Figure 2-6 KSYS in an RMC framework The ksysmgr utility As introduced in 3.5, “Configuring VM Recovery Manager HA” on page 281,  ksysmgr represents internally the various entities it manages as objects of a predefined type CLASS,  on which an ACTION can be performed. These objects are, in fact, just RMC resources of a  specific RMC resource class, with predefined attributes and actions. Most of the  ksysmgr commands start RMC-provided utilities that are revealed in the  ksysmgr  log  /var/ksys/log/ksysmgr.log . The excerpt in Example 2-13 shows a sequence of actions that  were logged during our KSYS cluster creation by the  ksysmgr add ksyscluster  command.  Steps in the sequence start RMC utilities such as  preprpnode ,  mkrpdomain , and  lsrsrc .
