Tuning VxVM
410 VERITAS Volume Manager Administrator’s Guide
You can also change the number of copies for an existing group by using the vxedit set
command (see the vxedit(1M) manual page). For example, to configure five
configuration copies for the disk group, bigdg, use the following command:
# vxedit set nconfig=5 bigdg
Changing Values of Tunables
Tunables are modified by using SAM or the kctune utility. Changed tunables take effect
only after relinking the kernel and booting the system from the new kernel.
The values of system tunables can be examined by selecting Kernel Configuration >
Configuration Parameters in SAM.
