WARNING: msgcnt x: mesg 109: V-2-109: failed to tune down
tunable_name to tunable_value possibly due to tunable_object in use,
could free up only up to suggested_tunable_value
■ Description
When the value of a tunable, such as ninode or bufhwm, is modified
using the kctune command, sometimes the tunable cannot be tuned
down to the specified value because of the current system usage. The
minimum value to which the tunable can be tuned is also provided as
part of the warning message.
■ Action
Tune down the tunable to the minimum possible value indicated
by the warning message.
See “Tuning the VxFS file system” on page 45.

WARNING: msgcnt x: mesg 110: V-2-110: The specified value for
vx_bc_bufhwm is less than the recommended minimum value of
recommended_minimum_value.
■ Description
Setting the vx_bc_bufhwm tunable to restrict the memory used by the
VxFS buffer cache to a value that is too low has a degrading effect on
the system performance on a wide range of applications. Symantec
does not recommend setting vx_bc_bufhwm to a value less than the
recommended minimum value, which is provided as part of the
warning message.
■ Action
Tune the vx_bc_bufhwm tunable to a value greater than the
recommended minimum indicated by the warning message.
