3Ware tw_cli getting DEGRADED and ECC-ERROR on rebuild ...
3ware 9750 on Ubuntu
I'm setting up my first server so I can start taking control of all my data. The (used) server I picked up is a SuperMicro CSE-846E16-R1200B and it has a 3ware 9750 RAID card installed. I'm currently trying to run ubuntu 18.04 from another drive that's not part of the RAID array and I can't seem to get the 3ware 9750 to be recognized by the OS. I'm a moderately knowledgeable linux user. I'm also hoping to also become a proficient during this process, however, I can't seem to move beyond this point. The 3ware 9750 PCI card is recognized and it apparently has a correct looking kernel drivemodule.

From my troubleshooting, the tw_cli is the way to configure the RAID. Using this utility, it cannot find the controller.
$ sudo ./tw_cli //ubuntu> show No controller found. Make sure appropriate AMCC/3ware device driver(s) are loaded.
Here's to hoping someone knows more than myself, Cheers!
Long story short i need a way to automatically monitor 3ware RAID controllers at work. I've attempted 3DM2 but cannot access it via any browser (local or otherwise). System is a Dell Poweredge 1425, no support from OpenManage as the controllers are 3ware. Anyone familiar with other monitoring utilities that can work with 3ware?
RAID Card (in JBOD) says ECC error, FreeNAS says array is healthy. Who is right? What should I do?
Title is TLDR, but here's more details: Running FreeNAS 11.2-RC1. Everything is working great as far as FreeNAS is concerned. On a cursory check of the array, I noticed that one of the two RAID cards is showing a drive has an ECC error but hasn't tagged that drive as failing. I've tried manually forcing the controller to do a consistency check and it persists but FreeNAS still shows everything's OK. The controller is a 3ware 9750-8i. The question is, does this mean the drive is dying or does it mean there's an issue with the controller? I've never seen a failure like this, normally I'd expect the controller to drop the disk and then have an alert from FreeNAS saying that the array is unhealthy however this doesn't appear to be the case. Your advice is greatly appreciated, thank you.

Please help me troubleshoot my 9650se-12ML controllers
Hello everyone. I am hoping to find some help here. Not sure if or where I am going to cross-post this. I recently purchased some 3ware 9650se-12ML RAID Controllers with BBU units. The listing warned that the batteries themselves might need replacing, but I these are working units with good reviews and many sold. I purchased 4 and am experiencing these problems with all the controllers. The BBU is not working, and that is the ultimate issue. I am observing this in multiple places. When I boot the card I see two concerning messages in the BIOS splash screen. 1. BBU Status: Incompatible and 2. 3ware BIOS not installed. I will include a picture of this. I have installed the Windows 7 drivers and also the 3DM2 software to easily manage these cards. In the 3DM2 panel, the BBU Status is reported as Disabled. I will include a picture. I have tried to update to the latest BIOS I can find on the website. I really can’t figure out what is going on here. I have spare batteries that I have tried to swap into these units with no luck. I was hoping it would just be a dead battery, but no luck. I have tried these cards in a Dell Optiplex GX620 and two different gaming rigs with Asus motherboards. Same results with all cards on all machines. Please let me know if I can provide any useful information. I feel like this is user error since everything is so consistent. I included an album of screenshots for information. All help is much appreciated! https://imgur.com/a/AT3SX
Win Server 2k8 hangs/deadlocks on disk ops - RAID 1 drive dying?
So I've got a Windows 2008 R2 server with a couple of mirrored RAID drives that has been plugging along for months without any perceptible issues. Earlier this week I remote'd into it (it's normally headless) and it was unspeakably slow. Fearing the worst, I made a note to back it up on Friday after everyone was done at the office. Now it won't even respond to RDP. I threw a monitor and KB/Mouse on it, and I can log in, but it's ungodly slow. Task manager reports 98% System Idle, so it seems like it's all in the disk. I attempted to drag some files across the network, but even the act of trying to do that, I get about 250 megs copied, then the server deadlocks and stops responding to SMB and even ping. I'm wondering if one or both of the RAID 1 drives are dying, but never having actually had a piece of a RAID die, I'm not sure how to diagnose or troubleshoot it. Any advice?
Batch job won't write to txt file, unless in Admin group.
If this is the wrong subreddit, please let me know and i'll repost on the right one. So long story short, i'm working on a batch script that should check the RAID health status for a 3ware controller. It will be used via Task Scheduler, and the account used is LOCAL SERVICE (we cannot have cached passwords on this box for PCI reasons). The box is a domain controller. the DellSMTPNotify application is a mail program, and the parameter it's fed is a condition code for alerts. Also worth noting, the account is given the "Run with highest privileges" flag in Task Scheduler. The batch text is as follows:
cd C:\RAID Monitor\TW_CLI
tw_cli.exe /c0 show | findstr "OK" > OUTPUT.txt
find /c "OK" OUTPUT.txt
cd c:\RAID monitor
if "%errorlevel%"=="1" (
) else (
Most of this is working fine, however, if the LOCAL SERVICE account is NOT in the domain admins group, it does not write the tw_cli output into OUTPUT.txt, thus throwing the whole script in disarray and it won't actually check the status to email an appropriate alert. If LOCAL SERVICE IS in the domain admins group, this is not an issue. I have adjusted the security on all folders needed by this batch to let LOCAL SERVICE write to them as needed, but no dice. What i'm curious on is the reason WHY it needs to be in the domain admins group. It doesn't make much sense to me. Thank you, and have a great weekend.
I recently obtained an old custom-built server for the grand sum of £1, which came with a 3ware 9650SE RAID controller. I've installed the scsi-3w-9xxx VIM, which has let VMWare see the controller and use the arrays on it. These were configured through a copy of tw_cli I found on the internet. Is is possible to get the controller's status to show in VMWare's "Health Status" page? I know this is possible as I work with HP and Dell servers that have all the information there, but the only thing showing at the moment is the processor cache sizes (It's an L5410) and the software components. On a similar note, is it possible to change the make and model from "empty empty" and "To Be Filled By O.E.M." to something more useful?
About this CLI Guide This manual, the 3ware SATA+SAS RAID Controller Card CLI Guide, Version 10.2, provides instructions for configuring and maintaining your 3ware® controller card using the 3ware command line interface (CLI). This manual describes CLI support for the LSI 3ware 9750, 9690SA, and 9650SE with Release 9.5.2 or newer. 3ware. For monitoring the RAID status of a 3ware RAID controller, the best solution is to use the 3ware command line interface (tw_cli). Examples of Commands Requesting Information. Listing all obstructed 3ware RAID controllers: Driver for the 3ware can't be found automatically so i did use the driver install from 22.214.171.124 cd, and the drive i made in the controller BIOS is found and can be used (although being damn slow: 80MB write, 320MB read with h2testw. The same disks on the onboard SATAs with Win10 Soft-RAID give it 350MB write and 480 read per second. tw_cli is a RAID monitoring utility to help you maintain your 3Ware RAID array We use RAID-1 mirroring, so all of the information here relates to RAID-1, though some of it may be useful for other RAID types. 3Ware 9600S-8 Card tw_cli. These are the steps which I did to resolve the issue and get everything back into working order. First we’re going to remove the DEGRADED or FAILED disk. Find the failed RAID drive. Each of my servers has a different cX card number, so I always issue a show first to find the RAID card, and then find the failed drive
