Hardware :: Automatically Configuring Logical Drives For HP Smart Array P400 Controller
Jan 6, 2011
Is it possible to automate the configuration of a servers raid drives (my system has a HP Smart Array P400 controller) or does that have to be done manually? Right now, when I get a rack of new servers, I have to go through each one and use the ORCA tool to setup the logical drives. I'm hoping there is some way to automate that. And forgive the lame question, but I am assuming you have to configure the logical drives before you can install the OS?

I've just begun with a fresh USB install of Ubuntu 11.04, and have run into the seemingly standard wireless network issue with the Broadcom 4311. I've read countless posts on this forum, and have installed the STA driver "proprietary..." through the GUI driver installer.
The usual symptoms seem to persist; I can connect to the network using my wired connection, but when I unplug no wireless network connections kick in, or show up, or seem to be responsive anywhere..Also, I should note that I've read the forum post HERE but without much further understanding or resolution.

Trying to install RHEL5-AS 64bit onto HP DL320 G6, with RAID being a mirrored array on the Smart Array B110i SATA controller. The RAID is configured in the BIOS and seems fine.
When I install RedHat, I have to use 'linux dd' to use the HP provided driver (http://h20000.www2.hp.com/bizsupport...5&mode=4&idx=0) and that works fine during the installer, the GUI during the install sees the RAID just fine, it sees one volume, calling it the HP Volume. However, when the system boots after the install, the RAID is gone, and it's now seeing two drives, /sda and /sdb:

I've looked high and low but I haven't been able to find any example of what I'm currently experiencing with my hard disks.First off, I'm running CentOS as a Samba file server, on a Soltek SL-K8TPro-939 and AMD 64 3200+ (all the rage of five years ago). Here's my disk setup
Drive #1 (80 GB)
-Boot partition
-LVM partition (this drive holds the root filesystem[code]....
Ok, so I get a notification in my system mail yesterday: The following warning/error was logged by the smartd daemon:
Device: /dev/sda, unable to open device
For details see host's SYSLOG (default: /var/log/messages).You can also use the smartctl utility for further investigation.No additional email messages about this problem will be sent.

I have been using XP pro for a long time and installed Ubuntu 9 2 days ago. Before installing Ubuntu what I did as follows:
1. Deleted all the Partitions using XP installation cd.
2. Created 4 partions like C,D,E,F without formatting any drive. All the 4 partitions have the RAW data.
3. Deleted the partition of C drive and got the unpartitioned space of my hard disk.
4. Installed Ubuntu in this unpartitioned space.
Now the ubuntu is working perfectly, but the issue is I can't access my those 3 (D,E and F)logical drives which are in RAW format. How to format those drives and get access of them. I do not want to install XP again.

i have a fedora 11 server which can't access the ext4 partitions on lvm logical volumes on a raid array during boot-up. the problem manifested itself after a failed preupgrade to fedora 12; however, i think the attempt at upgrading to fc12 might not have anything to do with the problem, since i last rebooted the server over 250 days ago (sometime soon after the last fedora 11 kernel update). prior to the last reboot, i had successfully rebooted many times (usually after kernel updates) without any problems. i'm pretty sure the fc12 upgrade attempt didn't touch any of the existing files, since it hung on the dependency checking of the fc12 packages. when i try to reboot into my existing fedora 11 installation, though, i get the following screen: (click for full size) a description of the server filesystem (partitions may be different sizes now due to the growing of logical volumes):
Code:
- 250GB system drive
250MB/dev/sdh1/bootext3
lvm partition rest of driveVolGroup_System
10240VolGroup_System-LogVol_root/ext4
[code]....
except he's talking about fake raid and dmraid, whereas my raid is linux software raid using mdadm. this machine is a headless server which acts as my home file, mail, and web server. it also runs mythtv with four hd tuners. i connect remotely to the server using nx or vnc to run applications directly on the server. i also run an xp professional desktop in a qemu virtual machine on the server for times when i need to use windows. so needless to say, it's a major inconvenience to have the machine down.

I've recently started having an issue with an mdadm RAID 6 array that been operational for about 2500 hours.
Intermittently during write operations the array stalls, dropping to almost 0 write speed for 10-30 seconds. When this occur one or both of the 2 drives attached to a 2 port Silicon Image si3132 SATA-II controller "locks up" with its activity light locked on. This just started occurring within the last week and didn't seem to coincide with any update that i noticed. The array has just recently passed 12.5% full. The size of the write does not seem to make any difference and it seems completely random. Some times copying a 5 GB dataset results in no slow down other times a torrent downloading to the array at 50kb/sec does cause a slow down and vise versa.
The array consists of 8 WD 1.5TB drives, 6 attached to the ICH9R south bridge, and 2 attached to a si3132 based PCI express card. The array is formatted as a single ext4 partition.
Checking SMART data for all drives shows no errors. Testing read speed with hdparm reports what i would expect (100mb/sec for each drive, ~425mb/sec for the array).
The only thing i did notice is that udma6 is enabled for all the ICH9R drives while only udma5 is enabled for the si3132 drives. Write cache is enabled for all the disks. Attempting to set the si3132 drive to udma6 results in an IO error from hdparm.
The si3132 drive is using the sata_sil24 driver. Nothing of interest appears in the kern or syslog. During this time top shows very high wait time.
The s13132 controller appears to have the original firmware from 2006 loaded, there are some firmware updates available on the Silicon Image website for this controller that now appear to offer separate firmwares for RAID operation (some sort of hybrid controller/software thing the controller supports) and a separate firmware for standard IDE use.
Has anyone had similar issues with this controller? Is a firmware update a reasonable course of action? If so which firmware is best supported by the linux driver?
I know i'm not using its raid features but i've dealt with controllers that needed to be in raid mode for ahci to be active and for linux to work well with them. I'm bit ify at the idea of just trying it and finding out as it could knock 2 disks of my array out of action.

In windows 7, I had 5 partitions on a hard disk: C, D, E, F, G . I installed Scientific Linux 5.0 on C partition and it removed Win 7 . It's graphic mode didn't work, also I couldn't access to the other drives. I replaced it by Fedora 13. I can work graphically Fedora but when I mount the other drives, just D drive is visible! Is there any solution that I could access to the data on other drives? By the way, the following is the output of fdisk -l .
[root@Niki ~]# fdisk -l

I'm installing Ubuntu to be used as an NFS storage server for my VMWare ESX servers. I've got a server that has two 2TB drives in it. The hardware raid controller isn't an option because it only sees up to 1TB of each drive. So, I'm trying to figure out to do this using either LVM or Parted. I don't know much about doing this, and LVM was the first thing I tried but it didn't seem to do much. It looks like it just created a smaller partition to install Ubuntu on. It didn't ask me what I wanted to do with the rest of the drive space. I've messed around with Parted and am not sure what to do, to be honest. I found a few blog posts but most started off assuming that I knew how to get to where they were starting from.
It's just two drives, /dev/sda /dev/sdb

I'm sure many of you here have worked with disk quotas and lvm2 and my problem involves both. Basically what I'm wanting to do is have it so whenever a logical volume gets below a certain constraint (10Gb's) ie. it only has that much left - I want to automatically resize it to add 20 GB's. Obviously this can be done rather easily manually, and with a bit of python hacking it can be done programmatically but since this is for production use I was wondering if there was something a bit more fluid. Since this server is I/O intensive ZFS implemented via FUSE is not an option and neither is the still unstable BtrFS.

I shall start off by saying that I have just jumped from Windows 7 to Ubuntu and am not regretting the decision one bit. I am however stuck with a problem. I have spent a few hours google'ing this and have read some interesting articles (probably way beyond what the problem actually is) but still don't think I have found the answer.I have installed:
Distributor ID: Ubuntu
Description: Ubuntu lucid (development branch)
Release: 10.04
Codename: lucid
I am running the install on an old Dell 8400. My PC has an Intel RAID Controller built into the MB. I have 1 HDD (without RAID) (which is houses my OS install) and then I have 2 1TB drives (These are just NTFS formatted drives with binary files on them nothing more.) in a RAID 1 (Mirroring) Array. The Intel RAID Controller on Boot recognizes the Array as it always has (irrespective of which OS is installed) however, unlike Windows 7 (where I was able to install the Intel RAID controller driver) .Does anyone know of a resolution (which doesn't involve formatting and / or use of some other software RAID solution) - to get this working which my searches have not taken me too?

We have made a fresh installation on DL 580 G 5 Server. The installation Completes successfully. When we reboot the server we find an error message " Logical Drive Disable due to Possible Data Loss. and then non system disk or disk error.
Due to this we have lost all of the data. We can successfully install Windows Server 2008 or 2003 or Redhat Enterprise Linux 5 on this server with no error no issue.we can successfully install Windows Server 2008, 2003 or RedHat Enterprise on RAID 5 or RAID 6 Or RAID 1 or RAID 1+0. we dont face any issue on these windows or linux platforms.We are only facing RAID Controller Issue on CentOS 5

Alright, I have this issue on both SystemRescueCD and Debian Squeeze. I have an ASUS P5Q Turbo board that supports hardware RAID. If I configure an array and then start the Linux installer or boot the rescue CD, I get /dev/sda and /dev/sdb instead of an array. What gives? I need to start installing within the hour so I am desperate for an answer!

I just finished a build of a new GNU/Linux boxen with openSUSE 11.2. I have a MSI Big Bang Xpower X58 motherboard which has two SATA controller chips, one is the standard Intel ICH10R chip for SATA 3.0 Gb/s and one is the Marvell 9128 chip for SATA 6.0 Gb/s. The BIOS recognizes the Western Digital Caviar Black 6.0 Gb/s drive on either SATA controller chips, /however/ I am unable to install (and boot) when the drive is connected to the Marvell controlled ports. As you can guess, I'd like to boot from the faster interface!
1. The BIOS allows me to select the Western Digital drive as a secondary boot device, so I know, at least at the BIOS level, it's there. This is true whether I have the drive connected to the Intel or Marvell ports. (The DVD drive is the primary boot device.)
2. When trying to install openSUSE 11.2 from DVD, the installer says that it can't find any hard drives on my system when I have the drive connected to the Marvell port. The installer finds the drive fine when it is connected to the Intel port.
3. I installed everything with the drive connected to the Intel port. I switched the drive to the Marvell port afterward and the system refuses to boot completely, stalling at some point where it starts to look for other filesystem partitions. This led me to conclude that perhaps the problem is with openSUSE and not hardware weirdness with the system having two separate SATA controllers?

I want to make a RAID5 array with 4 2TB hard drives. One of the drives is full of data so I will need to start with a 3 disks and then once I copy the data from the 4th onto the array, I will then add the 4th drive. This will be my first experience with RAID. I've spent a few hours searching for info but most of what I have found is a bit over my head.

Just got 3 extra drives for my machine.
2x160Gb sata
1x 165Gb sata
How do i create a raid0 array of these drives? On each drive i have got a partition whose size is 160GB and formatted to type fd (Raid Autodetect) i have tried the following:
Code:
mdadm --create /dev/md0 --level=0 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sda1
mkfs.ext4 /dev/md0
mount /dev/md0 /media/raid
but for some reason it doesnt work.

I got my system up and running with the Grub installed on my primary hard drive. I have not installed 2 additional drives. I would like to combine the 2 additional drives into a RAID 1 array. I can only find tutorials on how to do this during initial install. I cannot find one that tell me how to do it after the install. Is there a way?

I am trying to use 3 3TB Western Digital drives in a raid 5 software array. The trouble seems to be that the array is created with only 1.5 TB of capacity, rather then the expected 6 TB.
Here are the commands and output:
$ sudo dmraid -f isw -C BackupFull6 --type 5 --disk /dev/sde,/dev/sdf,/dev/sdg --size=5589G
Create a RAID set with ISW metadata format
RAID name: BackupFull6
RAID type: RAID5
RAID size: 5589G (11720982528 blocks)
RAID strip: 64k (128 blocks)
DISKS: /dev/sde, /dev/sdf, /dev/sdg
About to create a RAID set with the above settings. Continue ? [y/n] :y
$ sudo dmraid -s
*** Group superset isw_cdjhcaegij
--> Subset
name: isw_cdjhcaegij_BackupFull6
size : 3131048448
stride : 128
type : raid5_la
status : ok
subsets: 0
devs : 3
spares : 0
So I cannot understand why the size of the created array is only 3131048448 or about 1.5 TB. The first command seemed to imply it was going to create an array with 5589GB.
System is:

I have a CentOS 5 based Linux system with a 3Ware 9550SU RAID card and four 500GB drives set up in a RAID5 array (3 in the array and 1 hot spare).
I want to 'replace' these drives with four 2TB drives without data loss. My server case has a total of 8 drive bays all hot-swap and all attached to the RAID card, this means I have four empty drive bays on the RAID card.
One thought is to put the four new 2TB drives in the empty drive bays, configure them in a new RAID5 array. Then the question is now to I "mirror" the original RAID5 array over to the new one?
This is just a thought though, I am not sure it will work. In short my question to this forum is how do I accomplish this upgrade?.

I'm trying to delete directories (long story, Mac temp files there, Windows not cooperating) on a sever connected to a HP 20 Modular Smart Array set up as RAID5. System currently running Windows. I've booted from a 9.10 LiveCD but can't see the external drives. Is it correct that I need to install mdadm to "see" those drives from LiveCD? From a different machine (linux) I can mount the drive using samba like so:
sudo smbmount //IP address/hostname RAID5 Root Share /mnt/ntserver -o username=smith,password=abcde123
I have admin privileges on the Windows OS. In linux (or Windows beforehand), is it possible to take ownership of the directories so that I can do a rm -f -r <dir> ?

I'm not entirely a newbie, but this seems like such a simple question I'm not sure where else to ask it. I checked through the various HOWTOs and searched already and didn't find a clear answer, and I want to know for sure before we start investing in hardware. Is is possible to create a RAID1 (mirroring only) array with 3 live drives, rather than with 2 live plus a spare? Our goal is to have 3 drives in a hot-swap bay, and be able to pull and replace one drive periodically as a full backup. If I do:

I have a home samba server with a 3ware Escalade 8506-8. I have 5 x 500 gig hard drives in a RAID 5 array. Recently, my 8506 died and I need to get a new one. However, I saw a 3ware Escalade 9500S-12 on ebay for about $20.00 dollars more than a replacement 8506-8.
My question is, if I put my drives on the 9500S, will it recognize my existing RAID array? Or will it want to build a new RAID array and format all of my data?Hope I have asked this question clearly, little short on sleep this week.
