33. Upgrade

Esxcfg-upgrade (esx2.x upgrade to esx3.x)

two. to change the service Console IP by using a command

Change the IP address of the service console under the CLI, note the case, VMware is the physical NIC virtual into Vmnic, vmnic on the creation of Virtual Switch vswitch, is the network card as a switch to use, not the network card IP address settings, Can only be created on Vswitch interface is vswif, IP settings for vswif

1. Create a service Console using the CLI

[Email protected] root]# esxcfg-vswitch-a vSwitch0 #创建vSwitch0

[[email protected] root]# esxcfg-vswitch-a "Service Console" VSwitch0 #在vSwitch0上创建Portgroup, named Service console

[Email protected] root]# esxcfg-vswitch-l vmnic0 vSwitch0 #将vmnic0绑定在vSwitch0

[[email protected] root]# esxcfg-vswitch–l #可以看到service console is already bound vmnic0

Switch Name Num Ports used Ports configured Ports MTU uplinks

VSwitch0 5 Vmnic0

PortGroup Name VLAN ID used Ports uplinks

Service Console 0 1 vmnic0

[Email protected] root]# esxcfg-vswif-a vswif0-p "Service Console"-I 192.168.1.1-n 255.255.255.0

#创建vswif0并与service console bindings, the IP address in ESX can only be tied to VSWIF0, which is the interface of the virtual switch

[[email protected] root]# esxcfg-vswif–l #可以看到Service console IP has been configured to VSWIF0

Name Port Group IP Address Netmask broadcast Enabled DHCP

vswif0 Service Console 192.168.1.50 255.255.255.0 192.168.1.255 true False

[Email protected] root]# esxcfg-vswitch–l

Switch Name Num Ports used Ports configured Ports MTU uplinks

VSwitch0 5 Vmnic0

PortGroup Name VLAN ID used Ports uplinks

Service Console 0 1 vmnic0

[[Email protected] root]# service mgmt-vmware Restart #重启服务, where you can normally use VI to connect to ESX

--------------↓ If you accidentally configure the error to delete, please see below ↓---------------

[[email protected] root]# esxcfg-vswif–l #vswif0代表的虚拟网卡的interface0, service console corresponds to VSWIF0

Name Port Group IP Address Netmask broadcast Enabled DHCP

vswif0 Service Console 192.168.1.1 255.255.255.0 192.168.1.255 true False

[Email protected] root]# esxcfg-vswif-d vswif0 #删除vswif0

[Email protected] root]# esxcfg-vswitch-l

Switch Name Num Ports used Ports configured Ports MTU uplinks

VSwitch0 5 Vmnic0

PortGroup Name VLAN ID used Ports uplinks

Service Console 0 1 vmnic0

[Email protected] root]# esxcfg-vswitch–d "Service Console" VSwitch0 #删除vSwitch0上面portgroup

[[email protected] root]# esxcfg-vswitch–d "VM Network" VSwitch0

[Email protected] root]# esxcfg-vswitch-d vSwitch0 #删除vswitch0

[Email protected] root]# esxcfg-vswitch–l #之前操作删除了vswitch信息, is now blank

Switch Name Num Ports used Ports configured Ports MTU uplinks

PortGroup Name VLAN ID used Ports uplinks

2. If not, check the following configuration file.

[Email protected] root]# vi/etc/sysconfig/network #这里纪录主机名字和网关

Networking=yes

Hostname=vi3

gateway=192.168.251.12 #网关

Gatewaydev=vswif0 #网关指定在vswif0

[Email protected] root]# vi/etc/sysconfig/network-scripts/ifcfg-vswif0 #看看这里的信息是否跟之前配置吻合

DEVICE=VSWIF0 #之前把service cosole associated with vswif0

macaddr=00:50:56:43:a3:52

PORTGROUP=PORTGROUP6 #这里的protgroup与service Console Consistent

Bootproto=static

broadcast=192.168.251.255

ipaddr=192.168.251.60 #与service Console Consistent

netmask=255.255.255.0

Onboot=yes

If the above inconsistencies, you can manually change

In the VI editor, the I key is insert mode, the text changes, the ESC key exits the Insert mode: Wq Save and exit.

Edit complete reboot. The display address may be different from the settings after startup, but you can use VI to connect to ESX

FIX: If you only want to modify the service console IP, you can execute the following command directly:

Esxcfg-vswif-i xxx.xxx.xxx.xxx vswif<x>
