Scsi 320 Raid5


Hi,
I have a rackmount server that i have installed a Ultra 320 Scsi card and
7 120 GB Scsi Drives. I also have a 160 GB IDE Hard Drive which i have installed
red hat 9.0 Kernal 2.4.20-31bigmem.

then i boot up and go into the scsi config (ctrl-a) and set up raid5.

however i still don't see the scsi drives in linux.

so my question is what do i need to install to get the scsi drive array installed?

thanks.

If the drives aren't showing up then chances are the driver for the scsi card isn't loaded....do you know the make and model of the scsi card?

Yes, the Scsi Card is an Adaptec 2230SLP.
I am using Red Hat 9.0

I have installed the Module RPM that came with the Adaptec card.
and now i can see this when i do 'fdisk -l'

[root@bundy root]#fdisk -l


Disk /dev/sda: 733.9 GB, 733903585280 bytes
255 heads, 63 sectors/track, 89225 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sda doesn't contain a valid partition table

Disk /dev/hda: 122.9 GB, 122942324736 bytes
255 heads, 63 sectors/track, 14946 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 14692 117909067+ 83 Linux
/dev/hda3 14693 14946 2040255 82 Linux swap


So now my question is this.
i can't mount this cause it does not have a partition, so how do i go about formatting this array?

****UPDATE******

so do i have to put a file system on these raid array?



thanks..

You need to use the 'fdisk' command to create the partitions, for example:

fdisk /dev/sda

Type n to create the new partition.

Select Primary

set up the partition size...accep the default start cylinder size

next enter the size you wish to make the partition

type p to review the partition table

if everything is to your liking type w to write the changes and exit fdisk


Reboot the system so the partition table is re-read.

Then create the filesystem, for example....to create an ext 3 filesystem:

mke2fs -j /dev/sda1

Once the filesystem is created you need to mount it.

Create a mount point....

mkdir /storage (or whatever)

then mount the new disk:

mount /dev/sda1 /storage

Copy some files to the new mount point to verify it's working.

If you want the new disk to come up on every reboot you need to make a label and add an entry to /etc/fstab:

1) run the following command: umount /storage

2) then run: e2label /dev/sda1 /storage

3) open /etc/fstab in your preferred text editor and add the following line:

LABEL=/storage /storage ext3 defaults 1 2

Save /etc/fstab

mount the new filesystem again by running:

mount /storage
