Compatibility Note - HP -UX 11i Administrator's Manual

Compatibility Note

Releases prior to HP-UX 1 1i v3 only support striped or mirrored logical volumes and do not support
combination of striped and mirrored logical volumes. If a logical volume using simultaneous
mirroring and striping is created on HP-UX 1 1i v3, attempts to import or activate its associated
volume group fails on a previous HP-UX release.
To import the volume group with striped and mirrored logical volume to releases prior to HP-UX
1 1i v3, you must remove the incompatible logical volumes or reduce them to no mirrors.
NOTE: Striped and mirrored logical volume is supported on HP-UX 1 1i v2 with the PHCO_36744,
PHKL_36745 and PHCO_36746 patches. With these patches or superseding patches installed
on a HP-UX 1 1i v2 system, you can successfully import and activate a volume group with striped
and mirrored logical volume created on HP-UX 1 1i v3.
