- What is the difference between LVM and LUN - Server Fault
A LUN is generally a disk array level reference to an amount of raw disk space that's been formatted and allocated to a specific server or group of servers It might be spread out over multiple physical disks, but will be presented by the disk array as a single "logical" drive to the target server LVM stands for "Logical Volume Manager", and is generally a piece of operating system software

The three values stand for channel, SCSI target ID, and LUN The dashes act as wildcards meaning "rescan everything" A quick google search turns up this RHEL doc (and dozens of other answers) This is the same command described in Section 7, “Adding a Storage Device or Path” to add a storage device or path In this case, however, the channel number, SCSI target ID, and LUN values are
- How to get drive letter attached to a data disk in Azure?
Hello @KrishnaChaitanya67, I think the only possible way to get a map between the logical drive and data disk to to get the LUN id for that disk so you can get the lun id in log analytics for the disk drive name as its the perf metrics which is running inside the VM and similarly you can get the LUN id with the data disk name using the python sdk as the details here are provided by Azure
