1. Shut down the nodes and disconnect them from their power source.
2. When using power switches, set up the switches and connect each node to a power
switch. Refer to Section 2.5.2 Configuring a Fence Device for more information.
In addition, it is recommended to connect each power switch (or each node's power
cord if not using power switches) to a different UPS system. Refer to Section 2.5.3
Configuring UPS Systems for information about using optional UPS systems.
3. Set up shared disk storage according to the vendor instructions and connect the nodes
to the external storage enclosure. Refer to Section 2.3.2 Shared Storage considera-
tions.
In addition, it is recommended to connect the storage enclosure to redundant UPS
systems. Refer to Section 2.5.3 Configuring UPS Systems for more information about
using optional UPS systems.
4. Turn on power to the hardware, and boot each cluster node. During the boot-up
process, enter the BIOS utility to modify the node setup, as follows:
Ensure that the SCSI identification number used by the host bus adapter is unique
•
for the SCSI bus it is attached to. Refer to Section A.3.4 SCSI Identification Num-
bers for more information about performing this task.
Enable or disable the onboard termination for each host bus adapter, as required by
•
the storage configuration. Refer to Section A.3.2 SCSI Bus Termination for more
information about performing this task.
Enable the node to automatically boot when it is powered on.
•
5. Exit from the BIOS utility, and continue to boot each node. Examine the startup
messages to verify that the Red Hat Enterprise Linux kernel has been configured and
can recognize the full set of shared disks. Use the
startup messages. Refer to Section 2.4.3 Displaying Console Startup Messages for
more information about using the
6. Set up the bonded Ethernet channels, if applicable. Refer to Section 2.5.1 Configur-
