Mapping physical disk to Vmware EXSi Server


  1. ssh to EXSi server.
  2. ls -al /dev/disks to get the disk label, for my case is 't10.ATA_____WDC_WD20EARX2D00PASB0_________________________WD2DWCAZAE967686', WD 2TB green.
  3. cd /vmfs/volumes, now creating RDM using vmkfstools.
  4. e.g vmkfstools -z /vmfs/devices/disks/t10.ATA_____WDC_WD20EARX2D00PASB0_________________________WD2DWCAZAE967686 /vmfs/volumes/WD0/rdm_WDC_WD20EARX2D00PASB0.vmdk
Now should be able to add the disk to VM.
