Where to get/download LSIUtil

Friday, March 22, 2013

LSIUtil is a handy tool for configuring some LSI RAID controllers, including the SAS 6/iR I have in my Dell box:

LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08)

I'll leave the usage guides to others, but I'll mention one issue I had. I recently ran into Redhat Bug 512613 - Smartmontools cause hard drives behind a SAS controller to get dropped (or perhaps a similar bug), where I used smartctl to query /dev/sgX which promptly knocked one of my drives offline. The controller (via mpt-status) reported the disk to be MISSING and OUT_OF_SYNC, and Linux could not see it at all. I tried all kinds of things, but in the end, even LSIUtil and reboots did not fix it and I had to go to the datacenter, physically disconnect the "missing" drive, and then reconnect it. At that point, the RAID array began resyncing.

In the process, I found that an authoritative copy of LSIUtil is incredibly hard to find online. Here are the two newest copies I could find on LSI's servers:

Hope this helps someone.

Thanks for the links, it got me through when I needed it. But I just found a copy of the 1.63 source, hopefully this can help other people in the future:

Excellent, this util was perfect for me to change Link speed for an LSI card on a Dell server, able to set Min and Max Speeds to 3.0Gbps and at least get new SSDs in a server operating at 3Gbps instead of their negotiated rate of 1.5Gbps. Nice work.

I've found this:


this last one has source and changelog

ssl certificate is for other domain.

I don't know how trusty is the site, and can't confirm that source and binaries are authentic from LSI and not modified.

Thanks for the links adlib. I allowed a temporary ssl session to this site and have downloaded and tested lsiutil 1.71, specifically the amd64 version (which ran fine from win 7 x64). It seems to work, so hopefully this isn't some sort of PHY microcode hardware trojan or mpt_linux fw hack or something :-)

I'm trying now with enabling write cache on the onboard lsi 1068x of my HP xw8600.

When I first got this system I didn't use the RAID. Then my main disk went bad. Luckily I was able to save all the data, but decided to use RAID in the future whenever possible from then on.

Now I have 2x 2TB SATA 3Gbps on the LSI 1068x, and ever since I first got that setup it seemed slow. I tried updating to newer FW on the LSI (resulting in non-functioning, which I was luckily able to fix by reflashing the original fw), but it didn't seem to help. In fact, anytime anything write intensive happens the entire system will literally stop for long periods. I found that to be a shame because the system seemed so quick and peppy before. I think that the better answer here would be OS optimization. Why is the OS trying to write-cache when it is disabled? That is just about how it feels, anyway.

Lately it has seemed worse, so, today I try this! I am positive that each drive has a nice big fat (physical) cache, and I want it turned on! It was put there to enhance performance, so lets use it!

Too bad that the HP version of the FW doesn't bring out features like cache enabling the way most dell or lsi fw's do. Thanks to your link I can access those options!

Darned if the computer doesn't feel a hundred times faster already! The whole system feels more available and not like it's constantly waiting on something to end or interrupt.

Mikhail Shevtsov on Thursday, February 6, 2020 at 10:32

Thank you for the utility.

After installing Samsung SSD EVO 840 to Dell PowerEdge R610 with SAS6IR controller I've faced really nasty glitch which made SSD Super Extremely Slow. Even slower then HDD with extremely high svctm. I've followed "tutorial" and managed to get around 300MB/s read speeds from this old server:

P.S. I've used System Rescue CD v5.3.2 in 32-bit mode to get lsiutil running.
