Managing physical I/O adapters

You can view and change physical I/O adapter assignment for a partition by using the Hardware Management Console (HMC).

You can dynamically add, remove, and move physical I/O devices and slots, to and from running partitions, by using an HMC. You can share infrequently used I/O devices, such as optical disk drives among multiple partitions.

You can specify that I/O devices or slots are required for a partition. If you specify that an I/O device or slot is not required, the I/O device or slot can be shared with other partitions, or the I/O device or slot is optional. If you specify that an I/O device or slot is required (or dedicated) and if the I/O device or slot is unavailable, or is in use by another partition, you cannot activate the partition.

Note: If resources are moved dynamically, the configuration change is temporary and is not reflected in the partition profile. All configuration changes are lost when the partition profile is next activated. If you want to save your new partition configuration, either change the partition profile or save the partition configuration to a new partition profile.

You can specify a timeout value in the Timeout field. You can also click the Force option to force a particular operation to be performed on the logical partition immediately.
