Assigning the Hardware Console LBA
One of the virtual partitions must own the LBA that contains the physical hardware console port. In our
example server, the hardware console port is at 0/0/4/0, which uses the LBA at 0/0. The LBA 0/0 is owned
by the partition winona1:
CAUTION The A.03.xx releases of vPars require the first virtual partition to own the LBA for the physical
hardware console port. For the example above, when we create the virtual partitions, we would
create winona1 and keira1 first.
CAUTION vPars Console Assignment on sx2000-based Servers
The console UART for sx2000-based servers is no longer on a PCI card, and the system console
is memory mapped and moved to PDH. Hence, there is no LBA component for the console to be
assigned to a virtual partition.
Thus, for sx2000-based servers, you must assign the console by hardware path to a virtual
partition by performing the following steps. For sx2000-based servers running vPars A.03.xx,
the console hardware path must be assigned to the first virtual partition created.
1. Find out the console hardware path:
# ioscan -kfnC tty
Class I H/W Path Driver S/W State H/W Type Description
=============================================================
tty 0 0/8/1 asio0 CLAIMED INTERFACE Built-in RS232C
/dev/diag/mux0 /dev/mux0 /dev/tty0p0
The console hardware path on this system is 0/8/1.
2. Assign the console hardware path to the first virtual partition being created:
# vparcreate -p vPar1 -a io:0/8/1 ...
