Hi,

I noticed strange events in event log on my MD3620F disk array (which is almost
2 years old):

==============================================

It is repeated twice for each RCM ...

For me disabling cache usage on such disk array is a serious issue.
But looks like NOT: Priority: Informational, Event needs attention: false

And just few days earlier battery is claimed good:

===================

Could it be anyhow related to one VD resizing (enlarge)????

And why there is no event like:  RAID Controller Module cache ENEBLED ???

Should I worry about batteries or whole disk array or its performance ??

Kind regards,

Grzegorz
