Re: Marvell SATA status

Hoi Jeff,

The Marvell chip isn't listed on that page unless my eye sight is 
deterioting :-)

The BIOS identifies it as an Adaptec HostRAID 6041 controller (?), 
allows for setting up the arrays etc, however, 'lspci -vv' identifies it 
as a Marvell Technology  MV88SX6041 RAID controller.

It could indeed be software RAID by controller, but as far as the OS is 
concerned the controller presents the array to the OS as a single disc...

Will have a look there too, thanks.

The current driver doesn't work:

sys1:~# dd if=/dev/zero of=/dev/sdb bs=1 count=1
1+0 records in
1+0 records out
1 bytes transferred in 61.346053 seconds (0 bytes/sec)
sys1:~#

So it does recognise the drive but nothing else happens.

I certainly won't be able to complete the driver by myself... so if 
there's little interest in it my only option would be to use the 3ware 
controller...

Thanks for your help,

Jan
