idtune(1M)                                                       idtune(1M)

NAME
     idtune - attempts to set value of a tunable parameter

SYNOPSIS
     /etc/conf/bin/idtune [-f] [-m] name value

DESCRIPTION
     This script attempts to set the value of a tunable parameter. The tun-
     able parameter to be changed is indicated by name. The desired value
     for the tunable parameter is value.

     If there is already a value for this parameter (in the stune file),
     the user will normally be asked to confirm the change with the follow-
     ing message:

          Tunable Parameter name is currently set to oldvalue.
          Is it OK to change it to value? (y/n)

     If the user answers y, the change will be made. Otherwise, the tunable
     parameter will not be changed, and the following message will be
     displayed:

          name left at oldvalue.

     However, if the -f (force) option is used, the change will always be
     made and no messages will ever be given.

     If the -m (minimum) option is used and there is an existing value
     which is greater than the desired value, no change will be made and no
     message will be given.

     If either the existing value or the desired value is a formula, then
     the -m option will be ignored.

     If system tunable parameters are being modified as part of a device
     driver or application add-on package, it may not be desirable to
     prompt the user with the above question. The install script for the
     add-on package may chose to override the existing value using the -f
     or -m options. However, care must be taken not to invalidate a tunable
     parameter modified earlier by the user or another add-on package.

     In order for the change in parameter to become effective, the Reliant
     UNIX system kernel must be rebuilt and the system rebooted.

DIAGNOSTICS
     The exit status will ne non-zero if errors are encountered.
