Esxi 主机升级步骤

VMWare群集主机升级UEFI(BIOS)维护步骤:

1、关停群集DRS

2、迁出需维护主机的所有运行中虚拟机到群集其他主机

3、主机进入维护模式

4、带外升级固件

5、升级完成确认版本及硬件等状态

VSAN 相关指令

语法格式:vsish [参数]

常用参数:

ls    显示所有的节点信息
set    设置vc配置

参考实例

获取内存映射表:

[root@linuxcool ~]# vsish -e ls /userworld/cartel/%pid/mem/mmaps

启用Procfs:

[root@linuxcool ~]# vsish -e set /config/User/intOpts/UserProcEnable 1

触发ESXi紫屏:

[root@linuxcool ~]#vsish -e set /reliability/crashMe/Panic

修改vsan 并发数据同步进程数量:

[root@linuxcool ~]# vsish -e set /vmkModules/vsan/dom/MaxNumResyncCopyInFlight 30

验证vsan 并发数据同步进程数量:

[root@linuxcool ~]# vsish -e get /vmkModules/vsan/dom/MaxNumResyncCopyInFlight

虚拟网卡添加失败问题

When a VM-Portgroup gets a VMKernel, it isn't available anymore for VMs.

Therefore you have to distinguish between VM-Portgroups (Networking for virtual Machines) and VMKernel-Portgroups (Networking for VMKernels).

While this is true for Standard vSwitches, on a Distributed Switch you can put VMKernels and VMs onto the same Portgroup.
