How vPars Works

Security
You should be aware of the following security concerns:
• The vPars commands (as described in “Monitor and ShellCommands”
on page 71) 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 same computer or hardware partition.
This is done by performing a hardware reset of the computer (Ctrl-B),
interrupting the boot sequence, and at the ISL prompt manually
booting any partition into single-user mode.
