IOP States The IOP states are: Table 2-5 IOP States State Offline Ready Initializing Initialized Joining Active Faulted Disabled Shutdown Description Indicates that the IOP is not available for use in the server. The IOP is typically in this state if it is powered down or if it cannot communicate with other IOPs because the Interconnects between the IOP and the Endurance server are not usable. Indicates that the IOP is ready to become an active member of the server configuration. The IOP remains in this state until it joins with another IOP, or until it boots the CE. Then, the IOP transitions to active. Indicates that the IOP is in the process of agreeing on the states of all server components and parameters with the second IOP. As this process completes, the IOP transitions to active or joining. Indicates the transitional state an IOP enters at the completion of the IOP initialization process just before it begins joining with the second IOP. Then, the IOP transitions to the joining state. Indicates that the IOP is in the process of being joined into the active server configuration. During this process, all providers perform initialization with their peers on the remote IOP, and the IOP is activated into the server. Then, the IOP transitions to active. Indicates that the IOP is a fully active member of the server configuration. In this state, the IOP serves I/O requests from any active CE(s) and participates fully in all fault handling events. The IOP remains in this state until it is shutdown, disabled, or removed from the configuration as the result of a system failure. Indicates that the server removed the IOP from operation as a result of one or more faults that were attributed to the IOP. The IOP remains in this state until it is repaired and an Endurance Manager IOP Enable command is issued. Indicates that you issued an Endurance Manager IOP Disable command to remove the IOP from operation. The IOP remains in this state until it is enabled using an Endurance Manager IOP Enable command. Indicates that the IOP is being shut down either because you issued an Endurance Manager IOP Shutdown command, or because a fault occurred that requires the server to remove the IOP from the configuration. The IOP remains in this state only as long as it takes to properly shut down the Windows operating system on the IOP. Endurance Overview 2-15

IOP States
The IOP states are:
Table 2-5
IOP States
State
Description
Offline
Indicates that the IOP is not available for use in the server. The IOP is typically in this
state if it is powered down or if it cannot communicate with other IOPs because the
Interconnects between the IOP and the Endurance server are not usable.
Ready
Indicates that the IOP is ready to become an active member of the server
configuration.
The IOP remains in this state until it joins with another IOP, or until it
boots the CE.
Then, the IOP transitions to
active
.
Initializing
Indicates that the IOP is in the process of agreeing on the states of all server
components and parameters with the second IOP.
As this process completes, the
IOP transitions to
active
or
joining
.
Initialized
Indicates the transitional state an IOP enters at the completion of the IOP initialization
process just before it begins joining with the second IOP.
Then, the IOP transitions to
the
joining
state.
Joining
Indicates that the IOP is in the process of being joined into the active server
configuration.
During this process, all providers perform initialization with their peers
on the remote IOP, and the IOP is activated into the server.
Then, the IOP transitions
to
active
.
Active
Indicates that the IOP is a fully active member of the server configuration.
In this
state, the IOP serves I/O requests from any active CE(s) and participates fully in all
fault handling events.
The IOP remains in this state until it is shutdown, disabled, or
removed from the configuration as the result of a system failure.
Faulted
Indicates that the server removed the IOP from operation as a result of one or more
faults that were attributed to the IOP. The IOP remains in this state until it is repaired
and an Endurance Manager IOP Enable command is issued.
Disabled
Indicates that you issued an Endurance Manager IOP Disable command to remove
the IOP from operation. The IOP remains in this state until it is enabled using an
Endurance Manager IOP Enable command.
Shutdown
Indicates that the IOP is being shut down either because you issued an Endurance
Manager IOP Shutdown command, or because a fault occurred that requires the
server to remove the IOP from the configuration. The IOP remains in this state only
as long as it takes to properly shut down the Windows operating system on the IOP.
