Automatically attached SCSI devices

Red Hat Enterprise Linux 8.6 LPAR mode z/VM guest

FCP devices that use NPIV mode detect the LUNs automatically and no configuring is necessary.

In this case, no FCP LUN entries are created under /sys/bus/ccw/drivers/zfcp/<device_bus_id>/<wwpn>.

What to do next

To check whether a SCSI device is registered, check for a directory with the name of the LUN in /sys/bus/scsi/devices. If there is no SCSI device for this LUN, the LUN is not valid in the storage system, or the FCP device is offline in Linux®.
