HP Thunderbolt 2-Port AiO Module ESXi/ESX manual Module parameters, Using module parameters

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
