Hello, we have this new box - TS100 6432 17U - and raid 10 is configured with 4  X 500GB physical disks to give us a 1TB virtual drive. Recently the following log entries have started to show up in the system events.

- The driver has detected en error on device \Device\RaidPort0

Then at some point all hell's break lose and the array becomes in rebuild mode (degraded). We also see alot of suspicious log entries in the MegaRAID Storage Manager (MSM) like:

- Link lost on SAS port: 0 PHY = 0

- Link lost on SAS port: 2 PHY = 2

- Link lost on SAS port: 3 PHY = 3

- Controller ID: 0 PD Removed 0:1

....

- Controller ID: 0 PD Inserted 0:1

...

So I kinda think that I should change DISK 0 because I also receive alot, and I mean alot, of these:

Unrecoverable medium error during rebuild: PD 0 Location...

Any Idea besides this?

After changing physical disk 0, I still get error:

The driver has detected en error on device \Device\RaidPort0

Everyone once in awhile. Any help is much appreciated.

welcome to the forum!

you'd be better off calling lenovo support on this one.   if you do have a bad drive on port 0, they'll be able to send you a new one right away.   until then, you'll be stuck with a degraded array -- which i know from prior experience can be painfully slow.   if it's not a bad drive then they'll be able to diagnose it.   trying to solve something like this on a forum isn't easy.

good luck and please post back with your results.

Yep the disc on P0 was the problem which also caused the server to be very slow (at least it was servicing clients).

Thank you for the reply!
