Operating System Installation Change
The Stratus Automated Uptime Layer for Linux-based ftServer Systems: Installation and Configuration (R013L) manual outlines the operating system install process in two chapters of the manual: one describing installation on internal disk; the second describing installation on external disks. In each chapter, there is a section title beginning "Installing the Operating System...", which summarizes a list of panels asking configuration questions during the installation. These relate to: Keyboard choice, Root Password, Create User, Date and Time settings, and Kdump configuration.
RHEL 6.2 adds a new panel following the Kdump configuration:
"Changing the Kdump settings requires rebooting the system to reallocate memory accordingly. Would you like to continue with the change and reboot the system after firstboot is complete?"
Answer "No" to this question. The system will be rebooted at a later point in the installation process, accepting the default values shown for Kdump configuration.

CPU BIOS Settings
The Stratus ftServer Systems: Technical Reference Guide (R550) provides technical information for ftServer 2600, 4500, 6300, and 6310 systems. In the chapter titled "ftServer BIOS Setup Tool", the section on "ftServer Setup Menus >> Advanced Menu" describes an option:
that enables or disables I/O Acceleration Technology. This option is disabled by default.
The I/O Acceleration Technology must always be disabled when running the Automated Uptime Layer. This BIOS option is not fully supported by the ftServer fault tolerant hardware, or by the Automated Uptime Layer software.
Grub Kernel Options
Stratus Automated Uptime Layer software running with the Red Hat Enterprise Linux operating system does not support use of the Linux Active State Power Management (ASPM) facility. The
Red Hat Enterprise Linux 6.2 introduced a problem in booting from internal disks, which use an MD RAID1 array for the root file system. If one array member disk is unavailable during the bootload, the root MD array does not get started and the bootload attempt fails. This problem is avoided by adding the following boot option to the kernel commands in
Stratus-provided scripts add these boot options whenever ftSSS software is installed or upgraded, when a new kernel RPM is installed, and each time the system is booted.
