Attaching multiple LUNs to a Windows host and later trying to figure out which LUN is which can be a drag. I found out that using the “details disk” command in diskpart can help you finding backup the right LUN:
diskpart
list disk
select disk 19 (or whatever drive you want to see the details of)
detail disk
HITACHI DF600F Multi-Path Disk Device
Disk ID: 00000000
Type : FIBRE
Status : Online
Path : 0
Target : 2
LUN ID : 7
Location Path : UNAVAILABLE
Current Read-only State : Yes
Read-only : Yes
Boot Disk : No
Pagefile Disk : No
Hibernation File Disk : No
Crashdump Disk : No
Clustered Disk : No
There are no volumes.
So in this particular case the Host LUN id was 7. This should help you along a bit 🙂
