Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Create a new file under /etc/init.d/tty.conf with vi or any text editor you like."

A block of code is set as follows:

<fencedevices>
  <fencedevice agent="fence_ifmib" community="Mycluster_community" ipaddr="192.168.1.45" name="fence_ifmib_SW1" snmp_version="2c" />
  <fencedevice agent="fence_ifmib" community="Mycluster_community" ipaddr="192.168.1.46" name="fence_ifmib_SW2" snmp_version="2c" />
  </fencedevices>

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

</rm>
 <failoverdomains>
 <failoverdomain name="myfailover" nofailback="1" ordered="1" restricted="1">
 <failoverdomainnode name="vmsrv01" priority="1"/>
 <failoverdomainnode name="vmsrv02" priority="2"/>
 </failoverdomain>
 </failoverdomains>
<pvevm>

Any command-line input or output is written as follows:

sudo apt-get install lshw
