Setting up an alternate installation device

Before you use an alternate installation device, certain requirements must be met.

You must enable the device. You need to record and keep the logical address of the system bus and system card at which the alternate installation device is attached. If you have the device set up on different bus and you do not have this information available, you will not be able to complete installations or recoveries.

If you change the configuration of your system, you need to ensure that this information is correct before you start to use the alternate installation device.

Do the following to set the addresses and enable the alternate installation device:
Note:
  • You need to know the password for Dedicated Service Tools to perform this procedure.
  • Logical partition users:
    • If you have a primary partition and are going to use the following command on the primary partition, be sure to power off all secondary partitions before running the command.
    • If you are using the Hardware Management Console, refer to the Managing your server using the Hardware Management Console topic .
  1. Use the control panel to set the mode to Manual. Then perform an IPL using the command: PWRDWNSYS OPTION(*IMMED) RESTART(*YES) IPLSRC(B)
    Note: An alternative to this step is to use the control panel to select function 21 (Dedicated Service Tools). If you use this alternative, go to step 3. You will not need to perform step 12.
  2. When the IPL or Install the System display appears, select option 3 (Use Dedicated Service Tools (DST)) and press the Enter key.
  3. The Dedicated Service Tools (DST) Sign On display appears.

    • Type/Model: _________
    • System bus: _________
    • System card: _________
    Note:
    1. You might want to repeat this process to record the addresses for all alternate installation devices that appear in step 6. You should store this information in a safe place, such as the location where your recovery information and recovery media are stored.
    2. If more than one alternate installation device is defined, only one can be enabled.
