2137 Communication
timeout
Warning /
Non-critical
Cause: The controller is unable to communicate
with an enclosure. There are several reasons
why communication 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.
