I recently had to add a new virtualised disk to a VM guest without having to reboot, lucky for me it required a single disk with a single full partition.

This Example

In this example I am attaching a virtual vmdk disk to a virtual machine on VMware ESX. This is the second disk added so for this example it is /dev/sdb but this might be different for your setup if you have more than a few disks. I will also be formatting this disk as EXT3.

Note: You don’t need to install lsscsi but it is useful to see what SCSI devices are attached

  1. Add the disk (either virtually or physically)

Lsscsi to check SCSI disks
