Using High Availability Monitors (June 2003)

Monitoring Disk Resources
HA Disk Monitor Reference
Chapter 2 33
NOTE If the logical volume is in an inactive volume group, the HA Disk Monitor
cannot determine if the data can be accessible.
Table 2-3 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_DOWN, you would specify greater than or equal
to 3 (>=3).

Condition Value Interpretation
UP 1 All logical volumes are accessible and all data is
accessible.
INACTIVE 2 The volume group is inactive. This could be
because:
• The volume group is active in exclusive mode
on another node in an ServiceGuard cluster.
(This is not valid for clusters running
ServiceGuard Extension for RAC, because it
can support a volume group being active on
more than one node.) Note that ServiceGuard
does allow a volume group to be active in
read-only mode, if it is already active on
another node.
• The volume group is made inactive using
vgchange -a n for maintenance or other
reasons.
• There is no quorum of active physical volumes
at system boot. For example, not enough disks
in the volume group were working.

3 The last time the inactive volume was activated, it
was DOWN. At least one logical volume in the
volume was inaccessible.
