Bug ID 15736312
If one or more Sun Flash Accelerator F20 PCIe HBA (TA-FAS-S31E96GB-N) is added, and RHEL 5.x or Oracle Linux 5.x is installed without changing the boot order and GRUB boot loader, then RHEL/Oracle Enterprise Linux will not boot up successfully and the screen will show "No Active Partition."
Affected hardware and software:
Sun Fire X4170 M2 Server
Sun Fire X4270 M2 Server
Sun Flash Accelerator F20 PCIe HBA
Oracle Linux 5.x
Red Hat Enterprise Linux (RHEL) 5.x
Workaround:
Manually change the GRUB boot loader during the OS installation.
Make sure your OS is installed on the hard disk instead of on the FMODs in the flash F20 card.
Set the LSI SAS controller as the first boot in the BIOS boot device menu.
