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!
hi, i am trying to install solaris 10 (on 4 cd's downloaded from the sun website) on my dell poweredge 2800 server. 2 xeon processors, 2GB of RAM and 2 NICS, 73 GB SCSI (maxtor ultra320, 3.5 series), i can give more details on request...

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,...

I have 2 Dell Poweredge 1950 servers running . I have been having intermittent performance issues with the NIC cards on one of them. The two servers are identical and are running the same operating system. The server that has the issue is on the DMZ on a a static IP and is hosting a website. ... (0 Replies)
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 have a C++ program to access /dev/mem and retrieve details like Vendor, Manufacturer details of the motherboard. This works fine on all the machines except for on Dell Poweredge 2850,1950... machines.
I receive a 'EFAULT' when I try to access /dev/mem on these servers.
I suspect some... (1 Reply)
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

ARCMSR(4) BSD Kernel Interfaces Manual ARCMSR(4)NAME
arcmsr -- Areca Technology Corporation SATA/SAS RAID controller
SYNOPSIS
arcmsr* at pci? dev ? function ?
DESCRIPTION
The arcmsr driver provides support for the PCI-X and PCI Express RAID controllers from Areca Technology Corporation:
- ARC-1110 PCI-X 4 Port SATA RAID Controller
- ARC-1110ML PCI-X 4 Port SATA RAID Controller
- ARC-1120 PCI-X 8 Port SATA RAID Controller
- ARC-1120ML PCI-X 8 Port SATA RAID Controller
- ARC-1130 PCI-X 12 Port SATA RAID Controller
- ARC-1130ML PCI-X 12 Port SATA RAID Controller
- ARC-1160 PCI-X 16 Port SATA RAID Controller
- ARC-1160ML PCI-X 16 Port SATA RAID Controller
- ARC-1170 PCI-X 24 Port SATA RAID Controller
- ARC-1200 Rev A PCI Express 2 Port SATA RAID Controller
- ARC-1202 PCI Express 2 Port SATA RAID Controller
- ARC-1210 PCI Express 4 Port SATA RAID Controller
- ARC-1220 PCI Express 8 Port SATA RAID Controller
- ARC-1230 PCI Express 12 Port SATA RAID Controller
- ARC-1230ML PCI Express 12 Port SATA RAID Controller
- ARC-1231ML PCI Express 12 Port SATA RAID Controller

- ARC-1280 PCI Express 24 Port SATA RAID Controller
- ARC-1280ML PCI Express 24 Port SATA RAID Controller
- ARC-1680 PCI Express 8 Port SAS RAID Controller
- ARC-1680LP PCI Express 8 Port SAS RAID Controller
- ARC-1680i PCI Express 8 Port SAS RAID Controller
- ARC-1680x PCI Express 8 Port SAS RAID Controller
- ARC-1681 PCI-X 8 Port SAS RAID Controller
These controllers support RAID levels 0, 1, 1E, 3, 5, 6, and JBOD using either SAS or SATA II drives.
arcmsr supports management and monitoring of the controller through the bioctl(8) and envstat(8) commands.
Please note, however, that to use some features that require special privileges, such as creating/removing hot-spares, pass-through disks or
RAID volumes will require to have the password disabled in the firmware; otherwise a Permission denied error will be reported by bioctl(8).
When a RAID 1 or 1+0 volume is created, either through the bioctl(8) command or controller's firmware, the volume won't be accessible until
the initialization is done. A way to get access to the sd(4) device that corresponds to that volume without rebooting, is to issue the fol-
lowing command (once the initialization is finished):
$ scsictl scsibus0 scan any any
The arcmsr driver will also report to the kernel log buffer any error that might appear when handling firmware commands, such as used by the
bioctl(8) command.
EVENTS
The arcmsr driver is able to send events to powerd(8) if a volume or any drive connected to the volume is not online. The state-changed
event will be sent to the /etc/powerd/scripts/sensor_drive script when such condition happens.
