Health status Description
Unknown Metro node cannot determine the device's Health state, or the state is invalid.
Non-recoverable error The device may be out-of-date compared to its mirror (applies only to devices
that are part of a RAID-1 device), and/or metro node cannot determine the Health
state.
Minor Failure One or more children of the device is out-of-date, but will rebuild.
Major Failure One or more children of the device is out-of-date and will never rebuild, possibly
because they are dead or unavailable.
Critical Failure All children of this device are dead or unavailable.
Isolated One or more storage volumes under this mirror is not performing optimally. Metro
node has automatically marked the mirrors as isolated to prevent I/O to them.
Operational status Description
OK The device is functioning normally.
Degraded The device may be out-of-date compared to its mirror. (This applies only to devices
that are part of a RAID-1 device.)
Unknown Metro node cannot determine the device's Operational state, or the state is invalid.
Stressed One or more children of the device is out-of-date and will never rebuild.
Error One or more children of the device is hardware-dead.
Starting The device is not yet ready.
Service status Description
Running The device is functioning normally.
Suspended The device is accepting new I/O; pending I/O requests are frozen. This state could be
due to unreachable, dead, or corrupt storage.
Device component properties
Component Name
The name of the device's component. You can change the name from this dialog box.
Geometry The underlying RAID structure of the device.
Health The overall health of the component.
Health
Indications
A list of reasons for the component's unhealthy state.
Operational
Status
Indicates how the component is functioning in the cluster. See Operational states.
Service Status Indicates whether I/O can proceed on the device. See Service states.
Device properties
Device Name
The name of the top-level device. You can change the name in the properties dialog box. The name must
be unique across clusters.
Geometry The underlying RAID structure of the device.
Virtual Volume The name of the virtual volume created on the device.
Locality Indicates where the device is visible: Local or Remote.
Cluster The name of the cluster to which the device belongs.
