Description
The controller has detected an invalid
disk drive dual-port connection. This
connection does not have the benefit
of fault tolerance. Failure of the disk
drive port would cause loss of access
to the drive.
Errors detected on the specified disk
channel have caused the storage
system to mark the channel as
degraded.
The Management Controller has
powered up or restarted.
The Management Controller is about
to restart.
The IP address has been changed in
the Management Controller.
The Management Controller (MC)
has not sent a command to the
Storage Controller (SC) for an
interval that exceeds the MC
communication timeout, and may
have failed. This is sometimes
referred to as a "LAN not talking"
error. This event is logged as
informational when the SC has not
received communication from the MC
for 160 seconds. If communication is
restored in less than 15 minutes,
event 153 is logged. If the SC has not
received communication from the MC
for 15 minutes, this event is logged as
a warning, the SC restarts the MC,
and event 156 is logged.
The Management Controller has re-
established communication with the
Storage Controller.
Recommended Action
The single disk drive port should
be connected to one controller only.
Determine the source of the errors
on the specified disk channel and
replace the faulty hardware.
When the problem is fixed, event
189 is logged.
If this occurs repeatedly and user
interfaces are not working
normally, a hardware failure is
indicated. Replace the controller
module that is logging this event.
