I/O Pools

Use this window to perform the following tasks:

An I/O pool is a group of I/O adapters that can be taken over and used by any of a specified group of logical partitions without the active intervention of the Hardware Management Console (HMC).

If you add an I/O device to a partition profile, and the I/O device belongs to an I/O pool, then the I/O pool is added automatically to the partition profile. You cannot remove the I/O pool from the partition profile unless you remove the I/O device from the I/O pool or you remove the I/O device from the partition profile.

When you activate the partition profile, the managed system automatically adds the I/O pools associated with the partition profile to the logical partition. You can remove an I/O pool from the logical partition only if the logical partition has no I/O devices in that I/O pool.

Changes that you make to the I/O pools of a partition profile do not affect a running logical partition until you shut down and restart the logical partition using the changed partition profile. Similarly, changes that you make to the I/O pools of a logical partition do not affect the active partition profile for that logical partition.

The number of pools in the I/O Pools list cannot exceed the number shown in the Number of I/O pools allowed field.
