Process Resource Manager (PRM) Disk Bandwidth Control

This release allows Process Resource Manager (PRM) to report and control disk I/O bandwidth per LVM device and VxVM device. (VxVM is the VERITAS Volume Manager.) Based on user-configured priorities, PRM will reorder LVM or VxVM disk queues to enforce the percentage of disk bandwidth a PRM group receives in an I/O-constrained environment. The functionality is documented in the PRM manpages.
