Hi,
My previous question:
We are using Solaris 2.6. I have a Sun system (an NFS
client) having CPU problem now. The system/kernel
processes have consumed 50% to 70% of the CPUs. Here
is the info from TOP: "CPU states: 7.0% idle, 20.0%
user, 72.9% kernel, 0.1% iowait, 0.0% swap Memory:
1024M real, 479M free, 152M swap in use, 1639M swap
free". The user processes seem fine in either 'top' or
'/usr/ucb/ps -aux', and they don't consume much CPU.
My new question:
>From the following output, it seems that disks 'nfs30'
and 'nfs31' have some I/O distribution problems. Is it
correct? How can I prove it? The system uses Veritas
Volume Manager.
# iostat -xc 5
