On modern udev installations,here are symbolic links to storage media in subdirectories of
[sankar@new-host ~]$ cd /dev/disk
[sankar@new-host disk]$ ls
by-id
by-label
by-path
by-uuid
[sankar@new-host disk]$
/dev/disk
, that let you look up a disk or a partition by serial number (/dev/disk/by-id/
), by UUID (/dev/disk/by-uuid
), by filesystem label (/dev/disk/by-label/
) or by hardware connectivity (/dev/disk/by-path/
).[sankar@new-host ~]$ cd /dev/disk
[sankar@new-host disk]$ ls
by-id
by-label
by-path
by-uuid
[sankar@new-host disk]$
Under Linux 2.6, each disk and disk-like device has an entry undr
/sys/block
.
disks and partitions are listed in
/proc/partitions
.
Alternatively, you can use lshw:
lshw -class disk
.(lshw - list hardware)lshw -class disk -class storage
command . it will show detailed information on disk configuration. you will get the vendor,type of disk etc all information.cat /proc/scsi/scsi
and parted --list
shows the RAID controller.# lshw -class disk
*-disk
