IT11801: PUREAPPLICATION SYSTEM: HIGH AVAILABILITY ON POWER COMPUTE NODESFAILS TO MIGRATE ALL VIRTUAL MACHINE FROM FAILING COMPUTE NODE

IBM PureApplication System Version 2.1.2.0

APAR status

• Closed as program error.

Error description

• PureApplication System
  -
  The High Availably function on the Power compute nodes fails to
  move all the virtual machines (VMs) from a failing compute
  node to an available working compute node.
  
  When a compute node has a fatal hardware failure, the system is
  supposed to detect the failure and automatically move the VMs
  to another available compute node in the cloud group.
  
  The moved VMs will be automatically started
  if the cloud group has enough compute resource to run the
  virtual machines.
  

Local fix

Problem summary

• In some coditions the hardware failure is difficult to
  detect. Code needs to be added to check the status of
  the logical partitions (LPARs) on a compute node. If every
  LPAR is "Not Available", then initialize the compute node.
  This will activate the high availability process of
  moving the virtual machines to another available compute node
  in the cloud group.
  

Problem conclusion

• A code fix is being provided in PureApplication System
  version 2.1.2.0.
  

Temporary fix
