what /dev/device is associated with an Areca RAID card?


I'm running a computer with Windows 7 as a main OS. I've got Debian 6.0.3 installed on a separate partition since I prefer working with Debian myself. Anyway there is a big RAID Array running from an Areca card, partitioned as NTFS.

How can I find that out which device is associated with the raid array? Currently I'm running:

Code:
grep --ignore-case areca /proc/
(only feedback is not sufficient memory in /proc/kcore)

I already tried

Code:
fdisk -l
but it doesn't show up there

Hi,

What do you see with 'lspci -vv'?

There's a kernel module 'arcmsr' that supports most of the Areca RAID cards.
See if this is loaded with
Code:
# lsmod | grep arcmsr
If not, just load it with
Code:
# modprobe arcmsr

Well it does show up in the lspci w/o -vv so it's recognized. If you still need the output I'll post it later on (the ol' folks are working on the pc now)

I can't seem to find a block device that I can use to mount. On the top of my head I did:

Code:
user@box:~$ ls /sys/block
loop0  loop1  loop2  loop3  loop4  loop5  loop6  loop7  sda  sdb sdc sdd sde sdf
user@obx:~$
If I try to 'cat' the last 4 devices I got an error and no output so that's not the 4 disks attached to the controller. With the sda and sdb (being 2 physical present discs) I got the expected "messy" output.

lspci just shows whatever is plugged in. It doesn't mean it's detected and working. With the -vv option you might see if a kernel module has been loaded to support it.

Just one of the commands that can help identify things to aid in troubleshooting. Sometimes errant loads or misconfiguration can be identified.

Hi,

It could be that you need fuse-3g 'driver' for mounting NTFS volume.
Like mounting ntfs in debian/
or maybe here (more explanation)

good luck

Spot on Lithos!!!

I downloaded the latest stable fuse (2.8.5 I thought it was) and did ./configure && make && make install && reboot

I've got a new device /dev/sda and I could mount it!!

Can someone explain why the device didn't show up at first?
