Increasing the LUN size on a Dell MD3000i storage device (2016184)

Purpose

This article provides information on growing the LUN size on a Dell MD3000i storage device.
 
You may want to increase the LUN size if a virtual machine running on a snapshot/delta file residing on the storage device has run out of space. To be able to power on the virtual machine before the consolidation starts, you must increase the LUN size.

Resolution

You can increase the LUN size in a Dell MD3000i storage device using the SMCli utility.
 
To increase the LUN size:
  1. Open a command prompt.
  2. Navigate to the directory where smcli.exe is installed.
  3. Run this command:

    smcli -n arrayname -c "set virtualdisk [\"virtualdisknametoresize\"] addCapacity=size";

    Where:

    arrayname is the name/IP address of the array
    virtualdisknametoresize is the name of the LUN to grow
    size is the number of bytes to add to the LUN

    For example, to add 136 GB (~ 146028888064 bytes) space to the virtual disk VD_Test in the Array001 array:

    smcli -n Array001 -c "set virtualdisk [\"VD_Test\"] addCapacity=146028888064";
