Additional Support for Striping and Mirroring

new at 11i
original release

Logical Volume Manager (LVM) now supports striping and mirroring for shared volume groups. Previously under HP-UX 11.0, a volume group could not be activated in shared mode if any of its logical volumes were striped or mirrored. This restriction has now been lifted.

Shared volume groups are provided to support ServiceGuard Oracle Parallel Server (OPS), so this change only affects customers using OPS. Those customers are now free to stripe their logical volumes (to improve throughput) or mirror them (for higher availability).

	NOTE: Where performance is limited by I/O throughput, striping may help.
