we have not added any disks in quite some time and when we do we always add an entire 16gb raid group at a time, never single disks since it is against netapp policy.
aggregate is 97% full but only with about 8 volumes the least amount of any of our filer. i will try see which volume seems to be most busy/writing
all shelve are on one loop we have no more loop remain to split

we see this alot on one of our 3050's, the disks are 144gb 10k FCAL, we are very concerned:
CPU Total Net kB/s Disk kB/s Tape kB/s Cache Cache CP CP Disk ops/s in out read write read write age hit time ty util 33% 1633 14262 1967 2934 5948 0 0 5 99% 33% : 100% 40% 2036 13033 1799 12622 5279 0 0 5 99% 27% D 100% 58% 3800 16660 2534 13262 24247 0 0 5 99% 100% : 100%
what could be causing this and how can we alleviate it?
are you by chance adding new disks one at a time?
