Interconnect States
There are two types of Interconnects: an IL (IOP link) that connects one IOP to the other IOP,
and an ESI (Endurance System Interconnect) that connects an IOP to a CE.
The IL cables provide a path for communicating system states and status information. This path
also provides the mirror copy data path.
The Interconnect states are:
Table 2-6 Interconnect States
State Description
Offline Indicates that the Interconnect is not in use by the server but is available for use.
The Interconnect typically transitions to
ready from this state.
Ready Indicates that the Interconnect was activated by an IOP and is waiting for the
component (CE or IOP) at the other end of the interconnect to also activate the
Interconnect. Then, it transitions to
online .
Online Indicates that the Interconnect is in use and communication can be performed
between the server components connected by it. The Interconnect remains in this
state until the server activates the remote component. Then, the Interconnect
transitions to
active .
Active Indicates that the server components on both sides of the Interconnect are active
members of the server configuration. The Interconnect remains in this state until
one of the components is removed from the configuration. Then, the Interconnect
transitions to
offline or ready .
Faulted Indicates that the server removed the Interconnect from operation as a result of one
or more faults that were attributed to the Interconnect. The Interconnect remains in
this state until it is repaired and then enabled (using Endurance Manager).
