To change system tunables using SMIT, enter the following command:

# smit vxvm

and select "Change / Show VxVM Tunables" from the menu.

DMP tunables are set online (without requiring a reboot) by using the vxdmpadm command as shown here:

# vxdmpadm settune dmp_tunable=value

The values of these tunables can be displayed by using this command:

# vxdmpadm gettune [dmp_tunable]
