2137 Communication
timeout
Warning /
Non-critical
Cause: The controller is unable to
communicate with an enclosure. There are
several reasons why communcation may be
lost. For example, there may be a bad or loose
cable. An unusual amount of I/O may also
interrupt communication with the enclosure.
In addition, communication loss may be
caused by software, hardware, or firmware
problems, bad or failed power supplies, and
enclosure shutdown.
When viewed in the Alert Log, the
description for this event displays several
variables. These variables are: Controller and
enclosure names, type of communication
problem, return code, and SCSI status.
Action: Check for problems with the cables.
See the online help for more information on
checking the cables. You should also check to
see if the enclosure has degraded or failed
components. To do so, select the enclosure
object in the tree view and click the Health
subtab. The Health subtab displays the status
of the enclosure components. Verify that the
controller has supported driver and firmware
versions installed and that the EMMs are
each running the same version of
supported firmware.
