I'm a bit of a n00b when it comes to Linux, but something I'd been wondering about for a while was CFLAGS settings, and whether I could make anything run better. After recompiling BM and re-running it, it made little or no difference (marginally slower, but within margin of error). Not to daunted I wondered about recompiling the 2.4.26 kernel, just changing -O2 up to -O3 in Makefile. Recompiled and setup, and was rather surprised at the speed increase!

I have successfully installed RedHat 8.0 onto a Dell PowerEdge SC1425 today. This server has two SATA hard drives, and an IDE DVD-ROM drive.
Using the following kernel parameters, i successfully installed across both hard drives from CD:

Does anybody no how to get around the fact that the Red Hat installation does not see the SCSI hard drives. It lets you manually pick the proper device, but still fails saying no drive detected (or something to that effect). I was going to install windows 2003 Server and use VMware...but again,...

Hello all,
I'am experiencing weird relyability problems with a SCO 6.0 Openserver server that runs on a Dell Poweredge 1800 equipped with a PERC DC4 raid controller and 4 36 GB 15 K rpm hot swappable scsi harddisks.
It runs a RAID 10 configuration.
It uses the mega hba, Revision 8.03a Release... (1 Reply)
Hi,

I was asked to get a Dell PowerEdge 2600 server, out of warranty, running SCO 3.2v5.06 to perform a full backup. I spent hours researching and preparing a strategy only to fail on-site.
The only device names in /dev for a tape drive were
/dev/xStp0
/dev/xcdt0

MFI(4) BSD Kernel Interfaces Manual MFI(4)NAME
mfi -- LSI Logic & Dell MegaRAID SAS RAID controller
SYNOPSIS
mfi* at pci? dev ? function ?
DESCRIPTION
The mfi driver provides support for the MegaRAID SAS family of RAID controllers, including:
- Dell PERC 5/e, PERC 5/i, PERC 6/e, PERC 6/i
- Intel RAID Controller SRCSAS18E, SRCSAS144E
- LSI Logic MegaRAID SAS 8208ELP, MegaRAID SAS 8208XLP, MegaRAID SAS 8300XLP, MegaRAID SAS 8308ELP, MegaRAID SAS 8344ELP, MegaRAID
SAS 8408E, MegaRAID SAS 8480E, MegaRAID SAS 8708ELP, MegaRAID SAS 8888ELP, MegaRAID SAS 8880EM2, MegaRAID SAS 9260-8i
- IBM ServeRAID M1015, ServeRAID M5014
These controllers support RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 and RAID 60 using either SAS or SATA II drives.
Although the controllers are actual RAID controllers, the driver makes them look just like SCSI controllers. All RAID configuration is done
through the controllers' BIOSes.
mfi supports monitoring of the logical disks in the controller through the bioctl(8) and envstat(8) commands.
EVENTS
The mfi driver is able to send events to powerd(8) if a logical drive in the controller is not online. The state-changed event will be sent
to the /etc/powerd/scripts/sensor_drive script when such condition happens.
SEE ALSO intro(4), pci(4), scsi(4), sd(4), bioctl(8), envstat(8), powerd(8)HISTORY
The mfi driver first appeared in NetBSD 4.0.
