Red Hat :: Adaptec Embedded SATA HostRAID Controller 7e On CentOS

Jan 10, 2010

I have been trying for a few days to install CentOS 5.4 on an IBM x306 and I cannot get it to properly handle the Adaptec Embedded SATA HostRAID Controller. I have been working with Linux for a few years, but this is new territory for me. I typically use Debian-based distros, but I did some research on the IBM site and found out that RHEL is a supported OS for this machine. So, I decided to give Cent a try. I have some experience with Fedora, so it's not totally foreign to me.

Anyway, I'm a bit confused. Using the IBM RAID utility, I set up a mirrored pair of 1GB SATA HDDs. When I run the Cent installer, it sees the pair as a single array. I am able to partition the array and complete the install, but when I boot into the OS, it sees the drives as 2 separate devices, sda and sdb. I can pull either one of the drives and boot with a single disk, but it doesn't seem to behave as a mirrored pair. If I make changes on sda, they are not replicated to sdb. Also, I can't use the cli or GParted to format the existing space on the array. I get an error either way. I believe this is because Cent doesn't have a driver for the RAID controller, but I don't see why it would work in the installer, but not the installed OS.

My next approach was to start over and attempt to run "linux dd" at the start of the installation. I tried to find the driver for the controller on the IBM site so I could load it when prompted, but couldn't find a newer version than RHEL 4 Update 3 (I'm assuming this would coordinate with CentOS 4.3). I tried it anyway, but when I select the floppy during the setup, it tells me it's not for this version of CentOS. I read several times that there are .img files that might help me in the 'Images' directory of disk one, but I only see diskboot.img, minstg2.img, and stage2.img. I don't think any of these are what I'm looking for. I thought there was supposed to be a drvblock.img or driverdisk.img.

Hardware :: Give Centos Drivers For Embedded SATA Raid Controller On HP Proliant?

Feb 5, 2010

I forced my workplace to forgo windows and opt for linux for web and mail server. I'm setting up Centos 5.4 on it and I ran into a problem. The server machine is a HP Proliant DL120 G5 (quad core processor, 4GB Ram, two SATA drives, 150GB each attached to the hardware RAID Controller on board). RAID is enabled in the BIOS.I pop in the Centos disk and go through the installation process.

When I get to the stage where I partition my hard drive,it is showing one hard drive, not as traditional sda.but as mapper/ddf1_4035305a86a354a45.I looked around and figured that I need to give Centos the raid drivers. I downloaded it from:

[URL]

I follow the instructions and download the aarahci-1.4.17015-1.rhel5.i686.dd.gz file and unzipped it using gunzip. Then on another nix system, i do this:

dd if=aarahci-1.4.17015-1.rhel5.i686.dd of=/dev/sdb bs=1440k Note that I am using a usb floppy drive, hence the sdb. After that, during centos setup, i type: linux updates dd

It asks me where the driver is located. I tell it and the installation continues in the graphical mode. But I still get mapper/ddf1_4035305a86.a354a45 as my drive. I tried to continue to install centos on it. It was successfull but when i do a "df -h" it gives me /dev/mapper/ddf1_4035305a86......a354a45p1 as /boot

/dev/mapper/ddf1_4035305a86......a354a45p2 as /
/dev/mapper/ddf1_4035305a86......a354a45p3 as /var
/dev/mapper/ddf1_4035305a86......a354a45p4 as /external
/dev/mapper/ddf1_4035305a86......a354a45p5 as /swap
/dev/mapper/ddf1_4035305a86......a354a45p6 as /home

Well i know why it's giving these, because i set it up that way, but i was hoping it would somehow change to the normal /dev/sda, /dev/sdb. That means that the driver i provided did not work. I have another IBM server (5U) with raid scsi drive and it shows the usual /dev/sda. It also has hardware raid. So i know that there is something wrong with the /dev/mapper/ddf1_4035305a86......a354a45p1 format.

First, is there any way that I can put the aarahci-1.4.17015-1.rhel5.i686.dd (floppy image) on a CD?. I really need to set this up with raid. I know i could simply disable raid in bios and then i would get two normal hard drives sda and sdb. But it has to be a raid setup. Any way to slipstream the driver into the centos dvd? The hp link i provided above, under installation instructions, there are some instructions titled "Important". But I couldn't get it to work.

CentOS 5 :: Installing The SATA RAID Controller?

Mar 19, 2009

I'm working on a new server and it has an Nvidia SATA array controller with 2 250Gb SATA drives configured in a hardware array. When the first screen comes up I'm entering the option Linux DD for it to prompt me for the drivers but nothing ever happens. The screen says that it's loading a SATA driver for about 15 minutes and then the screen clears and has a plus sign cursor on a black screen. What am I doing wrong? The only driver that came with the HP server are for Redhat 4 and 5 and SUSE, will any of those actually work?

CentOS 5 Hardware :: Marvell 88SE6121 SATA II / PATA Controller

Sep 29, 2009

On an Asus P5Q motherboard, CentOS 5.3 x64. (Separate thread as the other one has turned into just a discussion on my lm_sensors issue). The motherboard's primary SATA controller is the Intel P45 chipset. 6 ports, set to AHCI in BIOS, and all works a charm. Attached are 6 x SATA drives (2 x OS, 3 x data RAID5, 1 x backup). There is also a Marvell chip that provides PATA and also an underlying SATA chip (2 ports) that can do what Asus call Drive Xpert (stripe or mirror RAID) or be set to just standard SATA ports.

It's a SIL5723 behind what CentOS sees as "03:00.0 IDE interface: Marvell Technology Group Ltd. 88SE6121 SATA II Controller (rev b2)". Physically the Marvell has only a single optical drive attached to its PATA interface. CentOS has loaded marvell_pata (I assume for the PATA side of it) but I have no /dev/cdrom or /dev/dvd so no optical drive CentOS is trying to use 'ahci' for the Marvell's SATA ports. Dmesg tells me that when it 'sees' them as it boots:

scsi6 : ahci
scsi7 : ahci
scsi8 : ahci
ata7: SATA max UDMA/133 abar m1024@0xfeaffc00 port 0xfeaffd00 irq 16
ata8: SATA max UDMA/133 abar m1024@0xfeaffc00 port 0xfeaffd80 irq 16
ata9: DUMMY

It attempts to read SATA drives attached to it, but it just errors trying to access them on boot (e.g. "ata7: failed to recover some devices, retrying in 5 secs" etc). I need the extra SATA ports, and I could really do with having a usable CDROM drive. I found a driver for the Marvell 88SE6121 from Asus. But the latest driver in that is for what it calls "RHEL 50.2" and the script fails with a "Generic Protection Error". That driver looks for kernel "2.6.18-92.el5" in its base_ver variable in the script. Changing the base ver to -128 doesn't help. I have uploaded the driver for if [URL]. Is that modifiable to work on 5.3 / soon to be 5.4?

Fedora Installation :: FC 10 Live Cd Is Not Seeing Adaptec Raid Controller

Jan 29, 2009

I am trying to install FC 10 on my built-in Adaptec raid controller and the Live CD does not see the controller.From my other ATA drive FC10 install I get this from lspci -v:

Adding driver was successful, but I got some error during the build

Am installing Fedora 10 on an old but good server that used to be a windows box. It has 2 sata disk raid level 1 on adaptec 2410SA card. Disks are clean no info even did a low level format and recreated RAID.. twice DVD boots and installs os on raid array and reports success. new volume appears under computer icon but cannot be mounted after reboot attempt reports Reading physical volumes.

Debian :: Using Apt-get For An Embedded Controller?

Jul 21, 2010

I've bought a small embedded controller running with a minimized Lenny for armel. Minimized in a way that there is even no apt-get or dpkg installed on it, due to keep the memory footprint as small as possible.Is there a way to keep a "shadow" system in a directory on my Laptop (e.g. ~/armel), maintained with dependencies by a package manager like apt-get? This would allow to install addition packages including all dependent with a simple apt-get call.Of course, later I have to put the whole tree from my Laptop towards my embedded controller. I've already tried the following:Setup a directory tree behind ~/armel for apt by a copy from my laptops Lenny

"sudo apt-get -o DIR=~/armel -o APT::Architecture=armel update"
to get the repositories, this works fine
"sudo apt-get -o DIR=~/armel -o APT::Architecture=armel -d -f install"
to download the full list of .deb packages, this works fine

Hardware :: Is LSI Logic RAID Controller Embedded Or Not

Dec 20, 2010

I have been using lspci, dmidecode, and mpt-status to get hardware information on my Dell 1950 running Ubuntu 8.10. I'm pretty sure my server is using an embedded SCSI RAID controller from info I got from Dell's site:

1CR679Assembly, Card, SAS6IR, Integrated, Sled
1TX846Assembly, Cable, Controller SAS, POWEREDGE EXPANDABLE RAID CONTROLLER

When I run lspci I see:

01:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08)

PCI-Express is an actual...well, PCI card, right? But dmidecode shows that I have two x8 PCI Express slots that are both available. Sooo...I'm missing something. How am I running a PCI Express SCSI controller without using a PCI Express slot? In the event of not having the kind of info that I did (i.e. the service tag) how would I be able to tell at a glance whether a component like my RAID controller was embedded or not?

CentOS 5 :: Eucalyptus Node Controller And Cloud Controller Apps Won't Bind To IP

Jun 18, 2010

I can not get the node or cloud controllers to startup using the init.d scripts. I have a fresh install of CentOS 5.4 with Eucalyptus 1.6.2 I have compiled Eucalyptus and all packages using the RPM supplied from Eucalyptus and utilizing yum installer. I do not currently have any processes or applications listening currently on the ports on the boxes as well. I think it may be a permissions issue or something because I get a "permission denied error", but I am not sure if it is Eucalyptus or CentOS. It looks as if it is not binding to the address on the interface of the NIC. It may be something else however. I have the Node controller, Cloud controller, and Cluster controller on seperate physical boxes. When I try to run either the cloud controller or the node controller I get this message:

Cloud Controller:

CentOS 5 Hardware :: Installing CentOS 5.4 X86_64 On Adaptec RAID 3405

Jan 13, 2010

My problem is that I'm trying to install CentOS 5.4 x86_64 DVD ISO on Supermicro X7SBI server with installed Adaptec RAID 3405 controller.

I created RAID 5 array and is working fine (adaptec status says Optimal) but I can't install CentOS to that array (1.5TB size).

Whenever I try to install with: linux dd

I'm asked for a driver, which I have downloaded from Adaptec site and extracted contents to USB drive (in installation found as /sba1) which has now a lot of IMG and some ISO files on it.

I try to load (I simplified names) RHEL5.img, CENTOS.img... with x64 names (one exact name: aacraid driverdisk-CentOS-x86_64.img) and I always get the error message: "No devices of the appropriate type were found on this driver disk"

This is going on for a week now and I can't find the right driver or something I'm doing wrong to get install done.

OpenSUSE Hardware :: ATI SB700/SB800 SATA Controller

Here's my lspci:

uname:

This is happening on three out of three SATA disks in the system and, even though I can't explain how, seems to have caused data loss on the mdraid they support.

It would be great if someone has a good idea on this one.

adding smartctl -a, just in case

After scanning selected spans, do NOT read-scan remainder of disk. If Selective self-test is pending on power-up, resume after 0 minute delay.

Fedora Hardware :: Gigabyte GA-H55M-UD2H SATA Controller

Aug 18, 2010

A friend of mine bought a prebuilt system from a local computer store that has the Gigabyte GA-H55M-UD2H motherboard and he says he can boot Fedora off the CD but cannot install it as it doesn't detect the harddrive.

I assume it can't detect the SATA Controller as I am pretty sure hard drives use a universal driver so the only way for it not to detect the hard drive is if the controller is not detected.

I was wondering if anyone here has this motherboard and has this problem.

I think I gave him a Fedora 12 CD. (EDIT: It's Fedora 11 judging by the filename of the ISO I have on my Desktop...)

I myself haven't used Linux in a while since I completed my Linux course and this game I play needs Windows, but I am trying not to play that game as much anymore though because of free time issues... I have an Ubuntu Dualboot but have become used to Windows again. I am gonna try using Linux in a VM to get accustomed to it again, this way I can play with different versions/distros and still have the Windows 7 host as a fallback is something doesn't work...

I'm not all that familiar with what it is that the expensive SATA cards do, other than providing on-board cache and many ports, but all things considered what can't a CPU and lot's-o-RAM do that an expensive SATA card can?This assumes, of course, that you weren't planning on using the CPU to run other applications (i.e. a SAN type setup).

Ubuntu Servers :: Mdadm RAID 6 Array With Si 3132 SATA Controller ?

Mar 12, 2010

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.

OpenSUSE Install :: Error 11.2 On Raid 0 / EM2001 2 Poorts PCI Controller SATA Fails?

Mar 1, 2010

I want to stop using Windows because it sucks so i have downloaded all kind of distibutions from Linux. They give all the same error because it seems Linux has problems with Fakeraid. Now i have running OpenSuse in VmWare 7.0.1 but i want it as the only OS.

The installation goes fine but in the end it gives a Grub error because it cannot create the bootloader. It seems to be a common problem and i have done all the steps that i could find on Google.

I have two raid controllers. One is integrated in the mainboard from Asrock ALiveNF7G-HD720p R5.0 and OpenSuse sees it as a Jmicron controller.I have bought also a EM2001 2 Poorts PCI Controller SATA card with two harddisks in Raid 0 because Linux failed to install on the JMicron. On the EM2001 2 Poorts PCI Controller SATA it also fails with the same error.

I want OpenSuse 11.2 working on Raid 0. I know it must be some simple commands in the terminal through a live cd to correct the bootloader and do it manualy by Linux users but i'm a Windows user.

Can somewhone please tell me the exact steps and commands to install Linux on Raid 0 Fakeraid?

OpenSUSE Install :: Find Hard Drives On System - Motherboard With Two SATA Controller Chips

Aug 2, 2010

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?

CentOS 5 Hardware :: Adaptec SCSI RAID 2100S Adapter On 5.5

Has anyone successfully used an Adaptec 2100S in a RAID configuration? Specifically, RAID1?

Drivers exist for earlier version of Red Hat, but building an using a driver disk results in the error:

Driver disk is invalid for this release of CentOS

CentOS does not recognize the adapter out-of-the-box as a HW RAID controller, but does recognize the individual disks.

I attempted to use software RAID, but the installer craps-out after a while and the screen locks up.

CentOS 5 Hardware :: 5.6 + Adaptec 5805Z And LSI Expander + Raid 6 Poor Performance

Jun 30, 2011

I installed on a Intel SR2612UR Server with integrated LSI Expander and a Adaptec 5805Z controller a Raid 6 Array with 12x 2TB Drives (2 ext4 Partition: 16TB, 2TB), but I get very poor read speed depending on the blocksize that I set it vary between 130 MB/s and maximally 170 MB/s which is really poor for a Raid 6 Array of 12 drives, on a similar Dell Server I get above 650 MB/s. The Adaptec Controller has the latest Firmware installed.
