Logical Volume Status
Logical volume status gives you status on each logical volume in a volume group.
While the lv_summary tells whether data in a volume group is available, the
lv/status/lvName will tell you whether specific logical volumes have failed.
The value in Table 2-4 is used by the disk monitor to determine how conditions
compare in logical operations. For example, you may create a request that alerts you
when the condition is greater than or equal to INACTIVE. The numeric value allows
you to tell which conditions qualify.
Table 2-4 Interpreting Logical Volume Status
When configuring requests from the SAM interface, a wildcard (*) may be used 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.
Resource Name /vg/vgName/lv/status/lvName
Condition Value Interpretation
UP 1 All logical volumes are accessible, 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.
