During the Linux installation, HP recommends taking the following actions that will affect the LifeKeeper for Linux environment. These items appear in the same
sequence as in the GnoRPM installation process; however, those actions not affecting LifeKeeper for Linux (for instance, keyboard configuration) are omitted.

•
Install Type—Select Custom so that you can specify disk partitions suited for LifeKeeper for Linux. At the Partitions screen, be sure to create the following partitions in addition to any others you create:
— /boot—at least 16 MB, type= Linux native
— swap—current Red Hat restriction is a maximum of 2 GB, but this should be 2X memory size, if possible.
— / (root directory)—this should be equal to remaining disk space. If Linux detects enough space, it automatically creates the necessary additional directories.
Choose Partitions to Format—Select Check for bad blocks while formatting to eliminate the risk of data loss due to bad blocks in the future. This can be a time-consuming task, depending on the size and number of disks that you have.
LILO Configuration—When installing LILO (the Linux Loader), be sure to select Linear mode (or add linear to /etc/lilo.conf), which is recommended when using SCSI disk drives.
Network Configuration—If the network information is not available, you can enter the host name now, and then enter the additional network information later.
NOTE: If you need to change the host name, you should do so before installing
LifeKeeper for Linux if at all possible. If you need to change the host name after installing LifeKeeper for Linux, refer to “Verifying the Network Configuration” section in previous chapters.

Package Group Selection—If you choose to select individual packages, be sure to include the following packages:
— Mail/WWW/Newstools—May be necessary if you plan to use Sendmail.
— Web Server—Select this if you intend to use the Apache (or some other) Web Server
— Development—Is needed in the event that you must rebuild the kernel.
— Kernel development—Is needed in the event that you must rebuild the kernel.
— Extra documentation—Is helpful for rebuilding the kernel
X Configuration—You should configure the X Server to provide support for the LifeKeeper GUI application. If necessary, customize the video card settings to obtain proper video resolution.
When running the LifeKeeper GUI application from a telnet session, you need to be sure that the GUI client is allowed to access the X Window Server on the LifeKeeper for Linux server. The LifeKeeper for Linux server must also be able to resolve the host name or network address of the GUI client. When you telnet into the LifeKeeper for Linux server to run the LifeKeeper GUI application, the DISPLAY environment variable should contain the client host name and display number. For example, if you telnet into a server named Server1 from a client named Client1, the DISPLAY environment variable should be set to Client1:0.
When you run the LifeKeeper GUI application, it will try to send the output to the DISPLAY name for Client1. If Client1 is not allowed access to the X Window Server, the LifeKeeper GUI application will fail with an exception.
Red Hat Development/Tools/patch 2.5-10—LifeKeeper for Linux requires that each server in the cluster have this patch installed. The patch is included on Red Hat installation media.
Installing Latest Ethernet Driver—If you are using a 3-Com Ethernet card, it is recommended that you install the latest Ethernet driver available at
www.redhat.com/support.

Operating System Installation Tips

Installing the pdksh Package—LifeKeeper for Linux has a dependency on the public domain korn shell (pdksh) package. You can install this package using GnoRPM. This is installed by default with Red Hat Linux Professional.
a. Insert the Linux CD in the CD-ROM drive. The GnoRPM window is displayed if you have autorun for the CD-ROM turned on. If autorun is not turned on, start it manually or use the command line options.
b. Click Install. The package manager detects the Linux CD and opens the Install window.
c. Click Add. The Add Packages window opens, displaying the Linux rpm packages.
d. Select System Environment, then select Shells.
e. Scroll to and select the pdksh package, then click Add.
f. Close the Add Packages window.
g. Click Install at the bottom of the Install window to begin the installation.
File System Labels—The use of file system labels in /etc/fstab will slow down fsck since it has to scan all partitions to determine what device a label refers to.
The mapping of labels to partitions is not stored in the OS so every time an fsck is done it must open every partition. This impacts LifeKeeper due to the fact that LifeKeeper has reserved the partitions that it has inservice. Every time fsck is performed from another server in the cluster, it will try to open the reserved partitions, and this will cause the OS/driver to perform error handling. The current workaround for this problem is to not use labels. Red Hat provides the option of using labels for the root file system. Users should not select this feature (or the monitor fstab feature) to be sure that the OS does not configure labels.
