Dear all
Hi
i have 3 disk on my server and 2 of my disks are raid 1+0 but one of them is just raid0 now how can understand esxi has been installed on which disk ?
BR
You can try using fdisk or partedUtil do see partitions on the disks. The one with ESXi on it should have several partitions.
can you exactly say what command do i have to use
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

This is your disk (and 5 is partition)
3) esxcli storage core device list
And looks for your disk

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
