ESXI升级或降级HBA驱动

光纤交换机配置正常，存储能认到ESXI主机的WWN号，存储映射也正常，但是ESXI无法认到存储，创建VMFS。ESXI上HBA显示也正常，能看到WWN号

可能和ESXI上HBA的驱动有关，检查vmware的兼容性列表，16GB的HBA设置成8GB后也不行。查看对应的ESXI版本和对应牌子的HBA的驱动兼容性

1. 查看HBA设备
   通过SSH登录到esxi
   [root@ESXI03:/tmp] esxcfg-scsidevs -a
   vmhba0 lpfc link-up fc.20000090faa496b7:10000090faa496b7 (0000:95:00.0) Emulex Corporation Emulex LPe12000 8Gb PCIe Fibre Channel Adapter
   vmhba1 lpfc link-up fc.20000090faa496bc:10000090faa496bc (0000:11:00.0) Emulex Corporation Emulex LPe12000 8Gb PCIe Fibre Channel Adapter
   vmhba2 lsi_mr3 link-n/a sas.500605b00ac00080 (0000:07:00.0) Broadcom MegaRAID SAS Invader Controller
2. 查看HBA驱动版本
   [root@ESXI03:/tmp] vmkload_mod -s lpfc |grep Version
   Version: 12.8.351.29-1OEM.670.0.0.8169922
3. 重新安装驱动
   通过SCP或者TFTP工具上传下载好的驱动包到/tmp目录
   [root@ESXI03:/tmp] ls -l
   total 1224
   -rw-r–r-- 1 root root 1241976 Sep 14 06:25 VMW-ESX-6.7.0-lpfc-11.4.341.0-8102018.zip
4. 解压驱动
   [root@ESXI03:/tmp] unzip VMW-ESX-6.7.0-lpfc-11.4.341.0-8102018.zip
   Archive: VMW-ESX-6.7.0-lpfc-11.4.341.0-8102018.zip

   -rw-r–r-- 1 root root 609210 Sep 14 06:27 VMW-ESX-6.7.0-lpfc-11.4.341.0-offline_bundle-8102018.zip
   drwxr-xr-x 1 root root 512 Sep 14 06:27 doc

5. 安装驱动，用完整的路径
   [root@ESXI03:/tmp] esxcli software vib install -v /tmp/lpfc-11.4.341.0-1OEM.670.0.0.7535516.x86_64.vib
   Installation Result
