EVA5000: Improper Protocol Error

[Learn_1]

Hi All,
I am noticing the following error in the command view controller event log.EVA5000 is in 2C12D configuration.
"""A physical disk drive is using an improper protocol to attempt communication with an Drive Enclosure Environmental Monitoring Unit.
Corrective action code: 9c"""

and

"""The retry count for a task assigned to a Drive Enclosure Environmental Monitoring Unit has been exhausted.
Corrective action code: 00 """"""

I think that the disk might be about to fail or is there anything else we need to check.
