SAN Attached and VMWare Raw Mapped

1. Resize the LUN on the storage subsystem

   # pvresize /dev/<block_device>

VMWare VMDK

2. Rescan the the SCSI block device

   # echo 1 > /sys/block/<block_device>/device/rescan

3. Update partition size
4. Load the partition into the kernel

   # partprobe /dev/<device>

5. Scan for physical volumes

   # pvscan

6. Resize the physical volume

   # pvresize /dev/<block_device>

7. Verify the resize was successful

   # pvs
