Designing High Availability Solutions with HP Serviceguard and HP Integrity Virtual Machines

Where:

VM1 and VM1-2—the hostnames that will be associated with the IP addresses for the VM guest when it is running

in data center B

ht=ether—required setting

ha—set to the hardware address of the virtual network interfaces used by the guest

ip—set to the IP address to be assigned to the virtual network interface

ns—set to the subnet mask for the networks in data center B

ds—set to the IP address of the DNS server for data center B (optional)

4. Now you must enable the bootpd daemon. On the nodes in steps 2 and 3, edit the /etc/inetd.conf file and

uncomment the following line:

#bootps dgram udp wait root /usr/lbin/bootpd bootpd

Then reconfigure the Internet daemon, inetd, to re-read the configuration file:

# inetd –c

5. Now you can install your VM guest operating system, and during the installation process you will specify that the

network interfaces in the guest will use DHCP. If you have already installed and configured the VM guest to use

static IP addresses, you can use HP SMH or edit the /etc/rc.config.d/netconf file on the guest to change the

network configuration to use DHCP. You will need to reboot the VM guest operating system in order for the VM

guest to begin using DHCP to set the IP addresses for its virtual network interfaces.

Notes:

• Online migration of VM guests using DHCP is not supported between VM

hosts in different data centers in a cross-subnet configuration, as the live VM

guest will not update its IP addresses after an online migration.

• This example uses bootpd as the DHCP server, as the bootpd server is

simpler to configure than dhcpd. However, dhcpd also works equally well

as the DHCP server.

Integrity VM operating system and application support

The following is a summary of the operating systems and applications that are supported with Integrity VM:

• VM guest operating systems

– Refer to the Integrity VM documentation (

www.hp.com/go/hpux-hpvm-docs) for details of supported guest

operating systems

• Oracle

– Single–instance Oracle 9iR2, 10gR1/R2 in VM guests running HP-UX 11i v2 with Integrity VM B.03.50

and later

– Single–instance Oracle 11gR1/R2 in VM guests running HP-UX 11i v3 with Integrity VM B.04.20 or later

– For Oracle, the latest information can be found on Oracle’s MetaLink website

(

support.oracle.com/ Note: access to this site requires a support contract).

– RAC configurations are not supported at this time
