Sun Microsystems 10 Software installation with provisioning system, Zone migration among systems

Version 3.1-enSolaris 10 Container Guide - 3.1 5. Cookbooks Effective: 30/11/2009

5.3.4. Software installation with provisioning system

[ug] The N1 SPS software can provision software in zones as well. The requirements are:

∙A writable directly where the software can be installed. This can be /opt. /opt is not allowed to be configured as inherit-pkg-dirin this case.

∙If the software need to be installed under /usr or in a different system directory, this can be implemented either with a whole-root zone or with a writable directory (e.g. /usr/local) available in the /usr-tree (created with zonecfg:add fs).

∙The software needs to be able to run in a zone (see above).

5.3.5. Zone migration among systems

[dd]Starting with Solaris 10 11/06, zones can achieved with zoneadm detach/attach zones can be migrated:

be moved among physical systems. This can be

. The following conditions must be observed before

∙Zones must be stopped prior to migration

∙The patch and package status between the two systems must be identical

A local zone can be migrated as follows between systems:

∙ Detach the zone with zoneadm -z <zone> detach

∙Move the zonepath directory to the target system, e.g. in the SAN or with tar/cp

∙ Set up the zone configuration zonecfg -z <zone> create -a <zonepath>

∙Attach the zone zoneadm -z <zone> attach

An installed local zone is detached prior to migration. This process generates all information required to attach this zone to another system. The information is stored in the file <zonepath>/SUNWdetached.xml. The status of the zone is converted from "installed" to "configured". Thus, this zone will subsequently no longer be considered for package installations, patches, booting, etc.

Prior to attaching, the zone configuration can be generated from the SUNWdetached.xml file. Running attach will check on the target system whether the local zone fits on the target system. In addition, it is checked whether the installed packages and patches in the migrated zone and the global zone of the target system have the same version.
