The first one - Pnn appended - is surely caused by that z/VM 5.4 supports
the newer OSA flavors that have more than one port. HELP DEFINE VSWICTH
tells you the following:
*
RDEV
nnnn
RDEV
nnnn.Pnn
is a real device number or a real device number and OSA Express
port
number to be used to connect the virtual switch to a QDIO OSA
Express
device. Specify each real device number as a 1- to 4-digit
hexadecimal
number. If specifying a real device and an OSA-Express port
number,
specify the real device number as a 1- to 4-digit hexadecimal
number
followed by a period (.), the lettter 'P' (or 'p') followed by the
port
number as a 1- to 2-digit hexadecimal number. For example, to specify
port
1 for RDEV 300, specify "300.P1." The value of the port number depends
on
how many ports the OSA-Express hardware feature supports. If the
port
number is note specified, it will default to port
0. *
Your second question: it shouldn't matter which of the two TCP/IP stacks
gets the role of VSWITCH controller. It probably depends on which the the
two is ready first. If you don't like this randomness, try including a CP
SLEEP 1 SEC in the PROFILE EXEC of AUTOLOG1 (or AUTOLOG2 if you have RACF)
between the XAUTOLOG of DTCVSW1 and 2
