Logical Volume Status
Logical volume status gives you status on each logical volume in a
volume group. While the lv_summary gives you information on whether
data in a volume group is available, the lv/status/ lvName gives you
information on whether specific logical volumes have failed.
Table 2-4 lists how conditions compare in logical operations. You specify
the logical operation in the monitor request parameters portion of the
monitor request. For example, to create a request that alerts you when
the condition is INACTIVE, you would specify greater than or equal to 2
(>=2).
When configuring requests from the SAM interface, use a wildcard (*) in
place of lvName to monitor all logical volumes in a volume group.
If you split off mirrors from your mirrored configuration, you will see
new logical volume resource instances when the split mirror is created.
DOWN 4 At least one logical volume in the volume group
reports a status of either INACTIVE or DOWN. Note
that an inactive logical volume in an active volume
group is rare, but possible. See “Logical Volume
Status” on page 34.

UP 1 All logical volumes are accessible and all data is
accessible.
INACTIVE 2 The logical volume is inactive.
DOWN 3 The logical volume is DOWN. A complete copy of the
data is not available for this logical volume.
