HP XP7 Command View Advanced Edition Administrator Guide (Web Version) (TK981-96004, May 2014)

• If the OS of the host is Windows, the Device Manager agent will not acquire data from devices
assigned the drive letter A or B. Assign a drive letter from C to Z for a device managed by the
Device Manager agent.
• If you change a device file name by using the rendev command on a host whose OS is AIX 7.1
or AIX 6.1 TL6 or later, the new device name must be specified by using printable ASCII characters
only. If a character other than a printable ASCII character is included in the name, the Device
Manager agent will not work properly.
• To execute Device Manager agent commands other than hdvm_info, you must be a member of
the Administrators group or a superuser.
• When using one of the following OSs on the host, execute Device Manager agent commands
from the WOW64 command prompt:
Windows Server 2008 (x64 and IPF)
Windows Server 2008 R2 (x64 and IPF)
Windows Server 2012 (x64)
Windows Server 2012 R2 (x64)
The following shows an example of executing from the command prompt:
C:\WINDOWS\SysWOW64\cmd.exe
• In Windows, the folder in which the Device Manager agent commands are installed is automatically
added to the environment variable PATH. When you execute a command, you do not need to
change the current folder to the folder that contains commands.
Specifying the Device Manager agent environment settings
Before you can start running the Device Manager agent, you must specify the necessary environment
settings.
Specify the following settings as necessary:
• Settings for changing the Java execution environment (Windows or Linux)
You must specify these settings if you change the Java execution environment used by the Device
Manager agent.
• Registering firewall exceptions (Windows)
You must specify these settings if you enable Windows Firewall after the Device Manager agent
has been installed or if you change the port used by the Device Manager agent.
• Registering a Java process in SED as an exception (AIX)
You must perform this registration if you change the SED mode to all after the Device Manager
agent has been installed.
• Settings for managing copy pairs
You must specify these settings if you use Device Manager or Replication Manager to manage
copy pairs.
• Settings required when 100 or more LUs are managed for a host
You must specify these settings if a host recognizes 100 or more LUs that are managed by Device
Manager.
• Settings for changing the user of the Device Manager agent service (Windows)
You must specify these settings to change the user of the Device Manager agent service to an
Administrators group member to enable operations on HORCM instances activated by the Device
Manager agent (default: LocalSystem).
