Microcode issue impacting concurrent copy

A known open microcode defect causes a counter on the box to reach its maximum limit without clearing itself. This counter keeps track of active sessions on a control unit (in hardware). There is a limit to how many active sessions (XRC and CC) you can have on a control unit, so when this counter is maxed out, the client is unable to execute more Concurrent Copy sessions. This issue is regarding the 5695DF117 System Data Mover (SDM) component.

Symptoms

Error messages reported:

ANTPC2 messages flood the LOGREC, one for every CC request, which can be hundreds.

How to investigate

This issue requires the user to take a hardware statesave on the box. A statesave is like taking a dump, but it also performs "checks and balances".
The user should open a Hardware PMR to request the statesave.
