System Administration Commands sysadm(8)
NAME
sysadm - maintain host
SYNOPSIS
sysadm maintain -s [ -m "message" ]
sysadm maintain -l [-p] [-o field1,...]
sysadm maintain -e
sysadm evacuate [-arnvqw]
sysadm evacuate -l [-p] [-o field1,...]
DESCRIPTION
The sysadm utility is used to control maintenance mode for a system and
perform evacuation of zones hosted on the system.
Only users and roles that belong to the "Maintenance and Repair" RBAC
profile can use the sysadm command.
Starting a maintenance mode will log an audit record and prevent the
subsequent attach, boot, or incoming migration of any zones into the
system. This can be used to perform administration on a zones host and
remove it from service.
Maintenance state is held across host reboots and changes between dif‐
ferent boot environments.
To bring zones back into service, maintenance must be ended with the -e
option.
Optionally, the host may be evacuated by migrating all solaris-kz,
solaris and solaris10 brand zones away from the system. A non-interac‐
tive RAD URI of the destination zones host must be given in the evacua‐
tion/target property of the zone instance. A default destination host
may also be specified on the zone service svc:/system/zones/zone.
SUB-COMMANDS
The following subcommands are supported:
sysadm maintain -s [ -m "message" ]
Starts maintenance. An optional free-form message string may be
given.
Starting maintenance clears any existing evacuation state.
sysadm maintain -l [-p] [-o field1,...]
Lists maintenance state if any.
-o field[,...], --output=field[,...]
A case-insensitive, comma-separated list of output fields to
display. The field name must be one of the fields listed below,
or the special value all to display all fields.
TYPE The type of maintenance. Currently, always the value
admin.
USER The user who sets the maintenance mode.
DATE The date when the maintenance mode is set.
MESSAGE Any message associated with the maintenance mode.
-p
Displays using a stable machine-parseable format. The -o option
is required with the -p option.
sysadm maintain -e
Ends maintenance mode.
sysadm evacuate -l [-p] [-o field1,...]
Lists any evacuation state. After a partial evacuation, this may
show zones evacuated to destination systems, as well as zones that
failed to evacuate, along with the reason for the failure.
-o field[,...], --output=field[,...]
A case-insensitive, comma-separated list of output fields to
display. The field name must be one of the fields listed below,
or the special value all to display all fields.
ZONENAME Name of the zone.
STATE The state of evacuation for the zone. If EVACUATED,
then the zone is evacuated to the location speci‐
fied by the DEST value. If SKIPPED, then the evacu‐
ation is not attempted, and the zone may still be
running. If FAILED, then the evacuation failed, and
the ERROR field will give more information.
DEST The destination RAD URI that the zone is evacuated
to, or the last attempted destination if FAILED.
ERROR If the state is either SKIPPED or FAILED, then this
gives the relevant error status.
-p
Displays using a stable machine-parseable format. The -o option
is required with the -p option.
sysadm evacuate [-arnvq]
Evacuates the host system. Or, with the -r option, returns zones to
the host.
For each running zone, evacuation live migrates the zone to the
destination configured in its SMF service instance.
If an individual zone is of a brand that does not support live
migration, then evacuation is skipped and the state for that zone
will be SKIPPED.
If the -a option is specified, then non-running zones are also
evacuated by using cold migration.
If an individual zone fails to evacuate, then the state for that
zone will be FAILED, and the ERROR value will be filled in with
more information.
-a Evacuates both non-running zones as well as running
zones.
-v [-v] Reports evacuation progress verbosely to the standard
output. Each output line has a timestamp.
When the -v option is doubled, the detailed per zone
migration progress is reported too.
-q Only reports errors.
-n Dry-run evacuation. Migration is planned, and a dry-run
migration to the destination host is performed for each
zone.
-r Returns zones. Each evacuated zone is migrated from its
destination, if it is still running there, back to the
source host. If the -a option is specified, it is cold
migrated back if not running.
-w Overwrite zone configuration for each evacuated zone on
the destination host with the respective configurations
from the source host. This is mutually exclusive with
the -n option.
Evacuation may be run several times, in case some zones fail to evacu‐
ate on the first run. The return status is successful only if the evac‐
uation as a whole is complete. This means that there should be no zones
running on the relevant hosts after executing the sysadm command.

EXIT STATUS
The following exit values are returned:
0 Successful completion.
For evacuation, this exit value means that no zones are still run‐
ning on the source system. For evacuation return, this exit value
means that all zones have been migrated back to the source system.
1 An error occurred.
CAVEATS
When SSH transport is used, the sysadm utility requires the SSH keys to
have empty passphrase to ensure non-interactive evacuation of the zones
and their eventual returning. Unlike zoneadm(8), the sysadm utility
ignores the SSH_AUTH_SOCK environment variable.
