Along with the above it might be good to have an idea of how the hard disk is arranged. Accomplished with
. Also would help to know what accounting program or how it is set up as some go into the /usr or /usr2 areas with all the programs and data there and transferring to a new machine a matter of copying that across.
Help, if possible.

Hi,
I have a server that I am adding a RAID that we purchased to. The server works fine. It is running Fedora 7 and is a Dell Precision 690.
When the RAID is attached, it boots up and says the following:
Controller Bus #00, Device#1F, Function#02: 00 Ports
No device found

I am planning on building a fedora box with raid controller (database server).
Is anybody done that ? also what kind of software do you need to backup and recover data. (1 Reply)
I need to put together a RAID1 file server for use by Windoze systems. I've built zillions of windows systems from components. I was a HPUX SE for a long time at HP, but have been out of the game for years.

Hi All
I have a Sun T2000 server. Couple of years ago I had configured and mirrored the boot drive with an other drive using hardware RAID 1 using raidctl command.
Following is the hardware RAID output.

I just built a home computer with 3TB hard drives I wanted to set up in a RAID 5 and load Ubuntu server onto it.
The first thing I did was set up the drives in a RAID 5 using just the motherboard chipset software to do it, so a 'hardware' RAID basically.
I installed Windows first to see if... (2 Replies)
First time poster and a very new Unix user, so I'll just pre-apologize for stupid questions now.
Does anybody know of a good RAID 1 hard drive backup that is Unix friendly? I want to avoid any hardcore programming. Can you recommend both NAS and non-NAS options? I need to do nightly backups... (31 Replies)
We have a 3ware RAID server at work, and as the appointed systems administrator (by virtue of being the one with the most knowledge) I've taken on the job of maintaining it. I've installed smartmontools on it to keep an eye on the drives and run scans every day, and looking at the data from the... (0 Replies)

WREN(3) Library Functions Manual WREN(3)NAME
wren, ata - hard disk interface
SYNOPSIS
bind #H[drive] /dev
bind #w[target[.lun]] /dev
/dev/hd0disk
/dev/hd0partition
/dev/sd0disk
/dev/sd0partition
...
DESCRIPTION
The hard disk interfaces (wren, #w, is a SCSI disk; ata, #H, is an IDE or ATA disk) serve a one-level directory giving access to the hard
disk partitions. The parameter to attach defines the numerical SCSI target and logical unit number or the IDE drive number to access.
Both default to zero.
Each partition name is prefixed by hd and the numeric drive identifier. The partition always exists and covers the entire disk. The size
of each partition as reported by stat(2) is the number of bytes in the partition, so the size of is the size of the entire disk.
The partition also always exists; it is the last block on the disk for SCSI, second to last for IDE. If it contains valid partition data,
those partitions will be visible as well. Every time the device is bound, the partitions are updated to reflect any changes in the parti-
tion file.
The format of the partition file is the string
plan9 partitions
on a line, followed by partition specifications, one per line, consisting of a name and textual strings for the block start and limit for
each partition on the disk.
The program prep(8) writes the partition table for the disk; its use is preferred to writing it by hand.
