System Administration Commands svc.zones(8)
NAME
svc.zones - Solaris Management Facility delegated restarter for
zones(7)
SYNOPSIS
/usr/lib/zones/svc.zones
svc:/system/zones:default
DESCRIPTION
svc.zones is the Service Management Facility (SMF) delegated restarter
for zones(7). Each zone is represented by an instance of the zone ser‐
vice:
svc:/system/zones/zone
The instance name matches the zonename.
The zones delegated restarter sets up the infrastructure for zones(7)
to work. The failures and activity from setting up zones infrastructure
will be logged at:
/var/log/zones/<zonename>.messages
Failures during the infrastructure setup of a particular zone, will
place that zone in maintenance. The zones delegated restarter will
retry the infrastructure setup on svcadm(8) clear for zones in mainte‐
nance because of failures in its infrastructure setup.
The zones delegated restarter performs autobooting of zones at start
time according to each zone's autoboot property setting. For more
information, see the zones(7) and zonecfg(8) manual pages. Likewise,
during a graceful shutdown of the global zone, the zones delegated
restarter service shuts down, halts, or suspends each zone, depending
on its autoshutdown property. For more information, see the zonecfg(8)
manual page.
The zones autoboot and shutdown are performed in parallel, and the num‐
ber of concurrent operations can be limited. For more information, see
the "Zones Delegated Restarter Properties" below.
Zone SMF Dependencies
The set of SMF FMRIs that constitute the zone dependencies will be
defined by a new zonecfg(8) resource dependency. It is comprised of
grouping properties and FMRI properties. All SMF dependencies for a
zone will be of type service, and have restart_on attribute as none.
The following zonecfg(8) commands creates SMF dependencies:
add smf-dependency
set name=firewall
set fmri=svc:/system/zones/zone:appfirewall
set grouping=require_any
end
add smf-dependency
set name=firewall
set fmri=svc:/3rdparty/my-firewall:default
end
add smf-dependency
set fmri=svc:/system/zones/zone:dataload
set grouping=exclude_all
end
The default for grouping is require_all and must not be explicitly set.
The FMRI values will be validated against libscf(3LIB) SCF_TYPE_FMRI.
Zones Boot Ordering
There are two ways to establish the zone's boot order:
1. Determining the SMF dependencies of a zone SMF instance.
2. Assigning boot priority of each zone.
Once the SMF dependencies are satisfied for a zone, that zone is placed
in a queue according to its priority. To assign a boot priority for a
zone, use the zonecfg boot-priority property. For more information on
boot-priority property, see the zonecfg(8) manual page. The zones
restarter will boot the zones from high to low boot priority in the
queue.
Note that the boot ordering based on assigned boot priority is best-
effort and thus non-deterministic. It is not guaranteed that all zones
with higher boot priority will be booted before all zones with lower
boot priority. If your configuration requires a deterministic behavior,
use SMF dependencies.
Zones Delegated Restarter Properties
config/track-zone-goals
This boolean property tells the zones restarter when should a zone
SMF instance be placed in the online state. If set to false, the
zones restarter will place a zone SMF instance in the online state,
immediately when the zone begins to boot up. When set to true, the
online state of a zone SMF instance will be considered according to
the online state description in the "Service States" section. The
default value of this property is true.
config/concurrent-boot-shutdown
The maximum number of concurrent zones booting up or shutting down.
config/concurrent-suspend-resume
The maximum number of concurrent zones performing suspend or resume
operations.
options/logging
The level of logging performed by the zones restarter.
The valid values are:
quiet Minimal logging is performed and only errors are
reported.
verbose Verbose logging is performed.
debug Debug logging is performed.
The following example shows how to set one of the above properties:
# svccfg -s svc:/system/zones:default setprop \
config/concurrent-boot-shutdown = 10
# svcadm refresh svc:/system/zones:default
The Zones Restarter will not limit the number of concurrent operations
if the property has no value, or if the property is absent.
The booting process of a non-global zone will be considered complete
when the zone SMF instance reaches the online state or the maintenance
state. Please see the "Service States" section below for details on the
semantics of the SMF states for zones.
Zone Commands Interaction with the Zones Delegated Restarter
zoneadm(8) commands can override the zones delegated restarter and SMF
graph engine.
A zone can be booted by an administrator even if its SMF dependencies
have not been satisfied. In this case, the zone SMF instance will be
placed in the online or maintenance states, according to the semantics
described in the "Service States" section below. Note that since all
zone SMF dependencies have the restart_on attribute as none, the graph
engine will not send a stop event to the zone SMF instance if the SMF
dependencies for that zone are not satisfied before its boot.
Disabling a zone SMF instance that is in maintenance state because the
zone is in an unbootable state, will not clear the SMF maintenance
state. Disabling a zone SMF instance will only clear a maintenance
state caused by the zone's milestone/goals dependencies requiring
administrative action to be satisfied. In this case, disabling the zone
SMF instance will shutdown the zone.
The zones boot priority and concurrent threshold only apply to opera‐
tions caused by the SMF graph engine events. Administrator commands are
not subject to boot priority or concurrent threshold. This way, if a
zone is assigned a low priority, the administrator can boot it up manu‐
ally without waiting for the many zones with higher priority to boot
up.
Service States
As part of its service management duties, the svc.zones implements a
state machine for each of its managed zone SMF instance. The states in
this machine are made up of the smf(7) set of states. The semantics of
these states are as follows:
uninitialized svc.zones is yet to process this instance.
online The zone is running and has reached the mile‐
stone/goals. For zones that do not support mile‐
stone/goals, the online state will be reached immedi‐
ately when the zone begins to boot. For more informa‐
tion on milestone/goals, see the smf(7) manual page.
degraded The zone SMF instance has reached the online state,
but zoneadmd(8) has failed multiple times and is not
running.
offline The zone SMF instance is enabled, but its SMF depen‐
dencies have not been satisfied.
disabled The zone is halted and will not be booted up by the
zones delegated restarter.
maintenance A zone SMF instance can be in this state because of
the following reasons:
o Failed boot attempt
o The zone is in a state from which it cannot
be booted
o The zone's milestone/goals dependencies
cannot be satisfied without administrative
action.
The output of svcs -vx command should be used to
determine the reason for the maintenance state. A zone
SMF instance in maintenance will not clear the mainte‐
nance state on a disabled event.
