Selecting or changing default electronic customer support resource
|
for logical partitions
|
| The default electronic customer support (ECS) resource is a tagged resource. It is the I/O processor (IOP)
with the modem necessary to receive electronic customer support.
|
| You can perform this procedure for system service tools (SST) or dedicated service tools (DST). To select
or change default electronic customer support resource, follow these steps:
|
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 9 (Select default electronic customer support resource).
|
Note: The displayed list of resources contains only ECS capable communication IOPs. If the
|
communication IOA in this IOP is new, the IOP might be filtered out of the of the list in the Select
|
| Default Electronic Customer Support Resource display. If you cannot see the IOP you want to tag,
disable filtering by pressing the F9 key.
|
6. Use the cursor to select the IOP with the ECS resource.
|
| 7. Select option 1 (Select console IOP)
| 8. Press Enter.
| 9. At the confirmation display, press Enter to confirm your choice.

Installing new hardware for logical partitions

When you install new input/output (I/O) hardware, here are some things you should be aware of:
v A new device is owned by the I/O processor (IOP) to which it is attached.
v A new IOP is owned by the System Bus to which it is attached.
v The primary partition owns a new system bus with own bus shared status. See Changing and switching
I/O resources for information on adding I/O resources to your system. See Changing bus ownership
type for information on how to change bus usage on your system.
v New processors and main storage are available (unassigned) to be assigned to a partition.
v When adding or removing new disk units to your system you may need to clear any residual logical
partition configuration data.

Adding a new logical partition

You can add a new secondary partition to a system that already has logical partitions. If you are creating a
secondary partition on a system without logical partitions, go to the Creating logical partitions page.
Before you add a new logical partition, you should decide where you are going to get the resources for the
new partition. You can either install new resources for the new logical partition, or you can use resources
from existing logical partitions. Before you change your system to add a new logical partition, observe the
following rules:
v The primary partition must have at least 256 MB of main storage. Secondary partitions must have at
least 64 MB of main storage.
v Every logical partition must have at least one processor.
v Every logical partition must have a system console.
