===== Common Tasks =====

==== Common Admin Tasks ====
=== Services ===
  * Check the dependents of the service: ''svcs -D //servicename//''
  * Enable a service:  ''svcadm enable //servicename//''
  * Enable dependencies of a service:  ''svcadm enable -r //servicename//''
  * Verify a service has been enabled: ''svcs -x //servicename//''
  * Restart a service:  ''svcadm restart //servicename//''
  * Enable a service temporarily (or in single-user mode):  ''svcadm enable -rt //servicename//'' \\ // This will enable service with its dependencies for current session, not persisted across reboots //
  * Disable a service:  ''svcadm disable //servicename//''

=== Services in maintenance state ===
Normally, when a service instance is in a maintenance state, all processes associated with that instance have stopped. However, you should make sure before you proceed.

Determine why the service is in maintenance:  ''svcs -x //servicename//''
  * Consult the log file or man page mentioned to determine what the error is.
  * Determine if any process that are dependent to the service have not stopped.

The following command lists all of the processes that are associated with a service instance as well as the PIDs for those processes: \\ ''svcs -p //servicename//''

//(Optional)// Kill any remaining processes ...repeat this step for all processes that are displayed by the svcs command: \\ ''pkill -9 process-name''

Restore the service: ''svcadm clear //servicename//''

===== Zones =====

==== Basic ====
Here's a decent guide:  [[http://wiki.openindiana.org/oi/Building+with+oi-build|building in a zone]]

== Create ZFS pool for zones ===
  * List of disks:  ''echo | format'' // (look for disk and name) //
  * ''zpool create poolname diskname'' \\ // eg. ''zpool create zonepool c2t1d0'' //
  * Create ZFS filesystems for zone: <code>zfs create -o compression=on -o mountpoint=/zones zonepool/zones
zfs create -o sync=disabled -o atime=off zonepool/zones/oidev</code>
  * Create zone configuration: \\ // (remember NIC name from disabling in nwam) // <code>zonecfg -z oibld
create
set autoboot=true
set zonepath=/zones/oidev/oibld
set ip-type=exclusive
add net
set physical=e1000g1
end
exit</code>
  * Install the zone: ''zoneadm -z oibld install''

=== Initialize the zone's basic local config ===
  * Make the zone "ready": ''zoneadm -z oibld ready''
  * Populate the zone's sysidcfg: <code>cat <<EOF > /zones/oidev/oibld/root/etc/sysidcfg
terminal=xterms
network_interface=PRIMARY {dhcp protocol_ipv6=no}
security_policy=none
name_service=NONE
nfs4_domain=dynamic
timezone=UTC
root_password=NP
EOF</code>

  * Boot the zone with:  ''zoneadm -z oibld boot''
  * Log into the zone with: ''zlogin -C oibld''
  * Change the root password to blank (by hitting return twice for password)

=== Set up DNS ===
  * Populate /etc/resolv.conf and chown it to netadm:netadm
  * Change the hosts line in /etc/nsswitch.conf (add "dns" after "files")

==== Other zone operations ====

=== Removing a zone ===
  * Shut down the zone my-zone using one of the following methods. \\ // The zoneadm shutdown method is preferred //
    * Using zoneadm: \\ ''global# zoneadm -z my-zone shutdown'' \\ ''my-zone''
    * Using zlogin: \\ ''global# zlogin my-zone shutdown'' \\ ''my-zone''
  * Remove the root file system for my-zone. \\ ''global# zoneadm -z my-zone uninstall -F'' \\ // the -F option to force the action generally isn't required //
  * Delete the configuration for my-zone: \\ ''global# zonecfg -z my-zone delete -F'' \\ // the -F option to force the action generally isn't required. //
  * List the zones on the system, to verify that my-zone is no longer listed. \\ ''global# zoneadm list -iv''
  * You will see a display that is similar to the following:<code>ID  NAME     STATUS       PATH                           BRAND      IP
 0  global   running      /                              solaris    shared</code>
