Hello Hasan,
I had added the new tunable through the following command:

# kctune -u tunable=value
eg. # kctune -u aio_iosize_max=0

checked also with SAM everything is went well
Now,should I mark it default ?
what will be the result after reboot ?

Hi Sachin,

> Now,should I mark it default ?

If you are assigning it as a default that means you are allowing system to choose tunable value on its own.
See deatils on man page.
tunable=Default The tunable will be set to its default state.
