Figure 7. Two-Cluster HIT Group Managed From a Cluster
In the previous figure, assume further that you use the Add Hosts option from the ASM/ME instance on Node 1 to add Node 4
to it. If ASM/ME is not installed on nodes 4, 5, and 6, ASM first sets up the appropriate trust relationships between nodes 4, 5,
and 6. This process is indicated by the bidirectional arrows. After you add Node 4 to Node 1, you can then manage all of Cluster
B’s nodes from Node 1. However, you cannot manage any of Cluster A’s nodes from Cluster B until you add a node from Cluster
A to Cluster B.
Create a HIT Group — Overview
Use the Add Hosts wizard to create a HIT Group. With this wizard, ASM/ME automatically detects whether a clean installation
or update is required on the host that you are adding. ASM/ME automatically installs (or updates) on that host. The host is
added to the HIT Group.
If the installation or update fails, perform a manual installation on the host that you are adding. To add the other host to the HIT
Group, use the Add Hosts wizard.
Prerequisites for HIT Groups
For new installations to run successfully on remote hosts, allow incoming ping requests through the remote host’s firewall to the
remote host. Use Windows Server Manager to create new inbound rules for your firewall. Select ICMPv4 or ICMPv6 protocol
types for IPv4 and IPv6 pings, respectively. If both the local and remote hosts are in the same domain, allow the connections
over the domain profile type.
If you do not want to edit firewall rules, perform a manual installation on the host that you are adding. Use the Add Hosts
wizard on the local host to add the host to the HIT Group.
Enter username and password credentials to install Host Integration Tools on remote hosts added to the HIT Group. These
credentials are never stored and are only used for the installation. The following requirements must be met:
● If installing on a cluster, you must provide the appropriate credentials (domain user with local administrator rights) across all
of the cluster nodes.
● If adding or installing on multiple hosts:
○ Single Domain—For multiple machines that belong to a single domain, you must provide the appropriate user credentials
(domain users with local admin rights) so that ASM/ME can successfully access the machines to perform the required
installations.
○ Single Workgroup—For multiple machines that belong to a single workgroup, each machine must have the same local
admin account credentials.
○ Multiple Domains—For machines across multiple domains, add or install on all the machines from one domain at a time.
The Remote Procedure Call (RPC) service must be running. This service should start by default on Windows systems. If it is not
running, or if the firewall is blocking it, the installation will not work.
If you use the Browse Network option to add hosts to the HIT Group, verify that the network browser is working in
Windows.
NOTE:
If you cannot add hosts by browsing the network; add them manually by using the Manual Entry option in the Add
Hosts wizard.
