HP StorageWorks P9000 Performance Advisor Software v5.4 Install Guide (T1789-96330, April 2012)

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 P9000 Performance Advisor host agent and stop the host agent and real-time ser-
vices. For steps to stop these services, see Appendix B.
2. From a command line, run the XPInfo –i, to display the list of all the command devices (see
Figure 14 on page 86).

3. Create a GUID on the command devices to perform data collection.
Complete the following steps:
a. Log on to the P9000 Performance Advisor host agent as an administrator or as a member
of the Administrators group.
b. Open the Computer Management console by clicking Start > Run > compmgmt.msc, and
press the Enter key.
c. Under Storage in the left pane, select Disk Management.
d. In the right pane, select a command device from the list of command devices displayed by
the P9000Info command (see Figure 14 on page 86).
