Adding physical I/O devices and slots dynamically
You can dynamically add a physical I/O slot (and the adapter and devices that are connected to that slot) to a running logical partition using the Hardware Management Console (HMC). This allows you to add I/O capabilities to a running logical partition without having to shut down the logical partition.
A Linux logical
partition supports the dynamic addition of physical I/O slots only
if the following conditions are met:
- A Linux distribution that supports dynamic partitioning is installed on the Linux logical partition. Distributions that support dynamic partitioning include SUSE Linux Enterprise Server 9, and later.
- The DynamicRM tool package is installed on the Linux logical partition. To download the DynamicRM tool package, see the Service and productivity tools for Linux on POWER® systems Web site.
You cannot add physical I/O devices and slots to logical partitions that use shared memory. You can assign only virtual adapters to logical partitions that use shared memory.
To dynamically add a physical I/O slot to a running logical
partition by using the HMC,
complete the following steps:
- In the navigation pane, open , and click the managed system on which the logical partition is located.
- In the work pane, select the logical partition, click the Tasks button, and click .
- Select the physical I/O slot that you want to add to the logical partition.
- Click OK.
