Hi,
filemon gives a lot of information about disks.
It is included in the bos.perf.tools package.
To check if you have bos.perf packages installed:
# lslpp -L bos.perf.*
If not installed , you can find these packages in the
AIX CDs set and install them using SMIT.
Then , type:
# filemon
it will begins to collect information about your
disks. Wait the necessary time that you think is
sufficient to gather all the statistics you need and
type:
# trcstop
Regards,
Antonio Belloni
