Enabled host concepts
Enabled and standard hosts
Enabled and standard hosts
An enabled host is a computer in a SAN that is capable of performing I/O with connected storage
arrays and that has been configured to interact with the replication manager server. Only enabled
hosts are displayed in the replication manager interface.
A standard host is a computer in a SAN that is capable of performing I/O with connected storage
arrays, but has not been configured to interact with the replication manager server. Standard hosts
are not displayed in the replication manager interface.
Notes:
•
In HP P6000 Replication Solutions Manager documentation, the term “enabled host” refers
specifically to a host that has been configured with an HP P6000 Replication Solutions Manager
host agent.
•
A host can also be enabled with an HP Business Copy EVA/MA/EMA V2.x host agent. Such
host agents are part of HP Business Copy 2.x software and do not interact with or appear in
the replication manager interface. A host that is enabled with both host agents appears in
both interfaces.
Enabled host capabilities
When hosts are enabled, you can interact with them using the replication manager GUI, jobs, and
CLUI. For example, you can instruct an enabled host to dynamically mount a storage volume, or
suspend and resume application I/O when backing up virtual disks.
In addition, the replication manager can discover and interact with host volumes, volume groups,
and logical volumes.
Host names and ports
HP recommends that you use the same host name in HP P6000 Command View and the replication
manager to identify each host. This provides consistency in both interfaces when presenting a
virtual disk to a host.
An enabled host's storage system communication ports that are shared with HP P6000 Command
View are listed in the Enabled Hosts properties window, P6000 EVA Hosts tab. See
Viewing
enabled host properties.
Low-level refresh of enabled hosts
Update replication manager database entries by manually performing a discovery and refresh of
individual enabled hosts.
The action does the following:
•
Performs a discovery refresh of the enabled hosts to gather the host's properties
•
Updates the replication manager database with the new properties
Low-level refresh of VM servers
Update replication manager database entries by manually performing a discovery and refresh of
individual VM servers.
The action does the following:
•
Performs a discovery refresh of the VM servers to gather the server's properties
•
Updates the replication manager database with the new properties
