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

       Display Name: Local ATA Disk (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):

Mode: private

Capacity 261853184 (63929 file blocks * 4096), 107102208 (26148 blocks) avail, max supported file size 0

UUID: 3ca06c7f-b2f44bac-a3b4-aca9a1a6c993

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

   Display Name: Local VMware, Disk (mpx.vmhba0:C0:T0:L0)

   Has Settable Display Name: false

   Size: 10240

   Device Type: Direct-Access

   Multipath Plugin: NMP

   Devfs Path: /vmfs/devices/disks/mpx.vmhba0:C0:T0:L0

   Vendor: VMware,

   Model: VMware Virtual S

   Revision: 1.0

   SCSI Level: 2

   Is Pseudo: false

   Status: on

   Is RDM Capable: false

   Is Local: true

   Is Removable: false

   Is SSD: false

   Is VVOL PE: false

   Is Offline: false

   Is Perennially Reserved: false

   Queue Full Sample Size: 0

   Queue Full Threshold: 0

   Thin Provisioning Status: unknown

   Attached Filters:

   VAAI Status: unsupported

   Other UIDs: vml.0000000000766d686261303a303a30

   Is Shared Clusterwide: false

   Is Local SAS Device: false

   Is SAS: false

   Is USB: false

   Is Boot USB Device: false

  Is Boot Device: true

   Device Max Queue Depth: 1024

   No of outstanding IOs with competing worlds: 32

   Drive Type: unknown

   RAID Level: unknown

   Number of Physical Drives: unknown

   Protection Enabled: false

   PI Activated: false

   PI Type: 0

   PI Protection Mask: NO PROTECTION

   Supported Guard Types: NO GUARD SUPPORT

   DIX Enabled: false

   DIX Guard Type: NO GUARD SUPPORT

   Emulated DIX/DIF Enabled: false

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
