SMISA ZDB for EVA in HP-UX LVM Mirroring Configuration
Concepts
Chapter 1 9
SMISA with LVM mirroring functionality expects user LVM configurations to be always
PVG-enabled. This means physical volumes are grouped into two or more different Physical
Volume Groups. Physical volumes belonging to each of these PVGs are from two or more
different EVA arrays. The logical volumes that are to be SMISA backup candidates must be
created with the PVG-strict option to ensure the mirrors reside on different data centers.
Considering only PVG-enabled environments, the following examples illustrate
configurations supported by SMISA with LVM mirroring functionality.
Configuration 1
In this configuration, the backup specification contains, as backup objects, all the logical
volumes in a volume group. Also all the logical volumes (with their extent distributions) are
on different physical volumes within a PVG.
