Field Description
Name
Name of storage volume.
I/O Status
alive - I/O is proceeding normally on the storage volume.
dead - Metro node has marked the storage volume as dead;
I/O cannot proceed on the storage volume. This can happen
when a certain number of I/Os to the storage volume fails.
unreachable - The storage volume is unreachable.
Operational Status
ok - The storage volume is functioning normally.
degraded - The storage volume may be out-of-date
compared to its mirror. (This state applies only to a storage
volume that is part of a RAID 1 Metadata Volume.)
unknown - Metro node cannot determine the storage
volume's Operational state, or the state is invalid.
error - Metro node has marked the storage volume as
hardware-dead.
starting - The storage volume is not yet ready.
lost communication - The storage volume is
unreachable.
Health State
degraded - The extent may be out-of-date compared to
its mirror (applies only to extents that are part of a RAID 1
device).
ok - The extent is functioning normally.
non-recoverable-error - The extent may be out-of-
date compared to its mirror (applies only to extents that are
part of a RAID 1 device), and/or the Health state cannot be
determined.
unknown - Metro node cannot determine the extent's
Operational state, or the state is invalid.
critical failure - Metro node has marked the storage
volume as hardware-dead.
