• System-wide stable storage and the setboot command
On a non-vPars computer, the setboot command allows you to read
from and write to the system-wide stable storage of non-volatile
memory. However, on a vPars computer, the setboot command does
not affect the stable storage. Instead, it reads from and writes to only
the partition database.
For more information see “System-wide Stable Storage and Setboot”
on page 42.
• mkboot and LIF files
The mkboot command allows you to write to files in the LIF area, for
example, the AUTO file. While on a vPars computer, mkboot can still be
used to write to files in the LIF area, the LIF area is not read during
the boot of the OS of a virtual partition. Instead, only the information
stored in the vPars partition database is read. (Note: the files in the
LIF area are still read when the entire computer boots).
To simulate the effect of an AUTO file for a virtual partition, use the
vPars commands so that the information is saved in the vPars
partition database. For more information, see “Simulating the AUTO
File on a Partition” on page 104.
• shutdown and reboot commands
In a virtual partition, the shutdown and reboot commands shutdown
and reboot a virtual partition and not the entire computer.
To ensure the vPars database is synchronized before a shutdown or
reboot of a partition, run vparstatus before the shutdown or reboot
command.
Also, if a partition is not set for autoboot, the shutdown -r or reboot
-r commands will only shut down the partition; the partition will not
reboot. In other words, the partition will halt.
For more information, see “Shutting Down or Rebooting a Partition”
on page 90 and “Shutting Down or Rebooting the Computer” on page
91.
• /stand file system size
Due to the vPars files that will exist in /stand, you should increase
by 50 MB the size of the /stand file system that you normally create.
