Savoir si il y a du SAN :

lspci |egrep -i -e "emu|qlo"

Avoir plein d'infos avec dmidecode

#dmidecode  |grep -e "Product" |head -1
dmidecode -s system-product-name

Product Name: PowerEdge R710

dmidecode -t1

cat /proc/bus/input/devices

Quelques commandes utiles :

• dmesg
• lsusb -t, lsusb -v -d 1050:0120
• lspci
• lsscsi -H, lsscsi -g
• lshw
• inxi
• lscpu
• lsblk
• dmseg
• hwinfo --short
• /sbin/discover
• lsdev procinfo (paquet procinfo)
• lsmod
• numactl --hardware

Un lsmod peut également révéler beaucoup d'information sur le matériel

nproc
lscpu
lshw -c cpu
dmidecode -t processor
cpupower monitor

iucode_tool --scan-system
iucode_tool: system has processor(s) with signature 0x000406f1

lsblk
lsblk /dev/sda --bytes --nodeps --pairs --paths --output SIZE,ROTA,RO,TYPE,PKNAME,NAME
 
fdisk -l
parted -l
hdparm -i /dev/sda
 
systemctl list-units --type=device

lshw -c network

Si UNCLAIM apparaît : probablement un problème de driver

lspci |grep -i net

cat /proc/cpuinfo

Hyper-Threading ?
grep -o -w -e '^flags.* ht' /proc/cpuinfo

Si non :

Si oui :
