Caution: If an IMC Istate is copied from an IOC module to the IMC
module and that IState contains a different user list, ensure that the
<uids> and <pids> are known to avoid being locked out of the
system.
The IOC Module is Replaced in a Single-IOC System – In this case, copying the
IOC Istate to the IMC module, replacing the IOC module, then copying the IOC
Istate back to the replacement IOC module effectively provisions the
replacement IOC module with the settings of the IOC module it replaced.
Both IOC Modules are Replaced Concurrently – In this case, copying the IOC
Istate from the active IOC module to the IMC module, replacing both IOC
modules, then copying the IOC Istate back to the replacement IOC modules
effectively provisions the replacement IOC modules with the settings of the IOC
modules they replaced.
Notes:
IOC modules are capable of transferring their Istates to each other
automatically. When both IOC modules are to be replaced, it might
desirable to allow this transfer to occur automatically:
Replace the IOC module that is in standby mode.
Allow the replacement IOC module to reboot and qualify the
reference inputs. This provides enough time for the Istate of the
active IOC module to automatically transfer to the replacement IOC
module.
Force the replacement card to the active state.
Replace the other IOC module. The Istate transfers automatically to
that module.
Example
To copy the IMC Istate from the IMC module to the active IOC module, as a prelude
to replacing the IMC module:
