IBM Link: Using SMS To Choose Boot Device

Question

Needing to boot from a specific disk, use SMS to select the boot device.

Answer

This is an example of booting into SMS mode on a pSeries machine in order to select a device to boot from.

To enter SMS mode, you can either press 1 when prompted by the system, or if the host is an LPAR attached to an HMC you can select the LPAR, pull down Operations -> Activate, then select Advanced -> Boot Mode -> SMS

To use 1 to get into SMS, press it when you see this screen:

          1 = SMS Menu                          5 = Default Boot List
          8 = Open Firmware Prompt              6 = Stored Boot List


     Memory      Keyboard     Network     SCSI     Speaker 

At that time SMS will start up from firmware:

 Select Device Type
 1.   Diskette
 2.   Tape
 3.   CD/DVD
 4.   IDE
 5.   Hard Drive
 6.   Network
 7.   List all Devices

At this point you can either choose a specific boot device or let the firmware probe for all bootable devices. If 7 is chosen it will report back on any bootable adapters, and list any disks that are found to have an AIX boot image on them.

 1.        -      Virtual Ethernet 
                  ( loc=U9133.55A.105C2EH-V10-C2-T1 )
 2.        1      SCSI 107374 MB FC Harddisk, part=2 (AIX 6.1.0)
                  ( loc=U787B.001.DNWG2AB-P1-C2-T1-W200400a0b833530d-L0 )
 3.        4      SCSI 107374 MB FC Harddisk, part=2 (AIX 6.1.0)

In this example I have chosen “List all Devices”, and after probing it finds 2 SAN-attached disks and one virtual Ethernet adapter. In this case hdisk0 is the disk in position 1 and hdisk1 is the disk in position 4.

Choosing device number 3 to boot from hdisk1, this menu will appear:

 1.   Information
 2.   Normal Mode Boot
 3.   Service Mode Boot

To boot the system into Normal Mode (multiuser) choose option 2, or choose option 3 to boot into Diagnostics Mode or exit Diagnostics to Single User Mode.
