[Linux-PowerEdge] OMSA says failed drive but LED is solid green and LCD displays no error

no, it's fine this way, because both drives are not failed or yet for
drive 1. in OMSA there is a column 'failure predicted' (maybe you'll
have to switch to 'full view') it should say 'yes' for drive 1. 
drive 0 is fine and drive 1 should be replaced soon, because it's going
to fail.
