HP-UX 11i September 2001 Release Notes

Chapter 9
143
9 New and Changed Disk and File
Management Features
Additional Support for Striping and Mirroring (new at
11i original release)
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.
