Installing and Managing HP-UX Virtual Partitions (A.02.01)

How vPars Works
Virtual Consoles
Chapter 242
For rp7400/N4000 and rp5470/L3000 servers, the pause can be from
ten to twenty seconds. For Superdome and other nPartition-able
servers, the switchover pause can be minutes, depending on the
amount of memory owned by the virtual partition that owns the
hardware console port.
• Switchover Pause during the Crash State
Whenver the virtual partition that owns the hardware console port is
in the crash state, the switchover pause will occur and remain as
long as the virtual partition is in this crash state. For more
information on the crash state, see the vparstatus (1M) manpage
and “Obtaining Monitor and Hardware Resource Information” on
page 129.
• Toggling Past the Monitor Prompt
When the monarch CPU of the server is not assigned to any
partition, you will see the monitor prompt. Press Ctrl-A to cycle to
the console window of the next partition.
• GSPdiag1 device file
The GSPdiag1 device file (/dev/GSPdiag1) can only be accessed from
the virtual partition that contains the console hardware port.
• Terminal Emulation
To avoid display problems, be sure that the terminal setting of the
GSP on the vPars server matches the terminal or terminal emulator
that you are using to access it. For details on how to do this, see
“Setting the GSP Terminal Type” on page 76.
• Ignored Keyboard Input
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). This occurs when the virtual
partition that owns the hardware console 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.
You can do either of the following to resolve the problem:
