11 Using and maintaining the Device
Manager agent
This chapter provides notes on managing host operations and explains Device Manager agent settings
and operations.
Before using the Device Manager agent
This section provides notes on Device Manager agent operations and the settings required before
using Device Manager agent.
When to restart the Device Manager agent service
The Device Manager agent service needs to be restarted in the following cases:
• When the IP address of a host in which the Device Manager agent is installed is changed
• When the HBA driver or HBA API library is installed on a host in which the Device Manager agent
is installed
• When the contents of the property files of the Device Manager agent are modified
• When a new installation of P9000 Command View AE Suite is performed after the OS is re-installed
on the management server
• When RAID Manager is installed or uninstalled
• When Hitachi Dynamic Link Manager is installed or uninstalled on AIX or Linux
• When the execution of the hdvmagt_setting command is interrupted
If the Device Manager server service is not running, information is not reported to the server even if
a Device Manager agent is installed or a Device Manager agent service starts. For information to be
reported to the Device Manager server, verify that the Device Manager server service is running, and
then install a Device Manager agent or start the Device Manager agent service.
Specifying the IP address of the Device Manager agent network adapter
When the Device Manager agent runs on a host that has multiple network adapters, specify the IP
address of the network adapter used by the Device Manager agent in the
server.http.socket.agentAddress property in the server.properties file.
Applying storage system configuration changes to Device Manager server
The OS might not recognize the modified contents immediately after the storage system configuration
is changed (for example, when an LU is registered or deleted). In this case, the Device Manager agent
reports the old information to the Device Manager server. If the changes to the storage system
configuration have not been applied to the Device Manager server, perform the following procedure:
1. Execute the hldutil command to check the latest information.
