This message is a section of output from the DISPLAY BUFFERPOOL command, which is part of message DSNB401I.

DSNB456I: Asynchronous I/O delay statistics

The output includes asynchronous I/O delay statistics if all of the following conditions are true:

• You specified the LSTATS option on the DISPLAY BUFFERPOOL command.
• The buffer pool is an active buffer pool.
• The values of the asynchronous I/O delay statistics are not zero.

These asynchronous I/O delay statistics are reported for a data set for an open table space or index space that is associated with the buffer pool. The values that are listed are the statistics that were gathered since the last display for the data set.

The relevant table space or index space is identified in either line DSNB464I or line DSNB465I. The relative data set within the table space or index space is identified in line DSNB466I.

avd

The average I/O delay in milliseconds for pages in the data set.

mxd

The maximum I/O delay in milliseconds for pages in the data set.

tpg

The total number of pages that are read or written for the data set.

tpg

The total number of I/O operations that are issued for the data set.
