Configuring WMI Mapper proxy server settings for Hyper-V Virtual Machine Management Pack uses WMI Mapper proxy bundled with HP SIM to manage the Hyper-V virtualization layer. If the WMI Mapper proxy is installed on the server where HP SIM 5.3 is installed, no additional configuration is required in Virtual Machine Management Pack. If the WMI Mapper proxy is installed outside the CMS, add the following configuration entry in the VMM configuration file located at /bin/hpvmm.conf for Virtual Machine Management Pack to manage Hyper-V servers. WMIProxyServer = By default, the WMI Mapper proxy port used by VMM is 5989. If the WMI Mapper proxy service is run on a different port, add the following configuration entry in the VMM configuration file located at /bin/hpvmm.conf. WMIProxyPort = After any changes to the hpvmm.conf file, Virtual Machine Management Pack on the CMS must be restarted for the changes to take effect. Configuring the polling frequency for virtual machine status checks Virtual Machine Management Pack provides a configurable parameter called VMConfigRefreshRate. This parameter controls the frequency with which the VMM Agent checks for changes in virtual machine configuration, such as number of NICs on the virtual machine, size of the hard disk, and so on. Configuration changes on the virtual machines are updated by Virtual Machine Management Pack. The default polling frequency is 5 seconds. In the hpvmm.conf file, the polling frequency can be changed by updating VMConfigRefreshRate=> The configuration file can be found in the following locations: • For VMware ESX Server-/usr/share/vmm/bin/hpvmm.conf. • For Microsoft Virtual Servers and VMware Server 1.0.x- /bin/hpvmm.conf • For Hypervisors being managed in an agent-less fashion- /bin/hpvmm.conf If the hpvmm.conf file is not present, then a text file named hpvmm.conf must be created in the appropriate location listed above. The value of the parameter can be between 5 seconds and 5 minutes. Any values entered outside this range are automatically adjusted to the max/min value of the range. Because increasing the polling frequency also reduces the ability of Virtual Machine Management Pack to learn the changes in virtual machine status. HP recommends that you change this frequency if you simultaneously use the VMware Consolidated Backup (VCB) and Virtual Machine Management Pack. Handling prefailure events For Hyper-V and Xen on RHEL and SLES, prefailure events are not supported. HP SIM can detect certain prefailure alerts and generate corresponding events. Virtual Machine Management Pack uses VMotion for VMware and XenMotion for HP integrated Citrix XenServer as event handlers for these events, so that the virtual machine can be moved to an alternate host before the system fails or is placed in maintenance mode. The capability to detect prefailure alerts is supported in the following cases: • VirtualCenter 2.x platforms and for VMware ESX hosts and virtual machines that are on shared storage • HP integrated Citrix XenServer, XenServer host, and virtual machines that are on shared storage in a resource pool Handling automatic prefailure events 1.

Configuring WMI Mapper proxy server settings for Hyper-V
Virtual Machine Management Pack uses WMI Mapper proxy bundled with HP SIM to manage the Hyper-V
virtualization layer. If the WMI Mapper proxy is installed on the server where HP SIM 5.3 is installed, no
additional configuration is required in Virtual Machine Management Pack.
If the WMI Mapper proxy is installed outside the CMS, add the following configuration entry in the VMM
configuration file located at
<HP VMM installation directory on CMS>
/bin/hpvmm.conf
for
Virtual Machine Management Pack to manage Hyper-V servers.
WMIProxyServer =
<IP address of the server where WMI Mapper proxy is installed>
By default, the WMI Mapper proxy port used by VMM is
5989
. If the WMI Mapper proxy service is run on
a different port, add the following configuration entry in the VMM configuration file located at
<HP VMM
installation directory on CMS>
/bin/hpvmm.conf
.
WMIProxyPort =
<Proxy port number>
After any changes to the
hpvmm.conf
file, Virtual Machine Management Pack on the CMS must be restarted
for the changes to take effect.
Configuring the polling frequency for virtual machine status checks
Virtual Machine Management Pack provides a configurable parameter called VMConfigRefreshRate. This
parameter controls the frequency with which the VMM Agent checks for changes in virtual machine
configuration, such as number of NICs on the virtual machine, size of the hard disk, and so on. Configuration
changes on the virtual machines are updated by Virtual Machine Management Pack. The default polling
frequency is 5 seconds.
In the
hpvmm.conf
file, the polling frequency can be changed by updating
VMConfigRefreshRate=<< value in milli seconds >>
The configuration file can be found in the following locations:
•
For VMware ESX Server—
/usr/share/vmm/bin/hpvmm.conf
.
•
For Microsoft Virtual Servers and VMware Server 1.0.
x
—
<HP VMM Agent installation directory>
/bin/hpvmm.conf
•
For Hypervisors being managed in an agent-less fashion—
<HP VMM installation directory
on CMS>
/bin/hpvmm.conf
If the
hpvmm.conf
file is not present, then a text file named
hpvmm.conf
must be created in the appropriate
location listed above. The value of the parameter can be between 5 seconds and 5 minutes. Any values
entered outside this range are automatically adjusted to the max/min value of the range.
Because increasing the polling frequency also reduces the ability of Virtual Machine Management Pack to
learn the changes in virtual machine status. HP recommends that you change this frequency if you
simultaneously use the VMware Consolidated Backup (VCB) and Virtual Machine Management Pack.
Handling prefailure events
For Hyper-V and Xen on RHEL and SLES, prefailure events are not supported.
HP SIM can detect certain prefailure alerts and generate corresponding events. Virtual Machine Management
Pack uses VMotion for VMware and XenMotion for HP integrated Citrix XenServer as event handlers for
these events, so that the virtual machine can be moved to an alternate host before the system fails or is placed
in maintenance mode.
The capability to detect prefailure alerts is supported in the following cases:
•
VirtualCenter 2.
x
platforms and for VMware ESX hosts and virtual machines that are on shared storage
•
HP integrated Citrix XenServer, XenServer host, and virtual machines that are on shared storage in a
resource pool
