HP 3PAR InForm OS 3.1.1 MU2 Patch 18 Release Notes (QL226-96677, August 2012)

This release notes document describes the modifications and known issues for Patch 18 (P18). The
application of this patch is intended for HP 3PAR InForm OS 3.1.1.410 (MU2).
This patch ensures that all valid data blocks of a read-write snapshot (RWSS) with thin-provisioned
base volumes (TPVV) are copied correctly. It resolves the remote copy issue for initial synchronization
of RWSS with TPVV. The patch also adds robust error handling to the Logical Disk (LD) tuning phase,
and compacts any LDs remaining after the tuning is completed.
