Managing HP Serviceguard A.11.20.10 for Linux, December 2012

For more information, see the white paper Using Serviceguard for Linux with VMware Virtual
Machines at http://www.hp.com/go/linux-serviceguard-docs.
4.3 Hardware Planning
Hardware planning requires examining the physical hardware itself. One useful procedure is to
sketch the hardware configuration in a diagram that shows adapter cards and buses, cabling,
disks and peripherals.
You may also find it useful to record the information on the Hardware worksheet (page 273) indicating
which device adapters occupy which slots and updating the details as you create the cluster
configuration. Use one form for each node (server).
4.3.1 SPU Information
SPU information includes the basic characteristics of the server systems you are using in the cluster.
You may want to record the following on the Hardware worksheet (page 273) :
Server Series Number Enter the series number, for example, DL980 G7.
Host Name Enter the name to be used on the system as the host name.
Memory Capacity Enter the memory in MB.
Number of I/O slots Indicate the number of slots.
4.3.2 LAN Information
While a minimum of one LAN interface per subnet is required, at least two LAN interfaces are
needed to eliminate single points of network failure.
HP recommends that you configure heartbeats on all subnets, including those to be used for client
data.
Collect the following information for each LAN interface:
Subnet Name The IP address for the subnet. Note that heartbeat IP addresses must
be on the same subnet on each node.
Interface Name The name of the LAN card as used by this node to access the subnet.
This name is shown by ifconfig after you install the card.
IP Address The IP address to be used on this interface.
An IPv4 address is a string of 4 digits separated with decimals, in
this form:
nnn.nnn.nnn.nnn
An IPV6 address is a string of 8 hexadecimal values separated with
colons, in this form:
xxx:xxx:xxx:xxx:xxx:xxx:xxx:xxx
For more details of IPv6 address format, see Appendix D (page 277).
Kind of LAN Traffic The purpose of the subnet. Valid types include the following:
• Heartbeat
• Client Traffic
Label the list to show the subnets that belong to a bridged net.
This information is used in creating the subnet groupings and identifying the IP addresses used in
the cluster and package configuration files.
