Changing A Logical Partition Load Source Resource - IBM AS/400e Manual

1. Go to the Display System I/O Resources display and verify that both logical partitions share the bus to
which the IOP is attached. One logical partition can own the bus with own bus shared status, and the
other use it with use bus shared status. Or both logical partitions can use the bus with use bus shared
status.
2. Remove the candidate IOP from the logical partition that owns it.
3. Add the candidate IOP to the target logical partition. You do not have to restart the system to activate
the change.
After you add the IOP to the logical partition, you might need to designate it as the partition alternate IPL
or electronic customer support IOP. Removing an IOP marked for special function clears all such
designation and leaves the partition without this special resource until you specify another.

Changing a logical partition load source resource

Attention: If you change a load source for a logical partition, the following could happen:
v You could lose all system data for the logical partition.
v You might have to reinstall the logical partition.
v You might have to reinstall the operating system on the logical partition.
If you need to reinsatll the operating system, refer to the AS/400e Software Installation
instructions.
A logical partition load source is an I/O processor (IOP) with at least one disk unit that contains the
|
Licensed Internal Code for the system. If your system is using mirroring, there may be two load source two
|
| disk units. The load source is one of the tagged resources. To be valid, all logical partitions must have a
load source resource.
|
| You can perform this procedure from dedicated service tools (DST) or system service tools (SST). Follow
these steps to change a load source resource:
|
1. Start SST or DST.
|
2. From SST select option 5 (Work with system partitions); from DST select option 11 (Work with System
|
| Partitions).
3. Selection option 3 (Work with partition configuration).
|
4. Use the cursor to select the logical partition you want to change.
|
5. Select option 6 (Select load source resource)
|
Note: The list of resources displayed contains load source capable IOPs with disk units in the proper
|
position. If the disk units in on this IOP are new, the IOP might be filtered out of the of the list in the
|
| Select Load Source Resource display. If you cannot see the IOP you want to tag, disable filtering
by pressing the F9 key.
|
6. Use the cursor to choose the IOP with the new load source resource disk units.
|
7. Select option 1 (Select IOP).
|
| 8. Press Enter.
| 9. At the confirmation display press enter to confirm your choice.
