Managing HP Serviceguard A.11.20.10 for Linux, December 2012

REMOTE_IPADDR=''
STARTMODE='onboot'
BONDING_MASTER='yes'
BONDING_MODULE_OPTS='miimon=100 mode=1'
BONDING_SLAVE0='eth0'
BONDING_SLAVE1='eth1'
The above example configures bond0 with mii monitor equal to 100 and active-backup mode.
Adjust the IP, BROADCAST, NETMASK, and NETWORK parameters to correspond to your
configuration.
As you can see, you are adding the configuration options BONDING_MASTER,
BONDING-MODULE_OPTS, and BONDING_SLAVE. BONDING-MODULE_OPTS are the additional
options you want to pass to the bonding module. You cannot pass max_bonds as an option, and
you do not need to because the ifup script will load the module for each bond needed.
BONDING_SLAVE tells ifup which Ethernet devices to enslave to bond0. So if you wanted to
bond four Ethernet devices you would add:
BONDING_SLAVE2='eth2'
BONDING_SLAVE3='eth3'
NOTE: Use ifconfig to find the relationship between eth IDs and the MAC addresses.
For more networking information on bonding, see
/usr/src/linux<kernel_version>/Documentation/networking/bonding.txt.
5.1.9.1 Restarting Networking
Restart the networking subsystem. From the console of any node in the cluster, execute the following
command on a SUSE system:
/etc/init.d/network restart
NOTE: It is better not to restart the network from outside the cluster subnet, as there is a chance
the network could go down before the command can complete.
If there is an error in any of the bonding configuration files, the network may not function properly.
If this occurs, check each configuration file for errors, then try to start the network again.
5.1.10 Setting up a Lock LUN
The lock LUN can be created on a partition of one cylinder of at least 100K defined (via the fdisk
command) as type Linux (83).
Alternatively, you can create the lock LUN on a whole LUN of at least 100K starting with the below
patches.
On Red Hat Enterprise Linux server, you have to install the following patches on Serviceguard Linux
Version A.11.20.00:
• SGLX_00339 for Red Hat Enterprise Linux 5 (x86_64 architecture)
• SGLX_00340 for Red Hat Enterprise Linux 6 (x86_64 architecture)
Patches can be downloaded from HP Support Center at http://www.hp.com/go/hpsc.
NOTE: On SUSE Linux Enterprise Server, the patches are not required as this feature is supported
on Serviceguard Linux Version A.11.20.10 main release.
You will need the pathnames for the lock LUN as it is seen on each cluster node. On one node,
use the fdisk command to define a partition of 1 cylinder, type 83, on this LUN. Here is an
example:
