Hot-Add - directly attached devices

New in version 5.11.

Scanning for devices

Initially, devices behind an NTB must be discovered by issuing a scan command with smartio_tool. This command requires that a nodeid is given. This nodeid must be different from the host’s nodeid:

# smartio_tool scan 32
# smartio_tool list
200100: PCI bridge PMC-Sierra Inc. Device 8532 [borrowed by: ] [local users: 0]
200200: PCI bridge PMC-Sierra Inc. Device 8532 [borrowed by: ] [local users: 0]
200300: Non-Volatile memory controller: Intel Corporation SSD [borrowed by: ] [local users: 0]

After the scan, the devices are available for borrowing:

# smartio_tool borrow 200300
Name: Non-Volatile memory controller: Intel Corporation SSD 600P Series
