What is the right the procedure to set the numfsbufs parameter?
The current value of the parameter is 196
App_Server:>ioo -o numfsbufs numfsbufs = 196
The details of the server (prtconf command) are at http://dpaste.com/1317430/
We want to change the value of numfsbufs parameter to 512
This is based on the analysis of increasing value of I/O blocked
52534 pending disk I/Os blocked with no pbuf 0 paging space I/Os blocked with no psbuf 2228 filesystem I/Os blocked with no fsbuf 0 client filesystem I/Os blocked with no fsbuf 313699 external pager filesystem I/Os blocked with no fsbuf
The command to do this is
ioo -p -o numfsbufs=512
What I am not sure about is how to handle the mount/unmount of Volume Groups
Do i need to mount and unmount each and every file system? Or can i just restart the server after setting this variable and it will take care of itself
The link at http://dpaste.com/1317412/ shows the various volume groups.
Please guide as I am confused what the procedure should be.
The system administrators are asking a detailed set of instruction and hence I am trying to work out a document detailing the various steps.
