HA Disk Monitor Reference
The HA Disk Monitor reports information about the physical and logical
volumes configured by LVM (Logical Volume Manager). Anything not
configured through LVM cannot be monitored fromthe HA Disk Monitor.
Monitored disk resources are:
• /vg/ vgName /pv_summary, a summary status of all physical volumes
in a volume group
• /vg/ vgname /pv_pvlink/status/ deviceName , the status of a given
physical volume or PV links in a volume group
• /vg/ vgName /lv_summary, a summary status of all logical volumes in a
volume group
• /vg/ vgName /lv/status/ lvName , the status of a given logical volume in a
volume group
• /vg/ vgName /lv/copies/ lvName , the number of copies of data available
in a volume group
Monitoring both the physical and logical volumes allows you to detect
failures in volume groups (both active and inactive) and in logical
volumes. With these warnings, you can correct hardware problems that
put node, application, or data availability at risk.
