APAR status

• Closed as program error.

Error description

• When using the Tivoli Software Automation (TSA) product to
  automate DB2 HADR failovers, and there is exactly 1 network
  interface card (NIC) in use per machine, and the NIC is
  marked inactive (down), then transaction processing might not be
  stopped completely prior to promoting the former HADR standby
  as the new HADR primary.
  

Local fix

• For existing customers running TSA automation with HADR, they
  can execute the following TSA command to ensure transaction
  processing is stopped completely prior to an attempted failover.
  (This command must be run as root at any node in the
  cluster domain):
  # chrsrc -s 'Name like "db2_%" ' IBM.Application
  ProtectionMode=1
  
  For customers who will setup the TSA HADR cluster domain with
  the fix included in this APAR, it is not necessary to run this
  command. The DB2 resources will be created with the
  ProtectionMode=1 attribute set.
