Error description
TPC-R is not handling the HyperSwap suspend properly which caused one of the H1-H2 pairs not in' 'target available' state, which causes an 0F12 error. TPC-R interprets the pairs as simplex and attempts to try to recreate the pprc pair, but they are not simplex. Appears there is a race condition between the thread processing the HyperSwap and the thread processing the suspend event. As a result of this, the pair ends up suspended instead of Target Available. Then, when the start command is issued, since the pair is suspended, TPC-R issues a resync instead of a failback command. This results in first a 0x0F11, followed by a 0x0F12. RECREATE STEPS: Run hyperswap command to target ________________________________________________________________ DB2 Version used for Server: The defect is against component: 5608TRMZ0 Server/Manager build/release (TPC): 4.2.2.x Agent build/release (TPC): Server/Manager (OS): Z/oS Agent (OS): ________________________________________________________________ Problem as described by customer: IWNR2108E with return code 0F12 Initial customer impact (low/med/high): med
