won’t boot). The size defined here is fixed at 2000MB. Note that impacts exist later that
prevent you from decreasing the size below approximately 1GB. The reason for the much larger
size is that kernels are considerably larger on HP-UX 11i v3 than previous HP-UX releases.

# Note that for PA-RISC systems /stand must be no larger than

The other logical volumes are controlled by the use model "Create separate volumes
(/usr, /var, ...)". When it is set to true (and it is by default as we saw earlier) other file
systems are created.
"Create separate volumes (/usr, /var, ...)" {
Below is the definition of /usr. Compared to previous releases of HP-UX the definition is simplified,
since the size no longer changes depending on the size of the root disk. We have large files
enabled, and only for the disk layout “Logical Volume Manager (LVM) with HFS” is the
file system type set to HFS.
The size is a minimum of 512MB, and can have a maximum size of the impacts with a minimum of
20% free. It can be resized by Ignite-UX to take into account the remaining space if there is not
enough to meet the maximum size.
The configuration dealing with _hp_root_grp_striped is last, and enables the logical volume
to be striped over all the disks in the root volume or disk group (assuming there is more than one
since it won’t do much if only one disk is present). This configuration is present in other logical
volume definitions and won’t be mentioned again.
