Enable or Disable VAAI
This command turns on or turns off VMware vStorage API Array Architecture (VAAI) for a storage array.
The storage array comes with VAAI turned on. Use this command to turn off VAAI if you do not want to
run VAAI, or if VAAI is causing issues with the storage array. The only storage array that is affected is the
storage array on which the command is run.
Syntax
set storageArray vaaiEnabled=(TRUE | FALSE)
Parameter
Parameter Description
vaaiEnabled
The setting to turn on or turn off VAAI. To turn on
VAAI set this parameter to TRUE. To turn off VAAI
set this parameter to FALSE. The default setting is
that VAAI is turned on.
NOTE: VAAI enables some storage tasks to be offloaded from the server hardware to a storage
array. Offloading the storage tasks to a storage array increases host performance by reducing the
tasks the host must perform.
This command is not supported on the CE4900, CE7900, or the CE7922 storage arrays.
