hi

use SAM to change the parameter. but size must be in bytes.
64K = 64*1024

The way to change kernel tunables is slightly different between OS versions. Which is your HPUX version? Also, note that you need to reboot the system to effect this change.

hi again

which OS version you are using?
There is difference for kernel parameter changing.

in 11iv1 this parameter is static. that means you need reboot.

in 11iv2 this is dynamic.

You can do directly also:

kctune vx_ninode=64kb

vx_ninode is a static tunable that is initialized when VxFS is loaded, so any changes to vx_ninode cannot take effect until the next system reboot.By default, the initial value of vx_ninode is zero; the file system later computes a value based on the system memory size. The following example shows how to change the value of vx_ninode to 64000:

# kctune -s vx_ninode=64000
