Chapter 9. Configuring ESX from a Virtual Center or Host > Add Host to VC
Add Host to VC
If VC is available, now is the time to add it into the system. The process is the same for VC versions 1 and 2. However, if VC is not available, all the VIC items that follow apply strictly to a host connection. VC is the main tool for managing multiple ESX Servers, and VC 2.0 can manage ESX 3 and earlier versions of ESX. It is a common interface and the only way to get access to the advanced features of ESX version 3 such as VMware HA, and VMware DRS, which are covered in Chapter 12, “Disaster Recovery and Backup.” The steps for adding into VC follow:
1. | Log in to VC. |
2. | Create a datacenter (File > New > Datacenter) and give the new datacenter a name. All hosts within a datacenter can share templates and so on. |
3. | Select the datacenter, and then add a host to the datacenter (File > Add Host). |
4. | Make the hostname resolvable by DNS. It is strongly urged that the FQDN be used; otherwise, VMware HA will have issues. It is also important that the ESX Server can ping itself and other hosts by hostname; otherwise, there can be VMware HA issues. |
5. | Enter the username and password for the root account for the host. |
6. | VC will now contact the host in question and present some information about the host, including the machine type and VMs it has. For ESX versions earlier than version 3, the next step is to configure VMotion. That is handled by other means in ESX version 3. |
7. | Next pick a location or VM folder in which to place the VMs within that host. A VM folder can be created at any time, and they are independent of hosts and are covered in Chapter 10, “Virtual Machines.” This step is new for ESX version 3. |
8. | Click Finish to add the host to VC. |
