本文将指导我们执行升级和降级在 HP 硬件上运行的 Emulex Converged Network Adapters 固件版本的步骤

在本文中，我们使用的是 FlexFabric 20Gb 2 端口 650FLB 适配器。

检查HPKnife 片机中安装的 NIC 适配器类型

# dmidecode |grep  'NIC'
HP BIOS NIC PCI and MAC Information
        NIC 1: PCI device 06:00.0, MAC address 00:17:A4:77:00:02
        NIC 2: PCI device 06:00.1, MAC address 00:17:A4:77:00:04

                NIC.FlexLOM.1.2
                HP FlexFabric 20Gb 2-port 650FLB Adapter - NIC

                NIC.FlexLOM.1.4
                HP FlexFabric 20Gb 2-port 650FLB Adapter - NIC
                NIC.FlexLOM.1.5
                HP FlexFabric 20Gb 2-port 650FLB Adapter - NIC
                NIC.FlexLOM.1.6
                HP FlexFabric 20Gb 2-port 650FLB Adapter - NIC

检查 NIC 卡上当前安装的固件和驱动程序版本

# ethtool -i eth0
driver: be2net
version: 10.7.110.29
firmware-version: 10.7.110.34
bus-info: 0000:06:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: no

如你所见，我的固件版本是 10.7.110.34 而网卡的驱动版本是 10.7.110.29
这套固件和驱动来自HP SPP 2014.04，所以我们先把固件降级到SPP 2014.04

SPP 2014.04 可用的 CNA 固件版本为“hp-firmware-cna-emulex-2014.02.02-1.1.x86_64.rpm”

降级网卡固件的步骤

在某些 Linux 变体（例如 SuSE Enterprise Linux 节点）上，需要启用套件下方的来执行 NIC 降级。
可以从相应的 SPP iso 镜像中收集此启用套件。

注意：HP-CNA-FC-Emulex-Enablement-Kit 依赖于两个另外的 rpm，如下所示

# rpm -Uvh /tmp/libnl-1.1-49.18.x86_64.rpm /tmp/libHBAAPI2-2.2.7-0.7.33.x86_64.rpm /tmp/HP-CNA-FC-Emulex-Enablement-Kit-10.7.110.34-1.sles11.x86_64.rpm
warning: /tmp/HP-CNA-FC-Emulex-Enablement-Kit-10.7.110.34-1.sles11.x86_64.rpm: Header V3 RSA/SHA1 signature: NOKEY, key ID b1275ea3
Preparing...                ########################################### [100%]
   1:libHBAAPI2             ########################################### [ 33%]
   2:libnl                  ########################################### [ 67%]
   3:HP-CNA-FC-Emulex-Enable########################################### [100%]

接下来安装 CNA 固件 rpm

# rpm -Uvh /tmp/hp-firmware-cna-emulex-2014.02.02-1.1.x86_64.rpm
Preparing...                ########################################### [100%]
   1:hp-firmware-cna-emulex ########################################### [100%]

与任何其他 rpm 不同，上述命令不会完全安装固件，而是只会将 rpm 内容提取到其各自的位置。

固件rpm内容如下

# rpm -ql hp-firmware-cna-emulex-2014.02.02-1.1
/usr/lib/x86_64-linux-gnu/hp-firmware-cna-emulex-2014.02.02-1.1

/usr/lib/x86_64-linux-gnu/hp-firmware-cna-emulex-2014.02.02-1.1/reference.xml
/usr/lib/x86_64-linux-gnu/hp-scexe-compat
/usr/lib/x86_64-linux-gnu/hp-scexe-compat/CP025738.scexe

# cd /usr/lib/x86_64-linux-gnu/hp-firmware-cna-emulex-2014.02.02-1.1
# unzip elxflashStandalone-linux-10.2.477.23-1.zip
# cd elxflashStandalone-linux-10.2.477.23-1/lx

接下来执行以下命令开始降级

# ./elxflash.sh /ucna /sysfs  /f

elxflash: All required firmware and/or boot code downloads succeeded - Return Code=0

请重新启动系统以激活新固件。

所以脚本成功执行，返回代码为“0”

新固件版本如下所示

# ethtool -i eth0
driver: be2net
version: 10.7.110.29
firmware-version: 10.7.110.34 [10.2.477.23]
bus-info: 0000:06:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: no

注意：需要重新启动才能激活新固件

更新 NIC 固件的步骤

当前安装的固件

# ethtool -i eth0
driver: be2net
version: 10.2.477.6
firmware-version: 10.2.477.23
bus-info: 0000:06:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: no

所以当前安装的网卡驱动版本为10.2.477.6，固件版本为10.2.477.23，来自SPP 2014.04

让我们将网卡更新为 HP SPP 2014.04 的固件版本，例如：“hp-firmware-cna-emulex-2014.02.02-1.1.x86_64.rpm”

安装rpm

# rpm -Uvh /tmp/hp-firmware-cna-emulex-2014.02.02-1.1.x86_64.rpm
warning: /tmp/hp-firmware-cna-emulex-2014.02.02-1.1.x86_64.rpm: Header V3 RSA/SHA1 signature: NOKEY, key ID b1275ea3

rpm的内容如下

/usr/lib/x86_64-linux-gnu/hp-firmware-cna-emulex-2014.02.02-1.1

/usr/lib/x86_64-linux-gnu/hp-scexe-compat
/usr/lib/x86_64-linux-gnu/hp-scexe-compat/CP029026.scexe

请按照以下步骤执行更新

# cd /usr/lib/x86_64-linux-gnu/hp-firmware-cna-emulex-2014.02.02-1.1

# ls -l

因此更新已成功完成，退出代码为 1，这意味着需要重新启动才能激活新固件

或者也可以在我们使用以下步骤进行降级时完成更新
