While the firmware is running POST and before the operating system starts, a POST menu with POST indicators is displayed. The POST indicators are the words Memory, Keyboard, Network, SCSI, and Speaker that are displayed as each component is tested. You can then select configuration utilities from the POST menu.
Use the system management services (SMS) utility to view information about your system or partition and to perform tasks such as setting up remote IPL, changing self configuring SCSI device (SCSD) settings, and selecting boot options. The SMS utility can be used for AIX® or Linux partitions. See Using the SMS utility for more information.
Use this utility to initiate a system boot in service mode, using the customized service mode boot list that was set up by AIX when AIX was first booted, or manually using the AIX service aids.
This utility is for advanced users of the IEEE 1275 specifications only.
Use the management module to change the boot list, determine which firmware image to boot, and perform other configuration tasks.
