To change system tunables using SMIT, enter the following command:
and select "Change / Show VxVM Tunables" from the menu.
DMP tunables can also be set 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]
The vxdmpadm command also allows you to configure how DMP responds to I/O errors at the level of the paths to individual arrays.
See "Administering DMP using vxdmpadm" on page 127.
