Warning 4020: A restart of both this and the other controller is required before
all the parameters modified will take effect
Explanation: This warning results from a SET THIS_CONTROLLER or a
SET OTHER_CONTROLLER command. Some controller parameters require
a restart of both controllers before they can take effect. If any of those
parameters are changed, this warning is displayed. Restart both controllers
and retry the command.
Warning 6000: Communication failure with the other controller while taking
controllers out of dual-redundant mode. Issue a SET NOFAILOVER command
on the other controller
Explanation: This warning results from a SET NOFAILOVER command.
This controller was unable to communicate with the other controller to notify
it that it is no longer in dual-redundant mode. Typically, this occurs when the
other controller has already been removed prior to the SET NOFAILOVER
command.
Enter a SET NOFAILOVER command on the other controller as soon as
possible.
Warning 6010: Licensing different between the two controllers
Explanation: If the licensing is not identical on both controllers in a
dual-redundant configuration, the above warning is displayed.
You should check the licensing on both controllers and make sure they are
identical.
Warning 6020: Bad write cache or battery on <controller or controllers> controller
Explanation: <Controller or Controllers> can be THIS_CONTROLLER,
OTHER_CONTROLLER, or both controllers. Your write-back cache module
or its batteries are bad.
Warning 7000: Data written successfully before clearing unwriteable data error
Explanation: As a result of a CLEAR UNWRITEABLE_DATA, if the last-
ditch attempt to write data before clearing the error was successful, the above
warning is displayed.
Note
This means that no customer data was lost, so this warning is actually
good.
Warning 7010: Unable to clear LOST_DATA on other controller
Explanation: When trying to clear LOST_DATA on the other controller, a
communication error occurred.
Retry the command. If the failure persists, contact Digital Multivendor
Customer Services.
