5.3.9. Moving a zone between a sun4u and a sun4v system

[ug] Currently, two architectures with SPARC-processors are available from Sun Microsystems that are both supported by Solaris 10. The sun4u architecture in the larger data center computers with higher single processor performance, and the sun4v architecture in the CMT computers (Chip Multi Threading) with many cores and threads as well as virtualization support. The computer architectures differ slightly at the HW/SW interface, a fact that is reflected in a Solaris 10 installation by different contents in the filesystem.

It can be necessary in data centers for zones to be moved among the various architectures.

First, a zone is created as a template on the sun4u system tiger; the configuration looks as follows:

root@tiger [6] # zonecfg -z template-u info zonename: template-u

zonepath: /zone/template-u

brand: native

autoboot: false bootargs: pool: limitpriv: scheduling-class: ip-type: shared inherit-pkg-dir:

dir: /lib inherit-pkg-dir:

dir: /platform

inherit-pkg-dir: dir: /sbin

inherit-pkg-dir: dir: /usr inherit-pkg-dir: dir: /opt

The installation:

root@tiger [8] # zoneadm -z template-u install Preparing to install zone <template-u>.

Creating list of files to copy from the global zone. Copying <2968> files to the zone.

Initializing zone product registry. Determining zone package initialization order. Preparing to initialize <1515> packages on the zone. Initialized <1515> packages on zone.

Zone <template-u> is initialized.

The file </zone/template-u/root/var/sadm/system/logs/install_log> contains a log of the zone installation.

Next, the configuration is saved for reuse as a file (under /zone):

root@tiger [18] # zonecfg -z template-u export >template-u.export

A new zone with the same configuration can be created as follows on the sun4u system tiger:

root@tiger [19] # zonecfg -z u0 <template-u.export u0: No such zone configured

Use 'create' to begin configuring a new zone.

root@tiger [20] # zonecfg -z u0 set zonepath=/zone/u0

root@tiger [21] # zoneadm -z u0 clone template-u

Cloning zonepath /zone/template-u...
