Additional Support for Striping and
Mirroring (new)
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.
