HP IO manual Fio-config /dev/fctx -p PCIeGLOBALSLOTPOWERLIMIT

fct2: SN:1149D0969-1121

fct3: SN:1149D0969-1111

In this example, 1149D0969 is the adapter serial number.

If you have multiple IO Accelerator devices installed on your system, use the fio-beacon command to verify where each device is physically located.

oInspect the adapter serial number labels on the IO Accelerator devices to determine the serial numbers. However, HP recommends confirming that each serial number is an adapter serial number by running the fio-status command. The adapter serial number label resides on the back of all HP ioDrive Duo devices and HP ioDrive2 Duo devices. On ioDrive Duos, the serial number is located on the PCB component that is attached to the PCIe connector.

2.Set the module parameter for the fio-configcommand-line utility. For example: fio-config-p FIO_EXTERNAL_POWER_OVERRIDE <value>

Where the <value> for this parameter is a comma-separated list of adapter serial numbers. For example:

1149D0969,1159E0972,24589

The -p option makes the parameter persistent after reboot.

fio-config /dev/fct<x> -p PCIe_GLOBAL_SLOT_POWER_LIMIT 74750

Where <x> is the device number for the device relative to the <value> specified adapter serial number. For example:

fio-config /dev/fct2 –p PCIe_GLOBAL_SLOT_POWER_LIMIT 74760

3.To enforce any parameter changes, you must reboot or unload and then load the drivers.
