Chapter 3 Maintaining the Server
The override parameter is a setting for the IO Accelerator VSL software by server and is not stored in
Note
the device. When moved to a new server, the device defaults to the 25 W power limit until an external
power cable is added or the override parameter is enabled for that device in the new server.
Step 1 Determine the serial number of the installed Fusion device by using the
Accelerator VSL software. Sample output is shown here:
fio-status
Adapter: Dual Controller Adapter
Fusion-io ioDrive2 3.0TB, Product Number:F01-001-2T41-CS-0001, FIO SN:1149D0969
External Power: NOT connected
PCIe Power limit threshold: 24.75W
Connected ioMemory modules:
fct2: SN:1149D0969-1121
fct3: SN:1149D0969-1111
In this example, 1149D0969 is the adapter serial number. If you have multiple Fusion ioDrive3 devices
installed in your system, use the

For example:
options iomemory-vsl external_power_override=1149D0969,1159E0972
Step 3 Reboot the server or unload and then load the drivers to enforce the parameter changes.
