A.2 Recognition procedure when an agent environment is changed
A unique ID used to identify a device (host identifier) is generated for a computer on which an agent is installed.
If you change the computer environment, whether a host identifier is generated depends on how the changes are made. When a host identifier is regenerated, the device is recognized as a different device from the device recognized before the environment was changed.
A host identifier is regenerated in the following cases:
-
The OS is reinstalled.
-
The hard disk drive on which the OS is installed was changed.
-
The motherboard is changed.#
-
The agent is installed on another computer from a disk copy.#
-
The resetnid.vbs command is executed.
-
The host ID management file becomes invalid, and the file is recreated.
#: If the host identifier has already been regenerated, the device is recognized as the same device as the device recognized before the environment was changed.
In all other cases, the host identifier is not regenerated. For example, the host identifier is not regenerated for the following cases:
-
The agent is uninstalled.
-
The agent is reinstalled after being uninstalled.
-
An overwrite installation of the agent is performed.
-
The CPU, memory, or a network card is replaced.
-
The OS is upgraded.
-
The hard disk drive size is increased.
- Tip
-
If a device is recognized as a different device, device information and hardware resource information before the change to the environment remain on the management server. If necessary, delete this information.
