Volume Autosizing !!!

Requirements of the customer.

• Create a volume, such that maximum utilization should not exceed 600gb.
  
• Initial storage assigned should be 400gb, which should increase gradually when it nears the limit. (max size is 600gb).
  

Because customer doesn't want the end users to use up space more rapidly.

Solution :

• Created a volume of 400gb, set the auto sizing on for that volume. It has to grow by 20gb when it nears the limit up to a maximum of 600gb

Syntax:

vol autosize volname -m 600g -i 20g on

@ By default autosize on a volume is disabled. The "on" subcommand is used to enable the auto size. (Remember 600gb included the snapshots area as well). Plan the max spacing accordingly.
