HP Serviceguard for Linux Version A.11.19 Deployment Guide, September 2012

2. Import the volume groups by running the vgscan command.

vgscan

Reading all physical volumes. This may take a while...

Found volume group "vgclog" using metadata type lvm2

Found volume group "vgws" using metadata type lvm2

NOTE: If the volume groups, vgws and vgclog are not found, reboot the server.

3. Create the mount points

mkdir /ws

mkdir /clog

4. Backup the volume group configurations

vgcfgbackup /dev/vgws /dev/vgclog

5. Deactivate the volume groups on this server

vgchange –a n vgws vgclog

Network Configuration

Configure Network Bonding

In this step, you will configure a bonded network interface. You will need to determine which

interfaces are participating in the bond. In the following example, eth2 and eth3 are configured to

create the bond0 logical interface to meet the minimum requirements for Serviceguard for Linux.

These steps should be performed on each server, using the appropriate IP and MAC addresses.

In this example, we show the content of the 3 configuration files in the /etc/sysconfig/network-scripts

directory required to create the bonded interface. The ifcfg-eth# files may already exist, but the ifcfg-

bond0 file probably does not exist.

1. Change directory:

cd /etc/sysconfig/network-scripts

2. Create ifcfg-bond0 and add the IP address and other network addresses according to your

environment as well as the other fields listed here, for example:

DEVICE=bond0

IPADDR=16.89.84.247

NETMASK=255.255.255.128

NETWORK=16.89.84.128

BROADCAST=16.89.84.255

ONBOOT=yes

BOOTPROTO=none

USERCTL=no

BONDING_OPTS='miimon=100 mode=1'

NOTE: There is no space between the key-value pair variables. For example, there should not

be any space between DEVICE (key) and bond0 (value) pair.

3. Edit the ifcfg-ethN file to contain the following content. Remove existing entries, if any,

except for “DEVICE” and “HWADDR”. Make sure that the HWADDR field matches the

specific MAC address for the card, do not use the value listed here. Here is an example for

ifcfg-eth2:
