About Control Hosts in Veritas InfoScale Operations Manager
Veritas InfoScale Operations Manager uses Control Hosts as a discovery mechanism. In Veritas InfoScale Operations Manager, the Control Hosts discover the following:
Information on VMware Virtualization infrastructure (vSphere) and Hardware Management Console (HMC) server.
Agentless hosts.
To configure the Control Host on a managed host, install the Control Host Add-on on the Veritas InfoScale Operations Manager Management Server or a managed host that reports to Management Server.
Information on VMware Virtualization Infrastructure (vSphere)
In Veritas InfoScale Operations Manager, you can configure Veritas InfoScale Operations Manager Management Server or a managed host that reports to Management Server as Control Host to discover the information on the VMware virtualization infrastructure. For this configuration, you must install the Control Host Add-on on the physical or virtual hosts that you want to designate as Control Host. In Veritas InfoScale Operations Manager, you must download the Control Host Add-on from the Veritas Web site, upload to the Deployment Management Repository, and install it on the relevant physical or virtual hosts.
In your data center, Control Hosts help Management Server in discovering the following information on VMware virtualization infrastructure:
VMware vCenter servers that are configured in your data center.
VMware ESX servers that vCenters manage.
VMware Virtual Machines that are configured on the VMware ESX servers.
VMware HA Clusters.
Note:
To administer a Control Host on the Windows platform, Veritas InfoScale Operations Manager creates a user named 'vomuser' with the administrative privileges.
Ensure that the Control Hosts can ping the vCenter servers from which they can discover the information on VMware Infrastructure.
You can designate a managed host that reports to Management Server as Control Host to address the following situations:
To discover the vCenter server that is behind a firewall and you do not want to install Management Server inside the firewall.
To except Management Server from the discovery of VMware infrastructure to reduce the load on Management Server.
Discovery using the Hardware Management Console (HMC)
The HMC server manages LPAR servers and lets you discover information related to VIO servers and VIO clients. You can use the virtualization management option on the Veritas Operations Manager console to add the HMC server to Management Server.
To add the HMC server to Veritas Operations Manager, you need to install the Control Host add-on on the host where the HMC server should be added. Virtual SCSI disks on LPAR client are supported. However, NPIV, or virtual Fibre Channel disks are not supported. Currently, only Virtual SCSI disks backed by native or DMP devices are supported.
By configuring HMC server only (without the VRTSsfmh package), you can discover information about the exported storage from the VIO server to the VIO clients and the devices that are given to the VIO server from the storage area network (SAN).
Agentless discovery of a remote host
You can use Control Hosts to perform agentless discovery of VMware virtual machines. Add the vCenter server that hosts the virtual machine as an Agentless Host to the Management Server.
To perform agentless discovery of hosts, you must install the Control Host Add-on on one of the managed hosts. You can install the Control Host Add-on on Management Server, however it is not recommended as it puts extra load on Management Server.
A UNIX Control Host can only discover UNIX agentless hosts using SSH. A Windows Control Host can discover Windows agentless hosts using WMI or UNIX agentless hosts using SSH. Ensure that you install one or more Control Hosts on the appropriate platform depending on the operating system of the remote hosts you want to discover using agentless method.
For more information about agentless host discovery, see the Veritas InfoScale Operations Manager documentation.
