switch). Or, you can configure HP Integrated Lights-Out (iLO) to handle fencing. Refer to the

This chapter describes how to install GFS in the VTS environment. While you can follow the
instructions provided by
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.2/
html/Cluster_Administration/index.html to configure and manage GFS, this chapter provides
only the steps needed. (http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.2/
html/Global_File_System/index.html describes GFS and how to install a broader range of
tools.) Also, the steps in this chapter assume that the physical cabling of the servers and
storage is complete and connectivity has been verified.
To install GFS
1. Log in to the operating system of the VTS server as root.
2. Mount the GFS Install/Upgrade DVD. This example illustrates mounting the DVD on
/media/cdrom:
mkdir -p /media/cdrom
mount /dev/cdrom /media/cdrom
3. Install the GFS RPMs by entering the following command:
/media/cdrom/vts-6.04-gfs-install/installGFS.bash
Ignore any warnings that may be displayed.
4. Unmount and eject the DVD:
umount /media/cdrom
eject
5. Enter the following commands to disable clustering services that are included with the
GFS but not used by VTS. Failure to disable these can cause the system to hang.
chkconfig openais off && service openais stop
chkconfig saslauthd off && service saslauthd stop
If any of these commands returns a failure, it is not an error. It indicates that the process
was not running.
6. GFS RPMs inadvertently remove SCSI target mode support. To address this and
maintain correctly functioning virtual tape drives (VTDs), run the following command:
/usr/local/tape/bin/mkinitrd.pl -f
The VTS server is rebooted after this completes.
7. Repeat steps 1-6 on each server (node) that will be included in the cluster.
