7-7
3: ZX25-EVT-IOBUS-ERROR
This event can be caused by a controller generating a continuous I/O power-on
interrupt. In this case, the application that is trying to communicate with the line
receives an error code (usually #231, I/O power on) in response to its I/O request.
This event can occur on a NonStop VLX system during a transfer between $OSP
(ldev has the value 3) and the RMI. In this case, the operation is simply retried.
Recovery. Appropriate recovery action depends on the file-system error that occurred.
For information on file-system errors and how to recover from them, see the Guardian
Procedure Errors and Messages Manual.
For the NonStop VLX and the OSP, this event message is an informative message
only; no corrective action is needed.
