3ware "multiple Card Support"
Jan 7, 2007
I am configuring a new file server, with 11 drives and two 3ware 8506-8 raid cards.
I would like to have one hto spare shared between the two cards.
I have read on the docs that 3ware have "multiple card support" but I don't find anuthing in the documentation stating how to have two cards managing one big array.
Is it actually supported or the "multiple card support" term is just a marketing leadout to state "you can put two card in a system without conflict"?

When trying to load an ovzkernel it loses support for the 3ware 8006 controller. As suggested on ovzforums, it says to load the new 3dm2 tools. I tried this but when I try to install it, it says it can't find the 3dm2 binary.

I am not sure exactly which model is in my server, but I know it is in the 3ware 8xxx line.
What is my best option to be alerted to a drive failure. I am running a Raid 1 setup.
I went to 3ware's sight, and wasn't sure exactly which software to download/install.
I am on Centos 5.2 32bit and have Cpanel/WHM installed.

I have apache 2.2.9and currently running a filehosting community. Though the connection for download manager are only set to 1 and does not support resuming. Is there any add-on or script that can support 5 connection and resuming?

I am using aplus.net to host a WordPress blog and want to create more blogs.
Since aplus.net took 26 hours to restore my blog when somehow it was corrupted (no explanation on what they did), I have decided I need to host it someplace where I have full control.
I would be prepared to reinstall WordPress on my own. I also want to have the ability to control redirects. aplus provides a handful of very weak tools for managing the site.
I'm looking for a host that would allow me to manage multiple domains, and multiple instances of WordPress. I'm prepared to manage the MySQL db (if I have to, though I would prefer it if I had support for this).

A really nice feature has been brought to plesk with the native support for multiple PHP versions now.I tried it out, but there seems to be an error in the session.save_path of PHP 5.5.23 (the one I tested).sessions.save_path points to /var/lib/php/sessions but the default before seems to be /var/lib/php/session so the folder does not exist.For now I simply worked with a symlink to solve the problem:
cd /var/lib/php/
ln -s session sessions
Not sure if other PHP version or other OSes (besides PHP 5.5.23 and CentOS 6.6 are affected).

Of the three raid card brands, which do you think is best and why?
I'm currently looking for a card that can do both SAS and SATA, and have four internal ports.

I have installed 3dm for checking 3ware 8086 card status, but when going to [url] it doesnt show anything. It seems cannot connect to 1080 port, even I have turned off the firewall. Have checked in its config file already to make sure the port is 1080
Is there anyone having experience with 3dm software?

I downloaded the latest 3dm2 software:
wget [url]
However, after extracting it, when I run the setup (./setupLinux_x64.bin -console) I get "Bundled JRE is not binary compatible with host OS/Arch or it is corrupt. Testing bundled JRE failed."
Can anyone give me the steps for installing 3dm2 on a centos/WHM box?
The card is a 3ware 9690SA.

Not sure if this is too specific for this forum or not, but since I've gotten great advice here in the past I'll give it a shot.
I have a colo'd production server with a 3ware 9500S-12 RAID card and 12 400GB drives attached. The drives form 3 arrays:
1) 2 drive RAID 1 (400GB)
2) 2 drive RAID 1 (400GB)
3) 6 drive RAID 5 (2TB)
plus 2 global hot spares.
For a variety of reasons I need to change this setup so that array 1) and 2) remain as is, and array 3) is removed and those 6 drives replaced with 6 new 750GB drives in JBOD mode. I've copied all the data from the RAID5 array number 3) onto 3 of the new 750 drives (the 2TB array wasn't completely full,) and I have 3 other blank 750GB drives.
What's the best / safest way to do this? Ideally I'd like to remove the 6 old 400GB drives and retain the ability to plug them all back in and get my old array back (if something goes horribly wrong doing the switch.)
Do I need to reboot into 3BM (3ware Bios Manager) to do this, or can I do it from the command line?
Is there any problem with having a drive that already contains data written to it by another system, and bringing it up on the 3ware card in JBOD mode with the data intact? (All filesystems are ext3.) I'm not going to have to reformat the drive, am I?
Is there any problem with the new drives being SATAII (Seagate Barracuda ES 750GB) but the old drives (and I think the 3ware card, and certainly my motherboard) being SATAI? I've read that this should "just work" but of course I am nervous! There are no jumpers I can see on the 750GB drives.
Will it be possible to remove the RAID 5 in such a way that I could plug the drives back in and get the array back?

I have a bunch of 3Ware 95** RAID arrays with BBUs. Lately the BBUs are sensing high and too high temps a lot.
The dc reports that intake temp is 74 degress and exhaust is 91 degrees. Since the RAID cards and the BBUs are at the back of the machine, its getting more hot air than cool.

Probably going to give this a shot in the near future anyway, but just wanted to check whether anyone has tried and had success putting either 3Ware 8006-2LP or 9550SX-4LP cards in Dell PowerEdge 860 systems with a couple of SATA drives instead of using the Dell PERC controllers?

we use 3Ware's 8006-2LP sata raid controller in each of our servers for RAID1. Our servers are all Supermicro boxes with hot-swap driver carriers (ie. the 2 raided drives are in them)
One of the drives appears to be starting to crap itself as smartd is reporting issues (although tw_cli c0 shows the raid to be OK) incl. multi zone errors.
Anyway, I'd like to replace the failing drive before it becomes a real issue so i've bought a replacement (74gb raptor, just like the original) drive.
Now I've never had to replace a failing drive in any of our servers before and I used to think it would be a simple matter of simply popping out the failing drive's carrier, put the new drive in the carrier and stick it back in the server... and the raid controller would do the rest.
Yes a little naive I know but i've never had to do it before so never paid much attention .. Anyway, I've just read and re-read the 3ware docs for my controller and their instructions are VERY VAGUE ... however I do get the feeling that the process is move involved ie. I need to tell the controller (via cli or 3dm) to first 'remove' the failing drive from the raid ..and then add a new drive and then rebuild
However there is one catch .. 3dmd/3dm2 has NEVER worked on our (centos 4) servers - 3dmd crashes regularly and 3dm2 never worked. So yes I am stuck with the 3ware cli ... which I don't mind as long as someone can tell me the sequency of commands I need to issue
As this point I'm thinking what I need to do via cli is
1) tell raid controlloer to remove the failing drive on port 0
2) eject the drive carrier with the drive in question
3) insert new drive in carrier and re-insert into server
4) using tw_cli tell the controller to add the new drive to the array and to rebuild the array
Am I anywhere close to being correct? I'm sure there are some of you out there who've done this countless times before with the 3ware controllers and hotswap drive carriers ..

I'm seeing the following from dmesg:
Quote:
3w-9xxx: scsi0: AEN: INFO (0x04:0x0053): Battery capacity test is overdue:.
When I'm in the CLI console (tw_cli) and tries to test the battery, I'm seeing the following:
Quote:
//vpsXX1> /c0/bbu test
Depending on the Storsave setting, performing the battery capacity test may
disable the write cache on the controller /c0 for up to 24 hours.
Do you want to continue ? Y|N [N]:
This is a live production server with client VPSs on it. Anyone here actually did 3ware battery test before on production system? Is it ok to do this? I'm seeking someone actually performed test operation before, not from someone just assumes it will be ok.

I have a 3ware 9650SE-24M8 RAID Controller. It was working fine for a few days and today while I was changing the RAID configs and installing different OSs, it just stopped working. Now when I boot my machine up it does not even detect any hard drives or RAID controller. I looked inside the box and the LED light on the RAID controller that is usually solid green is now blinking red. I googled for solutions but all searches lead me to useless information such as blinking red lights on the server case.

After seeing a topic a week or go discussing RAID cards I decided to give a hardware raid card a go to see if the performance will increase in one of our boxes.
Just for the simplicity of the test, I have put them into a RAID0 formation for purely performance tests and no redundancy. I choose a 3ware RAID card and went for the 2 port 8006-2LP option rather than the 9600 (as they had the 8006-2lp and risers in stock and what I've always been told is that SATA1 and SATA2 is really a selling point rather than any performance increase but we will leave that argument there). Because we run mainly Windows systems, I have put on Windows Server 2003 x64 R2. What I am finding after installing it all is it seems pretty "slow".
The rest of the hardware is a Dual, Quad Xeon (E5410x2), 8GB ram on a Tyan motherboard. Hard drives are 160GB Western Digital 7200 RPM so I can't see quite why it feels like its not running at a peak level.
Does anyone have any applications or software to give this RAID array a test as I really don't want to order any more or roll them out on to the network to find that software raid would be a better improvement. I did try a burn in app which tests everything but it according to the 20 seconds I ran it, in average it only transferred at 2mbs.. That cant be right..
I think one possibility is the RAID drivers arn't installed correctly as its still coming "Unknown Devices" in Device Manager and it seems It wont let me manually install the drivers for the 3ware device as it doesn't like the OS even though I have the correct ones and it installed Windows with it fine (a bit longer than normal anyway)

I'm planning to run RAID 1 on my PowerEdge 860 server running CentOS 4.4 (320gb x 2 SATA II).
After doing much research, I've decided to go with 3ware 9550sx.
I have some questions regarding installing the 3ware on an existing system with an OS already installed - How do I go about doing it?
I've read that CentOS 4.4 already has the drivers for it.. Do I just configure the RAID config during the boot up?
Is this an overkill for my PE Pentium D 2.8GHZ ?

I have configured a Xen setup on a dual xeon system with a 3ware 8506 2 ports sata controller.
Array is configured in raid1 and I am using LVM.
I get really slow accesses on the virtual machines, when I create a big ext3 system, the system is nearly freezing.

I have two domains as virtual hosts on same IP address.
I am getting certificate error for the second domain when I try to check email (using MS Outlook). I can't permanently "accept" certificate, it complains again and again. Certuficate I created and self signed for imap.domain1.com, but the second email server is imap.domain2.com, so it complains.
How do I set separate email certificates for two domains? Is it possible at all?

Depending on where u are at on my site (documents pages, training, main root, etc.) will depend on which type of background, footer, header and the like you'll get. Now I was thinking. Is there a way to have multiple error messages for more then one page depending on where you are at on a site? Right now it's intranet site and a modded snitz forum. What is the code and were does it go and in which apache conf file(s) does it go in?

I was building a 1u server a month or so ago to colocate. After screwing up the purchase of the raid card (got a pci 64 or something) its been sitting next to me not doing much. I need to go ahead and find a good raid card and get this colocated,
I have literally spent hours on Newegg, Amazon and Ebay and found nothing that really jumps out at me. When people were helping with the build before, Adaptec was recommended, but the card is now deactivated on newegg so I am looking again.
