I have an LSI HBA connected to an Intel RES2SV240 SAS expander which has been working beautifully for a number of years now.
I’ve completed an update to my TrueNAS box today, and when powering it back on, only devices connected directly to the HBA are detected, and nothing is detected via...
I'm wondering if someone can give me some pointers as I'm revisiting doing this myself but struggling a bit;
I have a custom build server running ESXi 7.0 U2, with a Quadro P400 connected.
I have the Quadro passed through to my VM, but even with R471 driver, I got Error 43, so had to add the...
Thanks for that!
How does the duty cycle interact with temperature thresholds?
I.e if I set a specific duty cycle to 50%, and CPU temps spike, will the duty cycle increase in line with that or stay at the 50% mark?
Also, do the fans need to be set to "Full Speed" mode before adjusting duty...
I know there is a lot of info out there about SuperMicro IPMI fan speed control and threshold adjustment, but it is somewhat beyond me.
I am curious to know if it is possible to define custom fan curves and settings?
My understanding of how IMPI handles thresholds and controls fans is...
Here is my sensor output during a period where the fans oscillate:
CPU Temp | 24.000 | degrees C | ok | 0.000 | 0.000 | 0.000 | 95.000 | 98.000 | 100.000
System Temp | 23.000 | degrees C | ok | -9.000 | -7.000 | -5.000 | 80.000 |...
IIRC, setting to full speed runs them at full all the time without issue, but I don't really understand the concept of the duty cycle enough to tinker with this, so not really sure what I'm doing there.
I can't be certain, but I think if I set it to standard, they all run at lowest RPM without...
No all the fans are 4 pin PWM fans.
I did have 2 of the 80mm fans on a 4 pin to 4/3 pin splitter which I thought was the problem, but that wasn't the case as I connected just one of them directly to the header and it still does it.
Definitely feels like a threshold issue, but none of the lower...
They don't ever report 0rpm.
They show as the lower bound for these fans, which is about 375 rpm, then after couple of seconds they ramp up to max speed which is about 1200rpm and 1950rpm, then a couple of seconds they lower back to 3675 ish.
Running ipmitool sensor output confirms this every...
I've been doing a bit of reading on how to use impitool to adjust the fan thresholds on my motherboard, to prevent the spin up/down issue that some people have previously reported.
The basic steps I took were as per Decrease Supermicro IPMI Fan Threshold
This MB has 5 headers, FAN 1...
Ah, ok, when running from a FreeDOS bootable USB key, sas2flsh can see the controller. Just didn't seem to work when running from within Windows.
Do I need to flash the P20 BIOS before doing the P20 firmware?
Can you confirm commands to run are:
sas2flsh -biosall mptsas.rom
Just got a 480GB Samsung SM953 NVMe SSD, which I wanted to check the firmware version of, and configure over provisioning etc.
Oddly, when I use either the consumer or datacenter versions of Samsung magician, it cannot find the drive.
Has anyone else ever used one of these, and been...
I finally received my new adaptor, which is detected on the two machines I tried it in (Including showing me the oprom).
Problem is, it has P15 firmware on it, but sas2flash doesn't detect the card, nor does megarec.
Any thoughts on how I should go about updating the firmware if the update...
Would it be a command along the lines of:
sensor thresh "CPU Temp" upper 60 80 95
Are those thresholds appropriate or would you lower them further still?
Assume again, that once the first threshold is breached, fans spin up slightly higher, then second threshold they ramp up more and then by...
