3ware RAID Controller Blinking Red Light
Jun 6, 2009
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.

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.

MY server configure our drives with RAID-1.
How can I check it my server configure with 3ware or software raid ?
Also please advise me how can I monitor raid configuration that my raid is working fine or no ?

I am looking to hook up 4 WD Velociraptors to a Raid array. My #1 priority is speed, thus I will be doing RAID 0.
I'd prefer something from Canada.
I just thought of it, 4 drives on RAID 0 might not be a good idea ... Should I opt for RAID 5?

I'm used to 3dm controller, that I can access using HTTP, configure to send E-mail if one HDD shows error, and so on
now I'm using a FreeBSD server with RocketRAID RAID controller
anyone knows if it's possible to do the same as 3dm?

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?

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?

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 ..

We had one of RAID controllers failed on our IBM RS/6000 server. There are two RAID controllers on this server, one holds the OS (AIX) and the other one holds our database and this is the one that failed.
Anyway, I've always thought that once a RAID controller failed and we put in a replacement controller, it will reformat all the hard drives that were connected to the failed controller, which means we would have to restore the data from backup once the new controller is in place. However, the IBM technician we dispatched was able to build the new controller and connect all the drives to the new controller without reformatting the drives. I think he copied the RAID controller's configurations using SMIT. I think that was amazing; it saved us a lot of time.
My question is, is this something unique to IBM hardware/AIX or other hardware and OSes (Linux, Windows, etc.) have similar capability?

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)

This problem has happened to me twice on the very same server. I can't seem to figure out what's wrong with it.
My raid controller is Areca 1160 + 1GB Ram + 16xWD4000YS. Initially I had the problem of the disk dropping from the array randomly. I suppose this problem has been fixed since I have upgraded disks firmware according to WDC suggestion.
But there's another problem now. From my observation, the controller is randomly dropped off the system. When this happen, I cannot read/write anything from the disk at all. I can SSH in and able to run Areca CLI tool to see what's going on but only to get the message saying that it cannot find any Areca controller.
My only option is to restart the server and fsck all those 16 disks (not fun). I checked the log on the RAID controller itself, there was no sign of problem at all. No alert, no disk being dropped off the array, no events logged at all.
I'm using CentOS 4.3. Firmware on the RAID controller is 1.41, latest is 1.42. (Stupid me for not upgrading firmware when server crashed.) I plan to take the server down for RAID firmware upgrade soon. I just hoped that it's just problem with the firmware, not the controller or backplane itself.

I have been building a business around blogs and other social media items on mostly OSS technology - but unfortunately, my current reseller account is inadequate for what I need (especially with sites that query a DB) and unable unfortunately to upgrade to what I might need. I don't want to rip on them because they've provided me great service, but they're just not able to ramp up. My thought is there won't be any reseller to meet my needs after learning more info, so I'm going to make the leap up.
I'm not going to go pound the pavement for hosting business; this is only really for my clients I serve as a agency/consultant/designer and my clients need and deserve more.
I have been considering Mosso; but also weighing a dedicated box as it's around the same price and looking around here for the solutions people recommend for the past few hours. But since I sort of have a specialty application, I thought I'd ask for your recommendations.
I want to say that I came here from another forum because my provider was affected by the Planet outage and the conversation and knowledge was great; you are a very smart community. I hadn't heard of this place beforehand but am glad I found it.

Can anybody recommend a free or paid webmail application which can be used on a mobile (specifically a blackberry 8100). I need a way to access my emails via a webpage... I can't have all emails forwarded to my phone, as there are way to many. As there are a fair few emails in my inbox the application would need to be able to handle a large number of emails.

Is Motherboard RAID as good as a dedicated PCI-E card? I am guessing a dedicated card is the best option, though costs more.
We are looking at buying a barebones server from Supermicro. It features an onboard RAID controller which supports RAID 0, 1, 5 & 10 - but for some strange reason it will only support RAID 5 if you use Windows. Here is a link to the page detailing the RAID features.
[url]
We are going to be running Linux, CentOS 5.1, so we will only have the choice of RAID 0, 1 or 10. This isn't an issue, as having RAID 10 on 4x SAS (15k) drives will be fine for speed and stability. What is an issue is would this RAID controller be as fast or reliable compared to a dedicated PCI-E card? If it can only use RAID 5 in windows, does that suggest this controller is too reliant on software? It would be a nightmare to suffer downtime and data loss because the controller couldn't hack it during a drive failure, or one day it decided to bugger up the array when rebooting.
So that leads me to looking at this card, this looks very good for what we need. Are adaptec a reliable brand? I've seen it advertised for £200, which is a good price.
[url]
This card features RAID 5 and 6, would RAID 6 be better than RAID 10 for redundancy, or is it too slow to bother with? Also it seems to have a battery module available for it, what does this achieve? Cos surely if the power dies the hard drives and motherboard can't run off this little battery, or does it just help the controller stay alive long enough with some hard drive information in its memory if the power goes out during a rebuild?

I've only tried whmsonic shoutcast admin pro to create sc accounts
I used whm to create cpanel hosting accounts before so had an idea.
With whmsonic admin pro i was a bit lost, creating cpanel hosting
accounts so i could ad those features to shoutcst accounts
But from what i've read, cast control is more straight to the point
You don't need to be creatings cpanel accounts first etc etc.
Is there others that any of you have on your servers for setting
up shoutcast accounts with hosting for uploading audio files ect
Autodj and so on.

I could try the Software-RAID 5 of the EQ9 Server of Hetzner.
Does anyone here has experiences, how fast a hardware raid 5 compared against the software-Raid 5 is?
The i7-975 should have enough power to compute the redundnacy on the fly, so there would be a minimal impact on performance. But I have no idea.
I want to run the server under ubuntu 8.04 LTS x64.
On it a vitualisation like VMware the IO-Load could get really high.

So I've just got a server with 2xSATA raid 1 (OS, cpanel and everything in here) and 4xSCSI raid 10 (clean).
Which one do you guys think will give the best performance:
1. Move mysql only to 4xSCSI raid 10
2. Move mysql and home folder to 4xSCSI raid 10

I am in a somewhat complicated situation... I wanted to order a custom server with hardware 3Ware RAID controller but after over a month of waiting I was told the HW RAID controller, as well as any other 3Ware controller they tried, does not work with the motherboard used in the server from Fujitsu-Siemens and that they simply got a reply from FS that the controller is not certified to work with their motherboard.
So although I'd prefer a HW raid, I am forced to either choose a different webhost or setup a software RAID. The problem is, I haven't done that before and am somewhat moderately...scared
I have read a lot of the info about SW RAID on Linux that I could find through Google but there are some questions unanswered still. So I thought that perhaps some of the more knowledgeable WHT members could help me with this problem...
The server specs will be:
Core2Duo E6600 (2.4Ghz), 2GB RAM, 6-8x* 250GB SATA II HDDs, CentOS 4.4 or SuSe, DirectAdmin
* I prefer 8 HDDs (or actually 9) over 6 but I am not sure if their server chassis can hold that many HDDs, I am awaiting answer from them. They don't have any other drives beside the 250GB ones so I am limited to those.
The preferred SW RAID setup is to have everything in RAID 10, except for the /boot partition which has to be on RAID-1 or no RAID I believe, plus one drive as hot spare (that would be the 9th drive). I am quite sure they will not do the setup for me but will give me access to KVM over IP and a Linux image preinstalled on the first HDD so that I'll have a functional system that needs to be upgraded to RAID-10.
How do I do that? The big problem I see is that LILO or GRUB can't boot from a software RAID-5/10 so I will have to mount the /boot partition elsewhere. It's probably terribly simple...if you have done it before which I have not. I have read some articles on how to setup a RAID-5/10 with mdadm (e.g. [url] ) but they usually do not talk about how to setup the boot partition. Should it be setup as a small sized (100-200MB) RAID-1 partition spread over all of the drives in the otherwise RAID-10 array?
What about swap? Should I create a 4-8GB (I plan to upgrade the server RAM to 4GB in near future) RAID-1 swap partition on each of the disks or swap to a file on the main RAID-10 partitions. The second sounds simpler but what about performance? Is swapping to a file on RAID-10 array a bad idea, performance wise?
Is it possible to grow a RAID-10 array in a way similar to growing a RAID-5 array with mdadm (using two extra drives instead of one of course)? mdadm doesn't actually even mention RAID-10 despite it does support it without having to create RAID-0 on top of RAID-1 pairs if the support is in kernel, from what I know.
