Hello ,

I've some problems with a Net RAID 2M cards installation with linux under WOODY 3.0 DEBIAN
We have some hangs at different times when installing os
We are sure that it comes from 2M cards with I/O errors
We're trying an update firmware which is actually G.01.03 without any succes .
I'hope that it is a slightly errors , if any body have some ideas on it , thanks



I would say hello to my old chaps at HP France , with a particuliar mind to my friend KODJO ;-) !

Hi,

I am not familiar which version of megaraid is in 3.0 Debian.
NetRAID-2M needs at least 1.08 of megaraid. Otherwise, system can not detect your 2M.
Latest firmware for 2M can be download from http://h20004.www2.hp.com/keeper_rnotes/bsdmatrix/matrix51930.html
According to this page, the rev is H.02.01.
This version of firmware fix the nasty "64bit mode filesystem corruption".
But one thing you may want to check about "stripe size" when you create the Logical Unit.
Default stripe size is 64kb.
But if you set less than 64kb stripe size, you will see I/O error. So my advice is, check LU's stripe size.
If it is less than 64k, what you need is recreate the LU, which mean clear the LU then recreate.

Good luck
