zaxxon was of course correct to point this counter out, but i would like to explain it a bit more, for completeness:
This counter (and similar ones, like "paging space I/Os blocked with no psbuf", etc.) are collected from boot time. Therefore the value itself is not that interesting but its change over time is.
A high value which doesn't (or does hardly) change over time hints to a problem in the past which is not occurring right now. That doesn't necessarily mean that the problem is solved, just its symptom is not occurring. Always take the number one advice of performance monitoring/tuning to heart: a problem is not solved when its symptom cannot be observed, but only when the symptom doesn't occur any more and you understand why this is so!
If you have to trace this or a similar counter always take snapshots over some extended period (every hour, every day, ...) and compare. Notice how much the counter increases - that is: the order of magnitude of the increment. If the counter increases in the tens over a day everything is ok, if it increases in the hundreds over an hour you have to investigate, if the increment is even higher you have to act immediately.
Looks like a good sign. As bakunin said - just have a look on it maybe twice every week or have a script informing you every day in the morning as a report. Anyway it might be a good idea to split your storage for smoother performance.
zaxxon yes and thanks again to you and to everybody who tried to help me :-) as soon as we make storage upgrade I will allocate DB2 containers to separate File Systems.. Let's than see what will happen :-)
My comments:
it’s statistics about filesystems jfs
It’s statistics about filesystems nfs, veritas, …
It’s statisctics about filesystems jfs2
Conclusions are obvious.

you have disks on SAN. by NFS or FiberConnect(etherConnect)
It's maybe problem with tcp.
When will be the problem do
You can test the connect make big transfer from server to dysk, better to same disks.
Well we have finished upgrading of DS8000 and I located DB2 containers on separate filesystems.. the performance is just a perfect!!! thanks to everybody
