Changing logical partition Input/Output priority queuing values
Use the Change Logical Partition I/O Priority Queuing task to set the minimum and maximum I/O priority queuing values for logical partitions.
Note: Minimum I/O Priority and Maximum I/O Priority should
be specified as a range of values that give software some ability
to make choices. All logical partitions in a given LPAR cluster should
be given the same range of values so that Workload Manager can optimize
I/O throughput across the LPAR cluster.
If the software in the logical partition does not have an understanding of I/O Priority Queuing, the system programmer should set the Minimum and Maximum I/O priorities to the same value. The value chosen is assigned to that logical partition as a constant priority value relative to all other logical partitions. This way even logical partitions that do not employ IRD technologies can benefit from this support.
