件升级小记

背景

最近做的新项目，机房部署了新的评测环境，型号是DELL R610物理配置如下：

但程序报错 ERROR: This system does not support "AES".，根据过往的经验，这颗CPU是能正常运行该程序的，但在这台机器上程序拉不起来，初步判断是机器问题。检查cpu是否支持AES，如下显示不支持

# cpuid |grep -i aes | uniq
Disclaimer: cpuid may not support decoding of all cpuid registers.
      AES instruction                         = false

处理过程

去官网确认这颗CPU支持AES,并且版本与其他机器上的CPU一致。

Intel® AES New Instructions             Yes

去DELL官网查询R610的相关信息，原来主板有关于AES-NI的开关。让机房人员协助检查，确认bios里面的AES-NI的选项是开启的状态。
对比其他机器，发现这台服务器的BIOS固件是比较老的版本。

# dmidecode | grep 'BIOS Information' -A2
BIOS Information
    Vendor: Dell Inc.
    Version: 2.1.9

去官网下载对应的最新的固件，并在服务器更新。

# chmod +x R610_BIOS_60HK9_LN_6.5.0.BIN
# ./R610_BIOS_60HK9_LN_6.5.0.BIN

  The BIOS image file is successfully loaded. Do not shut down, cold reboot, power cycle, or turn off the system, till the BIOS update is complete otherwise the system will be corrupted or damaged. Bios update takes several minutes and it may be unresponsive
  during that time. Note: If OMSA is installed on the system, the OMSA data manager service stops if it is already running.

Would you like to reboot your system now?

重启系统检查bios版本并检查CPU是否已开启AES

# dmidecode | grep 'BIOS Information' -A2
BIOS Information
    Vendor: Dell Inc.
    Version: 6.5.0
    
# cpuid |grep -i aes
Disclaimer: cpuid may not support decoding of all cpuid registers.
      AES instruction                         = true

重新拉起程序并正常运行，至此，问题解决。
