This checklist shows the sequence of tasks
to upgrade your load source disk unit (unit 1) with a disk unit that
has at least a 70-GB capacity. The disk units that are replaced in
this procedure are discarded.
Print a copy of this checklist. Check off the configuration
tasks as you perform them. This checklist provides an important record
of your actions. It may help you diagnose any problems that occur.
Before you begin
Evaluate your disk configuration and record your answers.
The information entered in the Before you begin table is needed to answer the questions in the Load
source planning section.

Task |
What to do |
1.___ |
Back up your system using the GO SAVE command. |
2.___ |

command prepares the partition to end. Use the immediate (*IMMED) value to end all active jobs
immediately and use the RESTART (*NO) value to power off the partition so that you can install disk
units in the next task. |
3.___ |
Install the replacement disk unit or assign a virtual storage LUN.
- If you are not using a virtual storage LUN for the replacement unit, ensure that there is an
open disk slot.
- Install the replacement disk unit on your system.
Notes:
- Ensure that the disk unit being installed has at least a 70-GB capacity and has
the same or greater capacity than the existing load source disk unit.
- It is recommended that you mark this disk unit with tape to remember its location. Mark this
disk unit differently than how you marked the existing load source disk unit.
|
4.___ |
Work with Dedicated Service Tools (DST).
- Power on your system or logical partition to Dedicated Service Tools (DST).
Note: Verify that you
are in manual mode before you power on your partition.

disk unit recovery.
- On the Work with Disk Unit Recovery display, select Copy
disk unit data.
- Type 1 next to load source disk unit (unit 1) and press Enter.
- Type 1 next to the disk unit that you installed in task 3.
- Write down the serial number of the replacement disk unit that
is going replace the load source.
|_________|
- Press Enter in the Confirm Copy Disk Unit Data display.
- The status display shows how the operation is proceeding. When the function is complete, the

- On the Use Dedicated Service Tools (DST) menu, select Start a service
tool.
- On the Start a Service Tool display, select Operator panel
functions.
- Use function F10 to power off the partition and press Enter.
Note: There is no command line because you are using Dedicated Service Tools.
|
7.__ |
Physically remove the disk unit.
- Physically remove the original load source disk unit (unit 1) that you identified in the Disk
configuration questions.
|
8.__ |
If the system has a Hardware Management Console (HMC) and the
disk unit that you installed in task 3 is under a different IOA than the original load source disk
unit, use the HMC to change the I/O tag.
- In your HMC, expand .
- Select the system.
- Select the check box for the partition.
- From the menu for the partition, click .
