How vPars Works

Security
You should be aware of the following security concerns:
• The vPars commands (as described in “Monitor and Shell
Commands” on page 97) are restricted to root access, but the
commands work on any of the virtual partitions, regardless of which
partition the commands are executed from. Therefore, a user on one
partition can affect another virtual partition by targeting the virtual
partition in a vPars command. For example, a root user running on
the partition vpar2 can reset the partition vpar3 using the
vparreset command.
• A user with console access can gain access to the file systems on any
of the virtual partitions in the hard partition. This is done by
performing a hardware reset of the server, interrupting the boot
sequence, and at the ISL prompt manually booting any virtual
partition into single-user mode.
