Open SSH ESXi Session 

Execute this command:  ls -l /  where the output:

Use your ID Disk with this command:

 vmkfstools -P /vmfs/volumes/d408f6e7-974ffb48-05bd-73467ca990f1

The output is similar at this if use USB for boot:

For the last check use command esxcfg-mpath -b for identity the USB disk:

 

If after the command vmkfstools -P ........  the output is similar at this:

the boot is from SAN

+when i try "vmkfstools" it show to me:
vfat-0.04 (Raw Major Version: 0) file system spanning 1 partitions.

UUID: 8480de70-515bb983-35dc-e7b395edbbdd
Partitions spanned (on "disks"):
naa.600508b1001cc37162a8b866dafc2547:5
Is Native Snapshot Capable: NO

+but when try "esxcfg-mpath -b" show to me:
naa.600508b1001cc37162a8b866dafc2547 : Local HP Disk (naa.600508b1001cc37162a8b866dafc2547)
vmhba0:C0:T0:L1 LUN:1 state:active sas Adapter: 5001438022c06aa0 Target: 1438022c06aa0

From first command show to me as SAN because show "nna.." but the second command show to me "local disk"?

Ciao 

Last command esxcfg-scsidevs -a and post the output. 

Do you have ISCSI, DAC or Fibre connection to external disk?

 

[faziz]

we have local disk on server, and we have FC for SAN

VMHBA0 is the local Controller  (Smart Array P220ì) 

My example does not display naa.xxxxxxxxx  because it is a boot from a USB disk.
