4 HIT Groups Using a HIT Group, you can manage multiple hosts from any machine running ASM/ME. Topics: • Overview of HIT Groups • Create a HIT Group - Overview • Edit ASM/ME Settings on Hosts in a HIT Group Overview of HIT Groups A HIT Group contains one or more hosts that you manage from ASM/ME. For example, if an administrator needs to back up and create a Smart Copy for multiple machines, the administrator can perform all ASM/ME Smart Copy operations from a single instance of ASM/ME. Similarly, if the administrator has to manage and backup Exchange mailbox databases residing on multiple servers, the administrator can create a HIT Group on a single instance of ASM/ME, and then manage multiple servers from that instance. HIT Groups allow you to create and manage Smart Copies and Smart Copy schedules on all your hosts, and simultaneously edit settings on multiple hosts. When you add a new host to a HIT Group, HIT/Microsoft is installed on the host. For a previously-created HIT Group, ASM/ME informs you when any of the hosts are not running a version of HIT/Microsoft equal to the version on the local host. You can then use the Add Hosts wizard to remotely update HIT/Microsoft on the other hosts. ASM/ME Operations on HIT Group Members Assume you have created a HIT Group that includes your local host, and three hosts that you have added to it for managing with ASM/ME. You can perform any ASM/ME operation on the local host and any of the three hosts that you have added. Select the appropriate host from the tree panel, and then perform the ASM/ME operation from that view. Perform ASM/ME operations on the remote hosts exactly as you would perform operations on the local host. HIT Groups in Non-Cluster Environments In non-cluster environments, HIT Groups are host-specific. That is, adding Host B to the ASM/ME instance on Host A does not automatically add Host A to the ASM/ME instance on Host B. A HIT Group can consist of one host. Adding multiple hosts to manage is optional; you can run ASM/ME from a single host and manage that local host. Assume that you have three hosts: A, B, and C and that each host is running an instance of ASM/ME. From the ASM/ME instance on Host A, you can add hosts B and C. This feature enables you to perform all ASM/ME operations on hosts B and C from the ASM/ME console on Host A. However, if you then view the instances of ASM/ME running on hosts B or C, you are not able to see Host A or perform ASM/ME operations on Host A until you add Host A from that specific host. The following figure illustrates a two-member HIT Group in a standard non-cluster environment. In this example, Host A can add Host B for management so it can manage itself as well as Host B.

HIT Groups
Using a HIT Group, you can manage multiple hosts from any machine running ASM/ME.

Overview of HIT Groups
A HIT Group contains one or more hosts that you manage from ASM/ME. For example, if an administrator needs to back up and create a
Smart Copy for multiple machines, the administrator can perform all ASM/ME Smart Copy operations from a single instance of ASM/ME.
Similarly, if the administrator has to manage and backup Exchange mailbox databases residing on multiple servers, the administrator can
create a HIT Group on a single instance of ASM/ME, and then manage multiple servers from that instance.
HIT Groups allow you to create and manage Smart Copies and Smart Copy schedules on all your hosts, and simultaneously edit settings on
multiple hosts. When you add a new host to a HIT Group, HIT/Microsoft is installed on the host. For a previously-created HIT Group,
ASM/ME informs you when any of the hosts are not running a version of HIT/Microsoft equal to the version on the local host. You can
then use the
Add Hosts
wizard to remotely update HIT/Microsoft on the other hosts.
ASM/ME Operations on HIT Group Members
Assume you have created a HIT Group that includes your local host, and three hosts that you have added to it for managing with
ASM/ME. You can perform any ASM/ME operation on the local host and any of the three hosts that you have added. Select the
appropriate host from the tree panel, and then perform the ASM/ME operation from that view. Perform ASM/ME operations on the
remote hosts exactly as you would perform operations on the local host.
HIT Groups in Non-Cluster Environments
In non-cluster environments, HIT Groups are host-specific. That is, adding Host B to the ASM/ME instance on Host A does not
automatically add Host A to the ASM/ME instance on Host B. A HIT Group can consist of one host. Adding multiple hosts to manage is
optional; you can run ASM/ME from a single host and manage that local host.
Assume that you have three hosts: A, B, and C and that each host is running an instance of ASM/ME. From the ASM/ME instance on
Host A, you can add hosts B and C. This feature enables you to perform all ASM/ME operations on hosts B and C from the ASM/ME
console on Host A. However, if you then view the instances of ASM/ME running on hosts B or C, you are not able to see Host A or
perform ASM/ME operations on Host A until you add Host A from that specific host.
The following figure illustrates a two-member HIT Group in a standard non-cluster environment. In this example, Host A can add Host B
for management so it can manage itself as well as Host B.
