For automation, I use vim-cmd utility to add existing devices as hot add into VMs.
Before running below command there are disks attached to ScsiController 0 with unit id 1,2,3,4,5,6 and when i try to add a next device for Scsi controller 1 with unit id 1 it fails,
Cmd - vim-cmd vmsvc/device.diskaddexisting 3 /vmfs/volumes/esx_ld7/esx_ld7_1527840895.vmdk scsi1 1
Failed: Reconfigure failed
When I started looking for exact issue as per the hostd.log,

Surprisingly,
When I ran below command it passed and added the disk against SCSI controller 0, not 1
vim-cmd vmsvc/device.diskaddexisting 3 /vmfs/volumes/esx_ld7/esx_ld7_1527840895.vmdk scsi1 8
As per .vmx file entries are,
scsi0:8.deviceType = "scsi-hardDisk"
scsi0:8.fileName = "/vmfs/volumes/5b10f551-104555a6-b83b-98f2b3f236a6/esx_ld7_1527840895.vmdk"
scsi0:8.present = "TRUE"
scsi0:8.redo = ""
Can anyone please guide me here, there seems to be some issue.
