I have a RAID 1+0 consisting of 4x 146GB SAS disks on a Smart Array E200i.

One disk reports an error in event log:

The Physical drive at Port 1I : Box 1 : Bay 2 is reporting S.M.A.R.T. errors.

Can I replace the failed disk when Windows Server 2003 is runnig?

If you have a spare bay you might consider adding a hot spare. You should also add alerting because the event log is not the first place you should learn about these issues. Check the controller manual, as many controllers are capable of sending alerts directly. – John Gardeniers Oct 19 '12 at 10:13

Depends on your RAID configuration.

If you have simple concat or simple stripe you will break volume.

Any mirrored configuration should be OK if just one disk fails.

RAID 1+0 (mirrored stripe) is also OK.

Only if your disks are hot-pluggable. Check their specifications, if I remember correctly there are some not hot plug sas disks at HP.
