cf.cdo EMS events occur when ONTAP encounters issues associated with disk operations over the High Availability (HA) interconnect.
cf.cdo.badMsg
- Severity
-
ERROR
- Description
-
This event is issued when the filer receives a disk operation message over the High Availability (HA) interconnect that it does not recognize. This is likely due to a change in the message protocol that the down-revision partner does not recognize. Fix this problem by upgrading the partner to a compatible version of Data ONTAP®. This message is not emitted for every message received to avoid spamming the console.
- Corrective Action
-
Upgrade both nodes to the same release.
- Syslog Message
-
unknown message %d received from partner (%d unknown messages since boot).
- Parameters
-
msg (INT): Message which was not known.
count (INT): Number of unknown messages.
cf.cdo.reportOp
- Severity
-
NOTICE
- Description
-
This event is issued when the filer bypasses or unbypasses a disk after being requested to do so by its partner. The bypassing of a drive on a particular port may only be done by the host which is attached to that port; the High Availability (HA) software ensures that both ports of the drive are bypassed by communicating bypass requests to the partner.
- Corrective Action
-
(None).
- Syslog Message
-
%s disk %s on behalf of the partner.
- Parameters
-
op (STRING): Operation description
driveName (STRING): Drive name
