Dynamically moving an I/O processor

 

A logical partition controls all devices connected to an IOP. You cannot switch one I/O device to another logical partition without moving the ownership of IOP.

On a shared bus, you can move IOPs from a logical partition without restarting the server. All resources (IOAs and devices) that are attached to the IOP cannot be in use when you move an IOP from a logical partition.

To move an I/O processor from one logical partition to another partition using My Connections, follow these steps:

1. Ensure that any devices attached to the I/O processor you want to move are not busy. The devices should be varied off and listed as unavailable hardware.

2. In iSeries™ Navigator, expand My Connections or your active environment.

3. Select the primary partition of the system.

4. Expand Configuration and Service and select Logical Partitions.

5. Right-click the Logical Partition and select Configure Partitions. You are now working in the Configure Logical Partitions window.

6. Select the partition that has the I/O processor you would like to move.

7. Right-click the I/O processor you want move, and select Move.

To move an I/O processor from one logical partition to another partition using the service tools window, follow these steps:

1. Ensure that any devices attached to the I/O processor you want to move are not busy. The devices should be varied off and listed as unavailable hardware.

2. In iSeries Navigator, select My Connections or your active environment.

3. Select Open iSeries Navigator service tools window in the Taskpad window. If the Taskpad window is not displayed, select View and select Taskpad.

4. Enter the IP address of the service tool network interface to which you want to connect. Click OK.

5. You will be prompted for your Service Tools User ID and user password.

6. Expand the system name select Logical Partitions.

7. Right-click the logical partition and select Configure Partitions. You are now working in the Configure Logical Partitions window.

8. Select the partition that has the I/O processor you would like to move.

9. Right-click the I/O processor you want move, and select Move.

To move an I/O processor from one logical partition to another using Management Central, follow these steps:

1. Ensure that any devices attached to the I/O processor you want to move are not busy. The devices should be varied off and listed as unavailable hardware.

2. In iSeries Navigator, expand Management Central.

3. Expand Systems with Partitions.

4. Select the physical system that has the logical partition with which you want to work.

5. Right-click the logical partition and select Configure Partitions . You are now working in the Configure Logical Partitions window.

6. Select the partition that has the I/O processor you would like to move.

7. Right-click the I/O processor you want move, and select Move.

• Changing the ownership of a bus
  A logical partition can own a system input/output (I/O) bus in one of two ways. It can own bus dedicated, or it can own bus shared.
