As far as I know it is still important that you don't have duplicate SSIDs.
It still shows up in z/VM displays and z/OS displays. You can still do
commands in both z/VM and z/OS using the SSID. I always assign the SSID to
match the CUNUMBR. We always have the CUNUMBR match the first device address
under the control unit. This way the CUNUMBR is 7000 the SSID is 7000 and the
first device is 7000.
CNTLUNIT CUNUMBR=7000,PATH=((CSS(0),10,30,12,4C,14,22)),
UNITADD=((00,256)),LINK=((CSS(0),0C,14,08,14,04,04)),
...
...
IODEVICE ADDRESS=(7000,224),UNITADD=00,CUNUMBR=(7000),STADET=Y
,UNIT=3390B
IODEVICE ADDRESS=(70E0,32),UNITADD=E0,CUNUMBR=(7000),STADET=Y,
UNIT=3390A

Subject: SSIDs anymore?
Subsystem IDs....
I know you still have to define them in the controllers, but are they used
anymore?
We use to need them for EREP, but all the current hardware seems to have their
own service processor that makes EREP useless.
Perhaps large shops still need them for something.
What happens now, if you have two controllers with the same SSIDs?
Obviously, one of the clients is installing a controller this weekend. Hence
the subject came up.
Thanks
