Linux-PowerEdge Digest, Vol 43, Issue 18

Your system is fine, the degraded state is caused by the driver being
outdated:

Driver Version                    : 00.00.03.01
Minimum Required Driver Version   : 00.00.03.13

"The Status, State, and Rate lines are what worry me.  They just stay at
this 
level.  The rebuild does not ever complete."

There is no rebuild going on. The rate entries refer to the amount of
controller CPU power, is allocated to the specific tasks.

I'm having a rather odd issue with my PERC 5/i RAID controller that I
can't 
figure out.  I believe this occurred right after upgrading the firmware
to 
5.2.1-0067 (from 5.1.1-0040), but to be honest I'm not 100% certain.

To summarize as much as possible, shortly after performing the upgrade I

noticed that I could no longer query my drive/controller information
through 
the 'omreport storage' command.  I could still run 'omreport system'
just 
fine, but any attempts to query the storage components gave me an error 
along the lines of "controller not found" (sorry, can't remember the
exact 
message).

A few reboots later, for whatever reason, this worked itself out.  I can
now 
query both the controller and drives through pdisk and vdisk.  However,
when 
I now do this I get the following warning from the controller:

# omreport storage controller

The Status, State, and Rate lines are what worry me.  They just stay at
this 
level.  The rebuild does not ever complete.

Compounding the 'weirdness' is that the actual disks all report that
they 
are fine (abbreviated for brevity):

# omreport storage pdisk controller=0 | grep '^ID\|Status\|State'
ID                        : 0:0:0
Status                    : Ok
State                     : Online
ID                        : 0:0:1
Status                    : Ok
State                     : Online
ID                        : 0:0:2
Status                    : Ok
State                     : Online
ID                        : 0:0:3
Status                    : Ok
State                     : Online

# omreport storage vdisk controller=0 | grep '^ID\|Status\|State'
ID                  : 0
Status              : Ok
State               : Ready

So, all of my disks and volumes appear to be fine, but the controller is

reporting that it's in a perpetual degraded state.  What's the deal?
How 
can I fix this?

Since my disks are reporting that they're good, and my system is running
as 
expected, I'm thinking the controller issue is a false positive or 
something, but I'm rather nervous about potentially losing my data and
just 
don't want to take that chance.  Would definitely appreciate any
assistance 
here.

Thanks!
