megamon question

[Marcelo Barbudas]

Hi

In the last three days megamon has been sending this kind of emails
about every 10 hours.

[11/25/2007 (00:46:32)]:
         Adapter 0 Logical Drive 0  is DEGRADED.
[11/25/2007 (00:46:32)]:
         Adapter 0 Channel 0 Target 3:
         Physical Drive[        ST380013AS      3.18] is Changed to REBUILD.

[11/25/2007 (01:47:31)]:
         Adapter 0 Logical Drive 0  is OPTIMAL.
[11/25/2007 (01:47:31)]:
         Adapter 0 Channel 0 Target 3:
         Physical Drive[        ST380013AS      3.18] is Changed to ONLINE.

Should I take measures to replace that drive? Could it be a controller 
problem?
