Is it possible to issue MPI2_TOOLBOX_BEACON_TOOL messages from userspace (doing ioctl() on /dev/mpt3ctl, using sysfs entry, whatever)? I would like to use this feature to control device LED lights, in the way similar to LSI's (well, Broadcom's) proprietary 'lsiutil' tool. As listed by 'lshw', my device is: description: Serial Attached SCSI controller product: SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] vendor: LSI Logic / Symbios Logic physical id: 0 bus info: pci@0000:03:00.0 logical name: scsi0 version: 03 width: 64 bits clock: 33MHz capabilities: storage pm pciexpress vpd msi msix bus_master cap_list rom configuration: driver=mpt3sas latency=0 resources: irq:29 ioport:7000(size=256) memory:904c0000-904c3fff memory:90080000-900bffff \ memory:90000000-9007ffff memory:904c4000-90503fff memory:900c0000-904bffff Thanks, Dmitry
