Creating a virtual Internet Protocol (IP) resource Choose an available IP address as the virtual IP for the Data Server Manager service. Using this virtual IP  makes Data Server Manager switching between the master and backup nodes transparent to users.  Regardless of the Data Server Manager service active on either node, users see only the virtual IP.  Complete these steps: Choose an available IP (9.111.97.120 is used in this example) as the virtual IP. Next create the virtual  1. IP resource on the master node (root authority needed): [root@dsm-master init.d]]# mkrsrc IBM.ServiceIP  NodeNameList="{’dsm-master’,’dsm-backup’}" Name="dsmIP"  NetMask=255.255.255.0 IPAddress= 9.111.97.120  ResourceType=1 [root@dsm-master init.d]# lsrsrc -s "Name=’dsmIP’" IBM.ServiceIP  Run the  lsrsrc IBM.NetworkInterface  command. This command shows that the IP resource is  bound on  eth4  (this variable is used later). [root@dsm-master init.d]# lsrsrc IBM.NetworkInterface Figure 13 shows the  lsrsrc IBM.NetworkInterface  command output. 10 Setting Up IBM Data Server Manager as a Highly Available Service
