HP Integrity Virtual Server Manager 6.0 User Guide

connections to those virtual partitions are trusted; otherwise, some information is not displayed by
Virtual Server Manager. For example, if a certificate is missing, utilization meters are labeled No
Data. For more information about trusted certificates and how to store them in a keystore on the
VSP, see “Trusted certificates” (page 15).
You can use the basic features of the HP SMH version of Virtual Server Manager without exposing
user credentials or configuration data on the local network. In this case, you see a subset of the
potential information that the Virtual Server Manager can display. To have all data displayed, the
following steps are required.
NOTE: Displaying all the information about the virtual partitions' configuration exposes the
credentials of a connecting user.
1. Create a nonlogin, nonprivileged account on each virtual partition to which Virtual Server
Manager might connect and whose credentials can be intercepted on the network. Although
these credentials are restricted to nonlogin capabilities, they can also be used to gain access
to other data or actions available using WBEM and other nonlogin services, including those
from additional providers that are registered on the system.
2. Optional, for additional security: If local policy is to avoid exposure of any account credentials
on your network, or if you do not want to expose the virtual partition configuration data, then
configure an SSH or IPSec tunnel from the VSP system to each virtual partition for port 5989
(HP WBEM Services).
The following types of information require credentials for each virtual partition for which information
is to be gathered:
• Operating System: If the required credentials are not set for a virtual partition, Virtual Server
Manager cannot contact the machine. Virtual Server Manager displays the expected operating
system (if the operating system was set during configuration of the virtual partition, or if the
guest operating system on the virtual partition has been booted). If the credentials are set and
the virtual partition is running with the proper provider, Virtual Server Manager displays the
operating system and version number.
• Utilization: If the required credentials are not set for a virtual partition, the utilization meters
for virtual partition-specific items are dimmed. (Meters specific to a virtual partition are located
on such Virtual Server Manager pages as the VSP Virtual Partitions tab, the vPars Properties
Network and vPars Properties Storage tabs, and the vPars Properties General tab. For more
information about these tabs, see Chapter 4 (page 21).) Meters for the VSP and host resources
are still available if the VSP's WBEM Utilization Provider is running.
The data is a 5-minute average that is calculated and updated on 5-minute boundaries.
When a utilization meter is dimmed, a label next to the meter indicates the probable cause.
These labels and status indicators are described in “Utilization meter status/error information”
(page 127).
Virtual LAN interface I/O utilization on the vPars Properties Network tab: For a virtual partition
with invalid credentials, either the No Perm. or No Data label appears next to the meter.
The page still displays whatever information is available from the VSP, such as the status and
the bus, device, and function numbers for a virtual LAN interface. For a virtual partition with
valid credentials, Virtual Server Manager displays I/O utilization data for each virtual LAN
interface and for VM aggregated LAN interfaces.
Virtual storage device I/O utilization on the vPars Properties Storage tab: For a virtual partition
with invalid credentials, either the No Perm. or No Data label appears next to the meter.
The page still displays whatever information is available from the VSP, such as the virtual
device type and the bus, device, and target numbers for the virtual storage device. For a
