Enable or disable VAAI

The set storageArray vaaiEnabled command turns on or turns off VMware vStorage API Array Architecture (VAAI) for a storage array.

Supported Arrays

This command applies to any individual storage array, including the E2700, E5600, E2800, E5700, EF600 and EF300 arrays, as long as all SMcli packages are installed.

Roles

To execute this command on an E2800, E5700, EF600, or EF300 storage array, you must have the Storage Admin role.

Context

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.

Notes

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.
Note: View the VAAI setting using the show storageArray odxSetting name.
