does the same - display/count the used asynchronous I/O servers. Note, though, that you have to deduct 1 from the result (the server process). Also note the correclation with the number of CPUs: The number you enter on the "chdev"-command line with the "maxservers" attribute is the number of servers
per CPU. On an 8-way system the command
chdev -l aio0 -P -a maxservers=10
will cause (a maximum of) 81 aio servers (1 server process and 80 worker processes) to come into life.
I hope this helps.
