Changing the values of tunables

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

# smit vxvm

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.
