Number Severity Description/Recommended actions
Recommended actions:
● Update the firmware on one or both systems so they are running the same version.
● Check your network or fabric for abnormally high congestion or connectivity issues.
436 Warning Firmware in the remote system is incompatible with firmware in the local system so they cannot
communicate with each other to perform replication operations.
Recommended actions:
● Update the firmware on one or both systems so they are running the same version.
437 Info. A request by a user to change the primary volume of a replication set was started.
Recommended actions:
● No action is required.
438 Info. A request by a user to change the primary volume of a replication set completed successfully.
Recommended actions:
● No action is required.
439 Error A request to change a primary volume failed.
This can occur for several reasons, such as:
● The volume is not in the replication set.
● Configuration tag or configuration data not found.
● The retry limit has been reached.
Recommended actions:
● Verify that the specified volume is part of the replication set.
● Verify that there are no network issues preventing communication between the local and
remote storage systems.
440 Warning A replication is being retried due to an error in the secondary volume.
This can occur for several reasons, such as:
● The cache request was aborted.
● The cache detected that the source or target volume is offline.
● The cache detected a media error.
● The snap pool is full.
● The communication link is busy or experienced an error.
● The snapshot being used for the replication is invalid.
● There was a problem establishing proxy communication.
●
The replication is being automatically retried according to policies in place. If the issue is
resolved before retries are exhausted, the replication will continue on its own. Otherwise, it
will go into a suspended state unless the policy is set up to retry forever.
Recommended actions:
● If any of the above problems exist, resolve them.
441 Error A request to add a secondary volume failed. User intervention is needed to remove the volume
from the set.
Recommended actions:
● Remove the indicated secondary volume from the replication set.
442 Warning Power-On Self Test (POST) diagnostics detected a hardware error in a UART chip.
Recommended actions:
● Replace the controller module that logged this event.
