Run level process when Physical server goes down
Need inputs when physical server is coming down (ex- init 0) .
We have a physical server in that there are couple of LDOM's and in LDOM's there are couple of Zones . In zones there are applications running .
Physical Server (T4 Server) -> LDOM -> ZONES -> applications
There are scripts that has stop/start applications in zones when zones get rebooted .
So in the main Physical server when you use init 0 command . Does it bring down zones first and then LDOM's . What is the process . Please advice.

ZPRINT(1) General Commands Manual ZPRINT(1)
NAME
zprint - show information about kernel zones
SYNOPSIS
zprint [-w] [-s] [-c] [-h] [-t] [-d] [-p <pid>][name]
DESCRIPTION
zprint(1) displays data about Mach zones. By default, zprint will print out information about all Mach zones. If the optional name is
specified, zprint will print information about each zone for which name is a substring of the zone's name.
zprint interprets the following options:
-c (Default) zprint prints zone info in columns. Long zone names are truncated with '$', and spaces are replaced with '.', to allow
for sorting by column. Pageable and collectible zones are shown with 'P' and 'C' on the far right. Zones with preposterously large
maximum sizes are shown with '----' in the max size and max num elts fields.
-h (Default) Shows headings for the columns printed with the -c option. It may be useful to override this option when sorting by col-
umn.
-s zprint sorts the zones, showing the zone wasting the most memory first.
-w For each zone, zprint calculates how much space is allocated but not currently in use, the space wasted by the zone.
-t For each zone, zprint calculates the total size of allocations from the zone over the life of the zone.
-d Display deltas over time, showing any zones that have achieved a new maximum current allocation size during the interval. If the
total allocation sizes are being displayed for the zones in question, it will also display the deltas if the total allocations have
doubled. -p <pid> Display zone usage related to the specified process id. Each zone will display standard columns and the amount
of memory from that zone associated with a given process. The letter "A" in the flags column indicates that this total is being
accounted to the process. Otherwise, the total is an indication of the influence the process has on the kernel, but the memory is
being accounted to the kernel proper.
Any option (including default options) can be overridden by specifying the option in upper-case; for example, -C overrides the (default)
option -c.
