I have a client who is experiencing something rather strange.
Every few
seconds, and not with any particularly regularity, "topas" will
report a
spike in disk writes, maxing out one or more disks to 100%
utilization. CPU
utilization, on the other hand, remains nominal or only slightly
elevated.
When this happens, the world stands still - literally - as user
screens
freeze up until several seconds after the disks have gone back to
normal
load. Is there an AIX utility that can be used to track which specific
processes are reading or writing disk? This would be very helpful in
determining what (or who) specifically is triggering this activity.
