Knowledge Article: ID B0EA0F901: A communication failure has occurred on the XML TCP command/response port for I/O Module %d.

Description

The advanced management module is unable to communicate with the specified SAS I/O module. The SAS I/O module might be functioning normally, but the advanced management module will not be able to generate any additional events for the SAS I/O module.

Causes

The advanced management module is unable to communicate with the specified SAS I/O module. The SAS I/O module might be functioning normally, but the advanced management module will not be able to generate any additional events for the SAS I/O module.

Implications

The SAS I/O module might still be working, but there is a problem in the communications between the advanced management module and the SAS I/O module

Resolutions

Perform these steps:

  1. Wait a few minutes to see if a recovery event is generated (especially if the firmware for the SAS I/O module has just been updated).

  2. Access the Web interface for the SAS I/O module to verify that it is working. If so, you might be able to wait for a scheduled outage to resolve the problem.

  3. Reseat the advanced management module.

  4. Reset the SAS I/O module through the advanced management module interface.

    Note: When you reset the SAS I/O module, all connections to that I/O module will be broken, which may result in loss of data.
