3 Click Power Management.
4 Click Properties.
5 Enter the following information.
n
User name and password for a BMC account. (The user name must have the ability to remotely
power the host on.)
n
IP address of the NIC associated with the BMC, as distinct from the IP address of the host. The IP
address should be static or a DHCP address with infinite lease.
n
MAC address of the NIC associated with the BMC.
6 Click OK.
Test Wake-on-LAN for vSphere DPM
The use of Wake-on-LAN (WOL) for the vSphere DPM feature is fully supported, if you configure and
successfully test it according to the VMware guidelines. You must perform these steps before enabling
vSphere DPM for a cluster for the first time or on any host that is being added to a cluster that is using
vSphere DPM.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Before testing WOL, ensure that your cluster meets the prerequisites.
n
Your cluster must contain at least two ESX 3.5 (or ESX 3i version 3.5) or later hosts.
n
Each host's vMotion networking link must be working correctly. The vMotion network should also be a
single IP subnet, not multiple subnets separated by routers.
n
The vMotion NIC on each host must support WOL. To check for WOL support, first determine the
name of the physical network adapter corresponding to the VMkernel port by selecting the host in the
inventory panel of the vSphere Client, selecting the Configuration tab, and clicking Networking. After
you have this information, click on Network Adapters and find the entry corresponding to the network
adapter. The Wake On LAN Supported column for the relevant adapter should show Yes.
n
To display the WOL-compatibility status for each NIC on a host, select the host in the inventory panel
of the vSphere Client, select the Configuration tab, and click Network Adapters. The NIC must show
Yes in the Wake On LAN Supported column.
n
The switch port that each WOL-supporting vMotion NIC is plugged into should be set to auto negotiate
the link speed, and not set to a fixed speed (for example, 1000 Mb/s). Many NICs support WOL only if
they can switch to 100 Mb/s or less when the host is powered off.
After you verify these prerequisites, test each ESXi host that is going to use WOL to support vSphere DPM.
When you test these hosts, ensure that the vSphere DPM feature is disabled for the cluster.
CAUTION Ensure that any host being added to a vSphere DPM cluster that uses WOL as a wake protocol is
tested and disabled from using power management if it fails the testing. If this is not done, vSphere DPM
might power off hosts that it subsequently cannot power back up.
Procedure
1 Click the Enter Standby Mode command on the host's Summary tab in the vSphere Client.
This action powers down the host.
2 Try to bring the host out of standby mode by clicking the Power Oncommand on the host's Summary
tab.
3 Observe whether or not the host successfully powers back on.
