Proliant Smart Array scsi internal disk configuration

Davide Depaoli_3 — Thu, 13 Jul 2006 06:25:12 GMT

Hello,
I'm not a linux expert. I'm working on a following environment:

Linux Red Hat Enterprise 3.0
Proliant DL380
MSA1000 storage array

with boot from san.

Now my customer wants to use the internal server hard disk as a data disk (not a boot disk) but only as filesystem.

Linux see the internal Smart Array controller, but not the hard disk.

Can anyone helps me to do this (if possible) ?

thanks in advance
kind regards
Davide

You should start from creating "disks" and partitioning your internal RAID. You can do this or during your DL380 boot in SmartArray BIOS, or using this utility:

HP Array Configuration Utility for Linux
http://h18000.www1.hp.com/support/files/server/us/download/23364.html

Can you send us output of

sfdisk -l

or

fdisk -l /dev/cciss/c0d0

Hi,
I've created disk in SA Bios and it is seen in ACU, but in Linux I only see the MSA1000 LUNs, and not the internal hdd.

With Hardware Browser I see the Smart Array controller.

I'm working in a test lab and have started a new Red Hat installation.
With Disk Druid the new disk is available and configurable (/dev/cciss/c0d0p1).

In a already running O.S. is there any command to discover this disk (kudzu doesn't discovered the hdd) ?

thanks Davide

Please post here the contents of "fdisk -l". Chances are that you have either not set up an array with the SA64xx, or that the array hasn't been formatted yet with mkfs.

Unfortunately I'm not more on that lab, and I'm not be able to work on that system.
But my big question is:

if disk-druid see this hdd, in a running linux is there any cmd or GUI utility like disk-druid able to make the hdd available ?

If the OS can see the cciss array with fdisk -l, then you will need use fdisk to make a partition (which seems to be done, if you have a p0 assigned to it), then you need to use mkfs to format the partion with an ext3 filesystem, then you need to use "mount" to mount the partition to a mount point.

I would recommend reading chapter 9 of "Unix System Administration Handbook" by Nemeth, et al. A similar chapter is probably somewhere in Nemeth. et al's "Linux System Administration Handbook". Either book is a must for *nix sys admins.
