Assigning GUIDs for command devices on a Windows host agent
To overcome device renaming and device remapping issues during data collection, HP recommends
that you use the Windows GUID (\\?\Volume{GUID}) to perform configuration and performance
data collection instead of using the device file names.
Complete the following steps to use the GUID:
1. Log on to the HP XP P9000 Performance Advisor host agent and stop the host agent and
real-time services. For steps to stop these services, see “Starting, stopping, and restarting host
agent services” (page 124).
2. From a command line, run the XPInfo –i, to display the list of all the command devices
(see “XPInfo –i command” (page 83)).

member of the Administrators group.
