Host Hardware Inventory - Hard Disk Model - M.2 Nvme not identify

[george1421]

@AlexPDX Lets debug this a bit more then. If you have the target computer registered in FOG, then lets setup a debug capture or deploy doesn’t matter. So schedule a deploy task but before you hit the schedule task button tick the debug checkbox.

Now pxe boot the target computer. After a few screens of text that you have to clear with the enter key you will be dropped to the fos linux command prompt.

This next section is optional but will help with debugging so that you can copy and paste info a bit easier., Key in ip a s and get the IP address of the target computer. Next key in passwd and give root a password. Make it something simple like hello, no worries it will be reset when FOS Linux reboots. Now ssh or use putty to connect to the target computer using the IP address, user id of root and password you just set. This remote console will let you copy and paste.

Now key in/paste the following info:
lspci -nn | grep -i sata
lspci -nn | grep -i raid
grep -i firm /var/syslog

Post the results here. The lspci commands will let us see what disk controller is being reported and the last will look to see if there is any missing firmware statements posted by the kernel.

@george1421 Ok , ill do this…sorry for the late reply …i’m actually Help-desk Support in the company i work so yea…a lot of “Hello, IT, have you tried turning it OFF and ON again” …i just love FOG and makes things better 4me

ill be back after the debugging

[AlexPDX]

@Sebastian-Roth Exactly , in the web UI , hosts with SATA SDD’s , are acknowledged …hosts with NVMe SSD > not
The same Motherboard , if i attache SATA SSD and do a HW Inventory, it works fine …but if i attached the NVME M.2 SSD > the Hard Disk is BLANK just like in the attached images

[AlexPDX]

@george1421 ok so i got this :

[Thu Mar 16 root@fogclient ~]# lspci -nn | grep -i sata
00:17.0 SATA controller [0106]: Intel Corporation Device [8086:43d2] (rev 11)
[Thu Mar 16 root@fogclient ~]# lspci -nn | grep -i raid
[Thu Mar 16 root@fogclient ~]#
[Thu Mar 16 root@fogclient ~]# grep -i firm /var/syslog
grep: /var/syslog: No such file or directory

but i did found this “messages” in /var/log of it helps : messeges.txt

[george1421]

@AlexPDX From the log it looks like the nvme is detected. At the fos linux command prompt key in lsblk and post the results. That should show us the block devices (i.e. hard drives attached)

@AlexPDX Is this output from fos linux?

the nbdX devices have me confused.

On the NVMe side we can surely see the nvme disk is there and it has 4 partitions .

Rereading your initial post, is it that FOS isn’t returning the hard disk model name, or it can’t image the computer?

@george1421 From the looks of things and @AlexPDX please keep me honest:

This isn’t a problem from imaging. Simply the HDD information for the inventory isn’t present.

So while sure it’s weird that we can’t detect the drive type for the inventory, it’s not really hurting anything at the present as the Inventory is just an informational thing.

dmidecode (which I believe is what pulls all the inventory data) might just not know how to detect the specific information from that NVME either because the manufacture didn’t fill out the items that dmidecode is looking for, or is using a different language that can’t be utf decoded.

Just my thoughts.

Ultimately, there’s not really a “problem” persay. Just that the inventory can’t pull the information from this NVME device?

(I believe for HDD we use hdparm and all that jazz)

[Tom Elliott]

@Tom-Elliott This is the location of the “get hard disk” elements:

https://github.com/FOGProject/fos/blob/master/Buildroot/board/FOG/FOS/rootfs_overlay/usr/share/fog/lib/funcs.sh#L1405

This is the code that stores the hd returned from above link:
https://github.com/FOGProject/fos/blob/master/Buildroot/board/FOG/FOS/rootfs_overlay/usr/share/fog/lib/funcs.sh#L106

To try to get information from it.

Since nvme0n1 is the drive, you could manually attempt running:
hdparm -i /dev/nvme0n1 to see what returns in the debug prompt?

Pretty sure Tom is right here. Just had a quick look at the scripts and turns out we use hdparm (code ref) which might not be able to grab the information from NVMe disks per se.

You are right. I am wondering if we added this kernel feature when updating to a newer LTS line at some point. I don’t think we need it. Though it’s always good to make sure. So here is the github commit that introduced those features years ago when we moved from 4.5.x to kernel 4.7.x: https://github.com/FOGProject/fos/commit/b56b8d9f6356f6e702e6ff580b2c4500f27ac41f#diff-15f9b0e5270fc1caac75f8b936c3df11534ceeb08de376b7a72b38c75ff2ad1aL1122

@Tom-Elliott Do you remember if this was added for a reason? Not saying this is an issue at all. Just wondering if we might think about removing it to further slim down the kernel binaries?

[Tom Elliott]

@Sebastian-Roth Those are network block devices. I don’t remember exactly why it was added, but it seemed a necessity.

I’ll try to re-review the why.

That’s exactly what my problem is…i have over 300 host managed by FOG …i use a lot of snap-ins, imaging, and specially Hardware Inventory so i know exactly what that host has in order to deploy the MBR or UEFI image, without having to physically travel to that host…only in case of hardware change (RAM, SSD or the whole PC).
And there is also an “internal managing” issue …each PC has an bar code and we do the “handover report” , so, each PC has his own bar code, but some of them are slightly different one from each other, by RAM or SSD or NVME…and i need to know that

Yes, surely we need to use a different command to get that information, e.g. nvme id-ctrl /dev/nvme0n1 | grep mn or smartctl --info /dev/nvme0n1 | grep Model (https://sleeplessbeastie.eu/2022/03/21/how-to-display-information-about-nvme-storage-device/)

https://opensource.com/article/21/9/nvme-cli

May need to see if we have nvme-cli on the FOS systems.

Specifically you would use nvme list /dev/nvme0n1 and should provide details.

Trying to figure out what we’d need.

Maybe something like:

hdinfo=$(hdparm -i $hd 2>/dev/null || nvme id-ctrl $hd | awk  '/mn[ ]+:/ {split($0, model, ": "); modelno = model[2]} /sn[ ]+:/ {split($0, serial, ": "); serialno = serial[2]} /fr[ ]+:/ {split($0, firmware, ": "); fwrev = firmware[2]} END {gsub("^[[:space:]]+|[[:space:]]+$", "", modelno);gsub("^[[:space:]]+|[[:space:]]+$", "", fwrev);gsub("^[[:space:]]+|[[:space:]]+$","",serialno);print "model="modelno",fwrev="fwrev",serialno="serialno}')

[Tom Elliott]

@Tom-Elliott said in Host Hardware Inventory - Hard Disk Model - M.2 Nvme not identify:

nvme list $hd | tail -1 | awk -F" {2,}" ‘{print “model=”$4",fwrev=“$8”,serialno="$NF}’

@AlexPDX Can you try running the command:

nvme list /dev/nvme0n1 | tail -1 | awk -F" {2,}" '{print "model="$4",fwrev="$8",serialno="$NF}'

[AlexPDX]

@Sebastian-Roth said in Host Hardware Inventory - Hard Disk Model - M.2 Nvme not identify:

nvme id-ctrl /dev/nvme0n1 | grep mn

This one worked
[Thu Mar 16 root@fogclient /]# nvme id-ctrl /dev/nvme0n1 | grep mn
mn : KINGSTON SNV2S250G
mntmt : 273
mnan : 0

nvme list /dev/nvme0n1 | tail -1 | awk -F" {2,}" ‘{print “model=”$4",fwrev=“$8”,serialno="$NF}’

this returned :
model=1,fwrev=512,serialno=ELFK0S.4

And :

smartctl --info /dev/nvme0n1 | grep Model
returned:
Model Number: KINGSTON SNV2S250G

[Sebastian Roth]

@AlexPDX @george1421 @Tom-Elliott Great we got this figured out. Please let us discuss the details on github: https://github.com/FOGProject/fos/issues/72

[Tom Elliott]

@AlexPDX can you try:

nvme id-ctrl /dev/nvme0n1 | awk  '/mn[ ]+:/ {split($0, model, ": "); modelno = model[2]} /sn[ ]+:/ {split($0, serial, ": "); serialno = serial[2]} /fr[ ]+:/ {split($0, firmware, ": "); fwrev = firmware[2]} END {gsub("^[[:space:]]+|[[:space:]]+$", "", modelno);gsub("^[[:space:]]+|[[:space:]]+$", "", fwrev);gsub("^[[:space:]]+|[[:space:]]+$","",serialno);print "modelno="modelno",fwrev="fwrev",serialno="serialno}'
