136 Warning Errors detected on the specified disk channel
have caused the storage system to mark the
channel as degraded.
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.
139 Informational The MC has powered up or restarted.
140 Informational The MC is about to restart.
141 Informational The IP address has been changed in the MC.
152 Informational
or warning
The MC has not sent a command to the 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.
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.
153 Informational The MC has re-established communication
with the SC.
154 Informational New software has been loaded on the MC.
155 Informational New loader software has been loaded on
the MC.
156 Informational The MC has been restarted from the SC.
157 Critical A failure occurred when trying to write to the
SC flash chip.
Replace the controller module.
160 Warning The EMP enclosures are not configured
correctly. All enclosure EMPs on that channel
are disabled.
Check that EMP enclosures are configured
correctly and issue a rescan.
161 Informational One or more enclosures do not have a valid
path to an EMP. All enclosure EMPs are
disabled.
162 Warning The host WWNs (node and port) previously
presented by this controller module in this
system are unknown. This event has two
possible causes:
• One or both controller modules have
been replaced or moved while the system
was powered off.
• One or both controller modules have had
their flash configuration cleared (this is
where the previously used WWNs are
stored).
The controller module recovers from this
situation by generating a WWN based on
its own serial number.
Verify the WWN information for this
controller module on all hosts that access it.
