This host does not currently have management network redundancy
VMware vSphere 5.0 configuration completed cluster ha in the summary bar of the host prompt "This host does not currently manage network redundancy", my environment in the server is a single NIC, nor do the redundant management network. Had to be solved by the following methods.
1. Right-click Cluster to select Edit settings.
2. Select VSphere HA and click Advanced Options.
3. Double-click in the option to enter "Das.ignoreredundantnetwarning" and double-click in the value to enter "true".
4. Click OK to exit.
5. Right-click on the host in cluster and select Reconfigure Vsphere HA.
This warning disappears when the reconfiguration is complete.

In a normal environment, you need a dual network card, in the configuration-network-vswitch0 Properties-Network adapter-add redundant network card.

The number of vsphere ha heartbeat data stores for this host is 0, less than the required number: 2
Starting with vSphere5.0, a data storage detection signal has been added to the HA function. Managing the network and storage network in my environment uses the same physical network card, so configuring the storage heartbeat is meaningless. This error occurs if you do not configure it. Fortunately, this feature can be turned off in advanced options. The method is:
1. Right-click Cluster to select Edit settings.
2. Select VSphere HA and click Advanced Options.
3. Double-click in the option to enter "Das.ignoreinsufficienthbdatastore" and double-click in the value to enter "true".
4. Click OK to exit.
5. No need to reconfigure HA, the warning will automatically disappear.

In a normal environment, 2 or more shared data stores are required.

The data store's heartbeat is useful if you have a separate storage network. There are a few options for configuring the configuration:
1. File System format
When using VMFS3, the maximum usage is approximately 2 GB and the typical usage is approximately 3 MB.
When using VMFS5, the maximum usage and typical usage is approximately 3 MB.
VSphere HA uses data storage to add less overhead and has no impact on the performance of other data storage operations.
2. Number of heartbeat data stores per host
Add this item "Das.heartbeatdsperhost" to the advanced HA option to modify the number of heartbeat data stores, and the valid range is 2~5, the default value is 2.
When configured, you will find a folder named ". Vsphere-ha" in the root directory of the data store. Be careful not to attempt to modify or delete this folder.

Note: Data storage heartbeat
When a preferred host in a vSphere HA cluster cannot communicate with a subordinate host through the management network, the preferred host uses the data store heartbeat to determine whether the subordinate host is faulted, is in a network partition, or is isolated from the network. If the secondary host has stopped the data store heartbeat, the dependent host is considered to be faulty and its virtual machine has been restarted elsewhere.
