HP c-Class Solaris manual Uninstalling IO Accelerator VSL and utilities, Disabling auto attach

Page 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.

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.To set the module parameter, edit the /usr/modprove.d/iomemory-vsl.conffile, 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.
