Module parameters

Using module parameters

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