Symptoms

A consistent copy is attempted, but a timeout occurs due to existing SRDF/A R2 invalid tracks when specifying ACTIVATE (CONSISTENT(YES)) using Mainframe Enablers SnapVX. The return code (RC) from the ACTIVATE is 8 (MAXRC setting was 4), but an inconsistent copy is still created and activated. 

This issue only occurs in Mainframe Enablers 10.0.0.

Cause

This is due to a software issue.

When the SRDF/A group fails to suspend, it performs an ACTIVATE of the created snapshots and did not terminate the inconsistent snapshots.
