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.
