From the output of command "ls -lrt /dev/oracleasm/disks" we get the major and minor number which can be used to find the physical device corresponding to the asm disk. I include it here just for the sake of completeness. With df, that is possible. Physical volumes are the raw materials or building blocks that are used to achieve the abstraction that is logical volumes. After re-creating the dropped sdc physical volume, we have all we need to create a volume group that can hold a logical volume. By this time you should be able to differentiate between the disk and partitions, i assume. Home » Articles » Linux » Here. To check the attached LUN from a storage device in Linux, we can use the /proc/scsi/scsi file content but it will give you some information and you can not be able to distinguish physical attached drive to LUN. Within the volume groups in Figure 5.1, "Physical Partitioning versus LVM", four logical volumes (LV 1 through LV 4) have been defined, which can be used by the operating system via the associated mount points (MP).The border between different logical volumes need not be aligned .

Directories and Physical Disks Every file in a Linux system is assigned a unique number called an inode . RAID contains a group or a set of Arrays (set of disks). As I mentioned, the physical hard disk is assigned an unique id at startup. This action helps identify the storage device you want to partition. OR. Check Linux Disk Space Using df Command. Linux is typically packaged in a Linux distribution.. The proper way to list block devices such as hard disks is using the command lsblk. The -d or –nodeps will print out the device and not the partitions. This one is similar to previous ones mentioned, it lists all partitions and allows to manage them. blkid will print out several different attributes about the block devices.

Firstly, connect the disk to your Linux system if you haven't already and launch the Terminal window on it. It lists the actual “disk space usage” and it can give you information about what hard disks (or current disk space) is being used in the entire system. From Windows, the disk can be accessed from File Explorer by navigating to: \\wsl$\\<Distro>\\<Mountpoint> (pick any Linux distribution).
