Page: 395 / 651

If this CEC I/O group is assigned to a logical partition that’s not running Linux, or not assigned
to any partition, setting the Linux compatibility mode is not required.
Note: In the list of devices under Group_128 on the HMC, port two on the integrated SCSI controller
(U0.1-P2/Z2) is not shown, but is included in Group_128.
Non-partitioned systems:
When the 7028 Model 6C4 system is not partitioned (also known as not running in LPAR
mode), the boot mode menu allows you to select a boot mode.

To select a boot mode, select a number and press Enter. The item corresponding to the selected
number toggles between Disabled to Enabled. If a boot mode is Enabled, the boot mode selected is
performed, and the Disabled/Enabled selection is reset to Disabled. The following describes each boot
mode:
– Boot to SMS Menu
When this selection is enabled, the system boots to the System Management Services (SMS) Menu.
– Service Mode Boot from Saved List
This selection causes the system to perform a service mode boot using the service mode boot list
saved in NVRAM. If the system boots AIX from the disk drive and AIX diagnostics are loaded on the
disk drive, AIX boots to the diagnostics menu.
Using this option to boot the system is the preferred way to run online diagnostics.
– Service Mode Boot from Default List
This selection is similar to Service Mode Boot from Saved List , except the system boots using the
default boot list that is stored in the system firmware. This is normally used to try to boot customer
diagnostics from the CD-ROM drive.
Using this option to boot the system is the preferred way to run standalone diagnostics.
– Boot to Open Firmware
This option should only be used by service personnel to obtain additional debug information. When
this selection is enabled, the system boots to the open firmware prompt.
