11.1 Linux To check or verify if the OSS devices are detected, type or enter the command “lspci -vvv |grep c030”, see output below. • It will show 46 total number of c030 device IDs, combining both OSS_579 adapter cards and the OSS_581 board. - Page 22 This is the single OSS_579 host card displaying 13 of c030 device IDs. To check on the OSS-581 device hierarchy type or enter the command on a terminal window “lspci -vvtt”. The screenshot below shows the hierarchy (tree-like structure) of the OSS_581 backplane without PCIe cards in the slots.
