About VCS tunable parameters

VCS has some tunable parameters that you can configure to enhance the performance of specific features. However, Veritas Technologies recommends that the user not change the tunable kernel parameters without assistance from Veritas Technologies support personnel. Several of the tunable parameters preallocate memory for critical data structures, and a change in their values could increase memory use or degrade performance.

Warning:

Do not adjust the VCS tunable parameters for kernel modules such as VXFEN without assistance from Veritas Technologies support personnel.
