Removing a physical I/O adapter from a partition
You can dynamically remove a physical I/O slot, the adapter, and devices that are connected to that slot by using the Hardware Management Console (HMC). You can reassign the physical I/O adapter to other partitions.
Before you begin
Ensure that the devices that are attached to the managed system through the physical I/O slot that you want to remove are not running, by using the operating system commands.
Attention: The dynamic removal of a physical I/O slot that controls
disk drives can cause unpredictable results, such as partition failure
or loss of data.
Consider the following conditions when you
remove a physical I/O slot from a Linux® partition:
- A Linux distribution that supports dynamic partitioning is installed on the Linux partition. Distributions that support dynamic partitioning include SUSE Linux Enterprise Server 9, and later.
- The DynamicRM tool package is installed on the Linux partition. To download the DynamicRM tool package, see the Service and productivity tools for Linux on POWER® systems website.
