I am using netapp 980C filers . during midnight to 01:30 AM (for 1:30
minute) , filer uses the high cpu % its cpu utilization would reach up
99% . i want to know during these period which process/activities are
running/execuate . how would i know from the filer..DFM has configured
on the filer.
Pl. let me know is there command which give perfomace report (its like
iostat, prstat on solaris).

You can run 'sysstat -x -c 10 1' on the filer (or rsh from an admin
host) to get some decent info. This command will tell you if it's
disk, IOPS, througput, tape backups, etc.
Also, something much more advanced, is 'statit -b' to start the
collection and 'statit -e' to end it. Do not run this more than 10
seconds and, if possible, do it from rsh so that you can re-direct the
output. by default it goes to stdout, and it's alot of information.
You may need to send it to NetApp for analysis but there are a few
things that are obvious. If you want you can post the output and I
can tell you what I see.
Btw, this command has to be run under 'advanced' or 'diag' mode.
From an rsh:
rsh <filer> "priv set diag; statit -b" (the "'s are needed)

Just to add on one thing. Also grap process statstics.
rsh <filer> "priv set advanced; ps -c 4 (process those are using
more than 4% of cpu)
This may give some clue.
