Abstract This white paper summarizes the installation and configuration of HP Insight Control for Linux (ICLinux) to manage, in conjunction with Oracle VM Manager, an Oracle VM environment deployed on HP ProLiant DL785 G6 servers. IC-Linux manages the physical server environment and Oracle VM Manager manages the virtualization environment. Oracle VM is server virtualization software that fully supports both Oracle and non-Oracle applications.

• HP StorageWorks Enterprise Virtual Array 4400 or HP StorageWorks MSA2000 The following sections describe these components. HP Insight Control for Linux (HP IC-Linux) management suite HP Insight Control for Linux (IC-Linux) is an integrated management solution for multi-system Linux environments of industry-standard HP ProLiant servers with productivity for administrators in both Enterprise and Cluster environments.

• Reliability features, such as redundant power supplies and fans, ASR, pre-failure warranty, ensure the HP ProLiant DL785 G6 is well suited to support an enterprise class environment For more information on the HP ProLiant DL785 G6 servers, see the following website: http://www.hp.com/servers/dl785 HP ProLiant Server For information on the HP ProLiant servers, see the following website: http://www.hp.

Figure 1. Configuration with Oracle VM and HP IC-Linux for HP ProLiant DL785 G6 The following are the main components of this configuration: • Central Management Server (CMS) The Central Management Server (CMS) is an HP ProLiant system that runs HP IC-Linux and Oracle VM Manager. HP IC-Linux performs Oracle VM Server deployment, firmware management, power management, host and guest performance monitoring, and other IC-Linux functions to manage the HP ProLiant Server.
PAGE 7
The Oracle VM Manager installs the virtual machines, controls them (for example, power on and off, pause, and delete), manages the Oracle VM Templates for use in installation, and provides high availability services for the virtual machines. Oracle VM Manager uses an agent on the managed host Oracle VM Server to enable the virtual guest functions it provides. The agent is included in the OVM Server installation; it is not deployed by OVM Manager.
PAGE 8
Installing IC-Linux on the CMS HP Insight Control for Linux v6.0 (IC-Linux v6.0) or higher must be used for this solution. HP IC-Linux is available for trial use or purchase from the following website: http://www.hp.com/go/ic-linux • HP IC-Linux v6.0 with 1-license for a single ProLiant system (464423-B22) • HP IC-Linux v6.0 licenses for multiple ProLiant systems (464425-B22) (Note: You need multiple licenses if you have multiple HP ProLiant DL 785 G6 managed nodes.

2. Unzip the downloaded ZIP file as follows: # unzip V18419-01.zip You can download the unzip software from the following location: http://public-yum.oracle.com/repo/EnterpriseLinux/EL5/3/base/i386/unzip-5.52-3.el5.i386.rpm 3. As root mount the ISO file extracted from the ZIP file (OracleVM-Manager-2.2.0.iso) as follows: # mount –o loop OracleVM-Manager-2.2.0.iso /mnt 4. Run the installation script as follows: # cd /mnt # ./runInstaller.

# unzip V18336-01.zip You can download the unzip software from the following location: http://public-yum.oracle.com/repo/EnterpriseLinux/EL5/3/base/i386/unzip-5.52-3.el5.i386.rpm 3. Create an Oracle VM Server repository from the HP SIM GUI by selecting Options→ICE- Linux→Manage Repository→New. 4. Select Custom OS and click Next. 5. Enter the Custom OS Configuration as follows: Important: The Custom OS Name can be ovm22. 6. Click Save.

9. Copy the boot files to the /opt/repository/boot/ovm22Boot directory as follows: # cp /mnt/images/pxeboot/initrd.img /mnt/images/pxeboot/vmlinz /opt/repository/boot/ovm22Boot 10. Unmount the ISO file as follows: # umount /mnt 11. Copy the sample Kickstart template file to the Custom OS IC-Linux repository. For example: # cp /opt/repository/contrib/ovs-tools/ovm-22-sample-iclx6.cfg \ /opt/repository/instconfig/custom/ovm22/install_conf 12.

4. For each Oracle VM Server host, select the host from the CMS, then select Configure→Configure and repair agents to enable SSH connections. 5. For each Oracle VM Server host, select the host from the CMS, then install the Nagios agents. Select Options→ICE-Linux→Configure Management Services. 6. Monitor the Oracle VM Server using Nagios. For more information on setting up IC-Linux management of the Oracle VM Server hosts, see the HP IC-Linux Version 6.0 User Guide.

Remove the default local repository from each server in the pool. For example, the following command returns the repository name and UUID on a server: # /opt/ovs-agent-2.3/utils/repos.py –-list Copy the UUID and use it to delete the local repository. For example: # /opt/ovs-agent-2.3/utils/repos.py –-delete UUID 5.

6. Verify that the virtual disks (for example, the 253 major numbered devices) are seen in each individual server as follows: # cat /proc/partitions 104 0 143338560 cciss/c0d0 104 1 142279641 cciss/c0d0p1 104 2 1052257 cciss/c0d0p2 8 0 209715200 sda 8 16 20971520 sdb 8 32 31457280 sdc 8 48 209715200 sdd 8 64 20971520 sde 8 80 31457280 sdf 253 0 209715200 dm-0 253 1 20971520 dm-1 253 2 31457280 dm-2 7.

Note: Create the repository only on the Oracle VM Server Pool Master. 11. Set the repository as the cluster root. For example, the following command returns a list of the storage repositories including the UUID for each one: # /opt/ovs-agent-2.3/utils/repos.py –-list Copy the UUID and use it to set the repository as the cluster root. For example: # /opt/ovs-agent-2.3/utils/repos.py –-r UUID Note: Do not mount the remote virtual disk locally on any server.

4. Log in to the CMS web interface. Select Tools→Integrated Consoles→OVM Manager to verify that the link works. No MAC addresses registered for system Problem: During the installation, deployment, or capture of IC-Linux, the Configure System to Boot from Network step fails with the following message: There are no MAC addresses registered for this system. Workaround: Bare metal boot the system as follows: 1. Determine the target system MAC address from DHCP. 2.
