Determining Device States
SERVICING SPECIAL The object is being serviced or used by a
privileged process and is inaccessible to user
processes.
TEST The object is reserved for exclusive testing.
STARTED The object is logically accessible to user
processes.
STARTING The object is being initialized and is in transition to
the STARTED state.
STOPPED CONFIG-ERROR The object is configured improperly.
DOWN The object is no longer logically accessible to user
processes.
HARDDOWN The object is in the hard-down state or is physically
inaccessible due to a hardware error.
INACCESSIBLE The object is inaccessible to user processes.
PREMATURE-
TAKEOVER
The backup input/output (I/O) process was asked
to take over for the primary I/O process before it
had the proper information.
RESOURCE-
UNAVAILABLE
The input/output (I/O) process could not obtain a
necessary resource.
UNKNOWN-
REASON
The input/output (I/O) process is down for an
unknown reason.
STOPPING The object is in transition to the STOPPED state.
No new links are allowed to or from the object.
Existing links are in the process of being deleted.
SUSPENDED The flow of information to and from the object is
restricted. (It is typically prevented.) A subsystem
must clearly distinguish between the type of
information that is allowed to flow in the
SUSPENDED state and that which normally flows
in the STARTED or STOPPED state. In the
SUSPENDED state, the object must complete any
outstanding work defined by the subsystem.
SUSPENDING The object is in transition to the SUSPENDED
state. The subsystem must clearly define the
nature of the restrictions that this state imposes on
its objects.
UNKNOWN The object’s state cannot be determined because
the object is inaccessible.
