Add vCenter and ESX server hosts to the management console

Backup and DR Service usesVMware vSphere storage APIsdata protection to
create backups of VMware VMs, placing backups either in the snapshot pool
of the backup/recovery appliance or in OnVault pools.
To make API calls, the backup/recovery appliance needs to connect to the
vCenter or ESX server host with a username and password that has authority to
perform the required actions. This page explains how to add a vCenter or ESX
server host in the management console.
Backup and DR Service establishes a secure connection with the vCenter. If a
secure connection is not established, backup and restore jobs fail.
The connection to vCenter fails in either of the following scenarios:
If there is a mismatch between the name of the vCenter and the name in the
vCenter certificate.
If the vCenter certificate is not trusted by OS trust anchors or if
vCenter has self-signed certificates.
Add a new vCenter or ESX Server host
Use these instructions to add a new vCenter or ESX server host to the management console:
ClickManage>Hosts.
Select+ Add Host.
In theNamefield, enter thefully qualified domain nameof the vCenter host.
Ensure that the name in the host'sNamefield is the same as in the vCenter certificate.
The connection fails if there is a mismatch.
Optional: In theFriendly Namefield, enter a user-friendly name for the host.
The name of a host must start with a letter, and can contain letters
and digits (0-9). Do not underscore (_) characters in hostnames.
You can also add a friendly name for the vCenter host in theFriendly Namefield.
Enter the IP address of the host inIP Address. Click+to add
multiple IP addresses.
In theAppliancessection, select one or more appliances that serve this host.
If the list is long, you can use the search field to find a specific appliance
or group of appliances.
InHost Type, select eithervCenterorESX Server.
Select the data transport mode, eitherNFSorSAN. NFS is the
recommended and default setting. Enter the username and password to
connect to the host and then use theTestbutton to validate them.
You only need to enter a port if a non-standard port is being used.
