SCSI, RAID controllers, Linux. . .

[Norvell Spearman]

The company I work for has a server which originally was going to run
SCO OpenServer 5, but may end up running Linux instead. The server has
a DPT PCI SCSI PM2044U controller, with a DPT RC4040 RAID controller
attached to it. I found on RedHat's website that the DPT PM2044 is
supported (don't know if the `U' on the end matters), but couldn't find
anything for or against the RAID controller---I've heard that ``not
listed = not supported.''

We already have SCO installed on the server (on one huge partition) and
so we started installing RedHat Linux 5.1 to see how it goes. We got to
fdisk and it *seemed* to recognize the RAID array: it showed up as
/dev/sda4, with GNU HURD as the file system type. This is where we
stopped.

So the main question is this: Does Linux actually recognize the RAID
array (what is a GNU HURD fs?), and are there any Linux utilities
available for reporting on the status of/repairing a RAID array?

Many thanks for any help with this. . .

The U usualy means ultra, that should not make a differnce for you.

check out these sites:

It seems like the raid device is an invisable (acts a single disk)
controler, and should work fine, you should be able to find info about
how to control it on these sites.

I don't see the 4040, but it looks like the DPT HW is (was?)
conforming to a kind of standard, so new HW may work with
old SW. ???
