Known Problems
Lost Console Input
Description: There is one known case where the virtual console
will ignore keyboard input (data sent to the console continues to
be displayed; only keyboard input is ignored).
The suggested workaround below is only available when at least
one other virtual partition is accessible. Otherwise, you must
reboot the computer in order to regain console input.
Symptoms: The virtual partition that owns the console
hardware port is down, and the CPU with the lowest hardware
path is not assigned to any virtual partition. When this CPU is
migrated to a running virtual partition, the console will not
accept any keyboard input.
Workaround: You can do either of the following to resolve the
problem:
• From a running partition, reset the partition that owns
the hardware console port by executing vparreset -p
target_partition -h, where target_partition is
the partition that owns the hardware console port.
