partition displays the SMS menus, all of the necessary tests have been performed and the machine is scanning the bus for a boot source.

Most system backplanes are designed such that the drive in the first slot spins up immediately after power-on, and other drives will wait for the operating system to send a command before spinning up. Disk drive bays 1 and 4 are hard-wired to spin up immediately. The left-most slot of the 3-pack disk backplanes (SCSI ID 5, boot, autostart) is set to spin up immediately after power-on. The power-on delay sequence is performed to prevent power supply overloading. This behavior makes the disk in the first slot of the first 3-pack DASD backplane the preferred boot device. See Figure 2-18to locate all of the disk bays.

When SMS menus are available, the Select Boot Options menu can be used to view and set various options regarding the installation devices and boot devices:

1.Select Install or Boot a Device

Enables you to select a device to boot from or install the operating system from. This selection is only for the current boot.

2.Select Boot Devices

Enables you to set the boot list.

3.Multiboot Startup

Toggles the multiboot startup flag, which controls whether the multiboot menu is invoked automatically on startup.

2.11.9Additional boot options

Instead of booting from the preferred boot device or from any other internal disks, there are a number of other possibilities:

DVD-ROM, DVD-RAM

These devices can be used to boot the system or a

 

logical partition (if the resource is available to the specific

 

partition), so that a system can be loaded, or system

 

maintenance or stand-alone diagnostics can be

 

performed.

External tape drives

Any externally attached tape drive can be used to boot

 

the system, or a logical partition if the resource is
