Thanks for the confirmation. In our other frame with drives, there is an
Ethernet cable going to a switch besides the TS3000 console. It has a 172
address (we don't use it), so it must be the call home/maintenance
connection.
FWIW, on Linux systems, the drives used for the control paths appear via
IBMchangern, where the number on entries depends on how many fibre paths
and drives assigned as control paths.
