Module parameters
Using module parameters
The following table describes the module parameters you can set using the
Sample command:
You must reboot the ESX or ESXi system to enforce any parameter changes.
Module parameter | Default (min/max) | Description | |
|
|
|
|
auto_attach | 1 | 1 | = Always attach the device on startup. |
|
| 0 | = Do not attach the device on startup. |
external_power_override* | No devices selected | Allows selected devices to draw full power from | |
|
| the PCIe slot. The <value> for this parameter is | |
|
| a | |
|
| numbers. | |
|
|
|
|
force_minimal_mode | 0 | 1 | = Force minimal mode on the device. |
|
| 0 | = Do not force minimal mode on the device. |
parallel_attach | True | 1 | = Enable parallel attach of multiple drivers. |
|
| 0 | = Disable parallel attach of multiple drives. |
tintr_hw_wait | 0 (0, 255) | Interval (microseconds) to wait between | |
|
| hardware interrupts. Also known as interrupt | |
|
| coalescing. | |
|
| 0 | = Off. |

*Use this parameter with care. For more information, see "Enabling PCIe power override (on page 23)."
Except for the external_power_override parameter, module parameters apply to all IO Accelerator devices in the system.
