Module parameters

Using module parameters

The following table describes the module parameters you can set using the esxcfg-module command.

The remote option (--server) is only required for the vCLI.

Sample command:

esxcfg-module --server <server-name> iomemory-vsl -s '<parameter>=<value>'

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 comma-separated list of adapter serial

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.

To query the current module parameters, use the following command:

esxcfg-module --server <server-name> iomemory-vsl -g
