[CentOS] way to replace DELL PERC 6/E card???

[Brian Mathis]

OK, good point and I apologize for seeming rough, though the phrase
"flying blind" is not an really an insult.  Your post sounded a bit
like someone who hasn't dealt with servers much.  The typical answers
for something like this are "read the manuals", and "call support to
get a replacement if you have bad hardware".

As you have over 100 Dell servers there's a high likelihood that you
got a few bad ones, so I would just replace it and move on.  There's
really not much else to do.
