HP IO Accelerator for BladeSystem c-Class - Manual (Page 16)

Maintenance 16
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 IO Accelerator devices installed on your system, use the fio-beacon command
to verify where each device is physically located.
o Inspect 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. To set the module parameter, edit the /usr/modprove.d/iomemory-vsl.conf file, and then
change the value for the external_power_override parameter. For example:
options iomemory-vsl external_power_override=<value>
Where the <value> for this parameter is a comma-separated list of adapter serial numbers. For
example:
1149D0969,1159E0972,24589
3. To enforce any parameter changes, you must reboot or unload and then load the drivers.
Uninstalling IO Accelerator VSL and utilities
To uninstall the IO Accelerator VSL and utilities, run the following command:
$ pfexec pkgrm iomemory-vsl
Disabling auto attach
When the IO Accelerator driver is installed, it is configured to attach any devices automatically when the
driver is loaded. When necessary, disable the auto-attach feature.
To disable auto attach:
1. Edit the following file:
/usr/kernel/drv/iomemory-vsl.conf
2. Add the following line to that file:
auto_attach=0;
3. Save the file.
To re-enable auto-attach, edit the file, and then either remove that line or change it to:
auto_attach=1;
Unmanaged shutdown issues
If you experience an unmanaged shutdown, then the IO Accelerator performs a consistency check during the
reboot. The reboot might take several minutes or more to complete and is indicated by a progress percentage
during the startup.
