          You can try using fdisk or partedUtil do see partitions on the disks. The one with ESXi on it should have several partitions.

              Hello,

               

              Kindly find the below, It will be a combination of several commands:

              First find the vmfs path of boot disk:    ls -la /bootbank

              which will give you something like: /bootbank -> /vmfs/volumes/c3fc2b77-b938092d-0a3d-abb9bf510f0f

              Now do find which disk id that is actually using: vmkfstools -P /vmfs/volumes/c3fc2b77-b938092d-0a3d-abb9bf510f0f

              which will give you something like

                  "Partitions spanned (on "disks"):

                          t10.ATA_____WDC_"

              Now you can find the details of the disk with: esxcli storage core device list |grep -A27 ^t10.ATA_____WDC

              which will give you the information you are looking for

                  "t10.ATA_____WDC_WD2500AAKS2D00B3A0________________________WD2DWMAT12492277

                There is maybe more straight forward process but this should work.

                 

                1) ls -la /bootbank

                 

                Should return something like

                lrwxrwxrwx    1 root     root            49 Mar 12 08:27 /bootbank -> /vmfs/volumes/3ca06c7f-b2f44bac-a3b4-aca9a1a6c993

                 

                2) vmkfstools -P /vmfs/volumes/3ca06c7f-b2f44bac-a3b4-aca9a1a6c993

                 

                vfat-0.04 (Raw Major Version: 0) file system spanning 1 partitions.

                File system label (if any):

                Partitions spanned (on "disks"):

                  mpx.vmhba0:C0:T0:L0:5

                Is Native Snapshot Capable: NO

                This is your disk (and 5 is partition)

                 

                3) esxcli storage core device list

                 

                And looks for your disk

                 

                mpx.vmhba0:C0:T0:L0

                You would have different names here - like identification of your RAID volume.

                  Hi,

                  You can do the following to find on which disk is your ESXi installed:

                       1. Run command ls -l /

                       2. You will get the paths to each of the folder under /

                       3. Find bootbank from it:

                            lrwxrwxrwx    1 root     root            49 Mar 28 13:39 bootbank -> /vmfs/volumes/07100d7f-97af111a-ddb3-b5b4282c84a2

                       4. Run command: vmkfstools -Ph /vmfs/volumes/07100d7f-97af111a-ddb3-b5b4282c84a2

                       5. It will list the details where the bootbank has been created. The disk identifier is also listed, something like:

                            Partitions spanned (on "disks"):

                               mpx.vmhba2:C0:T0:L0:5

                   

                   

                  Regards,
