Note:  The warning appeared only because this test environment is composed only of two  hosts on the host group. To list the blacklist host that is configured on VM rt11004, run the command  ksysmgr query  vm rt11004 , as shown in Example 3-66. Example 3-67 shows how to delete the blacklist policy from VM rt11004. The  failover priority  policy specifies the order of processing multiple VMs restart operations.  For example, if a host fails and all the VMs must be relocated to other hosts on the host group,  the priority of the VM determines which VM is processed first. The supported values for this  attribute are  High ,  Medium , or  Low . You can set this attribute at the VM level only. You must  specify the UUID of the VM if you have two or more VMs with the same name. By default, all  VMs on the host group have a priority of  Medium . To set the failover priority, run the following command: 306  Implementing IBM VM Recovery Manager for IBM Power Systems Example 3-68 Setting the VM rt11001 to High priority Example 3-67 Deleting the blacklist host from VM rt11004 Example 3-66 Checking the blacklist policy on VM rt11004 # ksysmgr query vm rt11004 Name: rt11004 UUID: 4FCD724B-8407-4945-A973-C25C4CA69A94 State: INIT Host: rt11-8286-42A-0607585 Priority: Medium VM_failure_detection_speed: normal HA_monitor: enable Homehost: rt11-8286-42A-0607585 Blacklist_hosts: rt12-8286-42A-2100E5W VM_status: NO_OPERATION_IN_PROGRESS Version_conflict: No # ksysmgr modify vm rt11004 blacklist_hosts=rt12-8286-42A-2100E5W policy=delete For VM rt11004 attribute(s) 'blacklist_hosts', 'policy' was successfully modified. ksysmgr modify vm name1[,name2,...] | filepath=filepath priority=high|medium|low # ksysmgr modify vm rt11001 priority=High For VM rt11001 attribute(s) 'priority' was successfully modified.
