Servant Facility in an SSI Complex

We strongly recommend that you configure the Servant Facility in an SSI environment. This configuration simplifies the execution of product commands which execute long running minidisk operations such as formatting and copying. The product server launches servant virtual machines on any member system, as they are needed. Without the servant facility, the format and copy operations execute in the virtual machine that issues the command. The issuer must then run on a specific member system when the minidisk involved is reachable only from that member. If the servant facility is used, the command issuer is not tied to a particular member but can run on any member. This arrangement simplifies the operation of the SSI complex.
