HP Matrix Operating Environment 7.1 Release Notes

VM kernel port name used for management traffic must be “Management Network”
In VMware ESXi, the default name of the Virtual Machine (VM) kernel port used for management
traffic is “Management Network”. Do not modify this name in the vCenter client user interface. If
this name is modified, the following will result.
• When trying to activate a logical server, the ESXi hosts appear as Rejected Target hosts with
an error that the hosts are not part of vCenter, or that virtual machine management is unable
to get vCenter information for the VM host.
• The association between the host and vCenter does not appear in Systems Insight Manager.
Suggested action
Modify the Network Label of the VMKernel port used for management traffic to “Management
Network” by performing the following steps.
1. Log into the vCenter using the vCenter client.
2. Select the Hosts and Clusters view from the menu View→Inventory.
3. Select the ESXi server from the tree displayed in the left pane.
4. Select the Configuration tab from the right pane.
5. From the Hardware section, select Networking.
6. Click Properties for the Virtual Switch where the VMKernel port used for management traffic
is located. If there are multiple VMKernel ports located on multiple virtual switches and
configured for management traffic, select the switch that has the VMKernel port that has the
IP that is registered with HP Insight Control virtual machine management , or that will be used
for registration with virtual machine management.
7. In the pop-up that displays the virtual switch properties, select the service console port and
click the Edit button.
8. Change the Network Label to Management Network and click OK. Close the virtual switch
properties pop-up window.
It can take a maximum of five minutes for the cache to be refreshed and the API to report the ESXi
host.
Managing a Microsoft Hyper-V (or any MSCS) cluster when an alias is assigned by
DHCP
In Windows Server 2008 Failover Clusters, if the cluster alias is assigned using DHCP, the cluster
alias PTR (reverse lookup) record in DNS will be incorrect, and will cause the cluster to be incorrectly
discovered in Systems Insight Manager.
To correct this problem, delete the cluster objects from Systems Insight Manager, take the steps in
the Microsoft Knowledge Base article at http://support.microsoft.com/kb/969049 to modify the
cluster DNS behavior, and then rediscover the cluster in Systems Insight Manager.
User experience and application performance
Matrix OE is based on web client server technologies. Your perception of performance can be
affected by many external sources, including the central management server’s health, network
congestion and latency, and client side equipment and browser.
Every effort to balance performance and functionality has been made to the default settings to
create the best user experience under multiple browsers with different server environments. Changing
these default settings can result in adverse application responsiveness, which is more noticeable
in some browsers; for example, there are known memory issues in Internet Explorer 7 and 8 that
can be exposed in large scale environments. No matter which browser you choose to use, HP
recommends using the latest release and updates to improve your user experience and protect
your environment from the latest security threats.
